If your previous flow ratio was `0.98` and you selected the block with a flow rate modifier of `+5`, the new value should be calculated as follows: `0.98x(100+5)/100 = 1.029`. **Remember** to save the filament profile.
 6. Perform the `Pass 2` calibration. This process is similar to `Pass 1`, but a new project with ten blocks will be generated. The flow rate modifiers for this project will range from `-9 to 0`.
 7. Repeat steps 4. and 5. In this case, if your previous flow ratio was 1.029 and you selected the block with a flow rate modifier of -6, the new value should be calculated as follows: `1.029x(100-6)/100 = 0.96726`. **Remember** to save the filament profile.

+## Fuzzy Skin Mode
+
+### Contour
+
+Use "Contour" to apply fuzzy skin only to the outer contour of the model.
+
+### Contour and Hole
+
+Use "Contour and Hole" to apply fuzzy skin to the outer contour and holes of the model. This is useful for models with internal features that you want to highlight.
+
+### All Walls
+
+Use "All Walls" to apply fuzzy skin to external and inner walls of the model.
+
+### Fuzzy Skin Generator Mode
+
+Determines how the fuzzy skin effect will be reproduced:
+
+### Displacement
+
+![Fuzzy-skin-Displacement-mode](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/Fuzzy-skin/Fuzzy-skin-Displacement-mode.png?raw=true)
+
+The classic method is when the pattern on the walls is achieved by shifting the printhead perpendicular to the wall.  
+It gives a predictable result, but decreases the strength entire shells and open the pores inside the walls. It also increases the mechanical stress on the kinematics of the printer. The speed of general printing is slowing down.
+
+### Extrusion
+
+![Fuzzy-skin-Extrusion-mode](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/Fuzzy-skin/Fuzzy-skin-Extrusion-mode.png?raw=true)
+
+The fuzzy skin condition is obtained by changing the amount of extruded plastic as the print head moves linearly. There is no extra load on the kinematics, there is no decrease in the printing speed, the pores do not open, but the drawing turns out to be smoother by a factor of 2. It is suitable for creating "loose" walls to reduce internal stress into extruded plastic, or masking printing defects on the side walls - a matte effect.
+
+> [!CAUTION]
+> The "Fuzzy skin thicknesses" parameter cannot be more than about 70%-125% (selected individually for different conditions) of the nozzle diameter! This is a complex condition that also depends on the height of the layer, and determines how thin the lines can be extruded.  
+> [Arachne](quality_settings_wall_generator#arachne) wall generator mode should also be enabled.
+
+### Combined
+
+![Fuzzy-skin-Combined-mode](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/Fuzzy-skin/Fuzzy-skin-Combined-mode.png?raw=true)
+
+This is a combination of Displacement and Extrusion modes. The clarity of the drawing is the same in the classic mode, but the walls remain strong and tight. The load on the kinematics is 2 times lower. The printing speed is faster than in Displacement mode, but the elapsed time will still be longer.
+
+> [!WARNING]
+> The limits on line thickness are the same as in the Extrusion mode.

-Ironing is a process used to improve the surface finish of 3D prints by smoothing out the top layers. This is achieved by selectively melting the outermost layer of the print, allowing it to flow and fill in any gaps or imperfections.
+Ironing is a process used to improve the surface finish of 3D prints by smoothing out the top layers.

 # Layer Height
 
-This setting controls how tall each printed layer will be. Typically, a smaller layer height produces a better-looking part with less jagged edges, especially around curved sections (like the top of a sphere). However, lower layer heights mean more layers to print, proportionally increasing print time.
+Layer height defines the vertical thickness of each printed layer, playing a crucial role in both print quality and printing speed.
 
-## Tips
+Using smaller layer heights increases print time but results in:
 
-1. **The optimal layer height depends on the size of your nozzle**. The set layer height must not be taller than 80% of the diameter of the nozzle, else there is little "squish" between the printed layer and the layer below, leading to weaker parts.
+- Smoother surface finishes
+- Less noticeable layer lines
+- Enhanced detail on curves
+- [Better performance on overhangs](#layer-height-overhangs-impacts)
 
-2. While technically there is no limit to how small a layer height one can use, **typically most printers struggle to print reliably with a layer height that is smaller than 20% of the nozzle diameter**. This is because with smaller layer heights, less material is extruded per mm and, at some point, the tolerances of the extruder system result in variations in the flow to such an extent that visible artifacts occur, especially if printing at high speeds.
+![layer-height-spheres](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/Precision/layer-height-spheres.png?raw=true)
 
-For example, it is not uncommon to see "fish scale" type patterns on external walls when printing with a 0.4 mm nozzle at 0.08 mm layer height at speeds of 200mm/sec+. If you observe that pattern, simply increase your layer height to 30% of your nozzle height and/or slow down the print speed considerably.

+
+## Layer Height Guidelines
+
+Usually, the optimal range for layer height is between 20% and 80% of the nozzle diameter.
+
+- **Below 20%:** Flow inconsistencies and "fish scale" patterns may occur, especially at high speeds.
+- **Over 80%:** Increased risk of layer adhesion issues and reduced print quality.
 
 ## First Layer Height
 
-This setting controls how tall the first layer of the print will be. Typically, this is set to 50% of the nozzle width for optimal bed adhesion.
+Controls the thickness of the initial layer.  
+A thicker first layer improves bed adhesion and compensates for build surface imperfections.
 
-### Tip
+**Recommended:** 0.25mm for 0.4mm nozzle (62.5% of nozzle diameter)  
+**Maximum:** 65% of nozzle diameter
 
-A thicker first layer is more forgiving to slight variations to the evenness of the build surface, resulting in a more uniform, visually, first layer. Set it to 0.25mm for a 0.4mm nozzle, for example, if your build surface is uneven or your printer has a slightly inconsistent z offset between print runs. However, as a rule of thumb, try not to exceed 65% of the nozzle width so as to not compromise bed adhesion too much.
+## Layer Height Overhangs Impacts
+
+Layer height directly affects [overhang angle](quality_settings_overhangs#maximum-angle) capability and quality.
+
+![layer-height](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/Precision/layer-height.svg?raw=true)
+
+**Smaller layer heights** enable steeper overhangs by reducing the unsupported distance between layers, while **larger layer heights** increase this gap, leading to more sagging and requiring support material at shallower angles.

 # Line Width
 
-These settings control how wide the extruded lines are.
+These settings define how wide each extruded line of filament will be.  
+Line width can be configured in two ways:
 
-- **Default:** The default line width in mm or as a percentage of the nozzle size.
+- Fixed value in millimeters (mm)
+- Percentage of the nozzle diameter
 
-- **First Layer:** The line width of the first layer. Typically, this is wider than the rest of the print, to promote better bed adhesion. See tips below for why.
+> [!TIP]
+> Using percentages allows the slicer to automatically adjust the line width when the nozzle size changes, helping maintain consistent print quality across different nozzle sizes.
 
-- **Outer Wall:** The line width in mm or as a percentage of the nozzle size used when printing the model’s external wall perimeters.
+A good starting point is setting the line width to **100% of the nozzle diameter**. Values below this may lead to poor adhesion, while values above **150%** can cause **over-extrusion**, resulting in blobs or poor surface quality.  
+However, slightly wider lines generally improve **layer bonding** and **print strength**, especially for internal features like walls and infill.
 
-- **Inner Wall:** The line width in mm or as a percentage of the nozzle size used when printing the model’s internal wall perimeters.
+> [!NOTE]
+> **100% line width will extrude slightly narrower than the nozzle**, but once squished onto the layer below, it flattens to match the nozzle size.  
+> You can read more on the flow math here: [Flow Math](https://manual.slic3r.org/advanced/flow-math).
 
-- **Top Surface:** The line width in mm or as a percentage of the nozzle size used when printing the model’s top surface.
+> [!IMPORTANT]
+> This will match only if using the [**Classic** wall generator](quality_settings_wall_generator#classic).  
+> [**Arachne**](quality_settings_wall_generator#arachne) will adjust the line width dynamically based on the model's geometry, using this values as a reference.
 
-- **Sparse Infill:** The line width in mm or as a percentage of the nozzle size used when printing the model’s sparse infill.
+## Line Types
 
-- **Internal Solid Infill:** The line width in mm or as a percentage of the nozzle size used when printing the model’s internal solid infill.
+In OrcaSlicer, you can assign different line widths to specific parts of the print. Each type can be customized:
 
-- **Support:** The line width in mm or as a percentage of the nozzle size used when printing the model’s support structures.
+### Default
 
-## Tips
+Fallback value used when a specific line width is not set (set to `0`).
 
-1. **Typically, the line width will be anything from 100% up to 150% of the nozzle width**. Due to the way the slicer’s flow math works, a 100% line width will attempt to extrude slightly “smaller” than the nozzle size and when squished onto the layer below will match the nozzle orifice. You can read more on the flow math here: [Flow Math](https://manual.slic3r.org/advanced/flow-math).
+### First Layer
 
-2. **For most cases, the minimum acceptable recommended line width is 105% of the nozzle diameter**, typically reserved for the outer walls, where greater precision is required. A wider line is less precise than a thinner line.
+A wider first layer (with a higher [first layer height](quality_settings_layer_height#first-layer-height)) improves bed adhesion and compensates for uneven build surfaces.
 
-3. **Wider lines provide better adhesion to the layer below**, as the material is squished more with the previous layer. For parts that need to be strong, setting this value to 120-150% of the nozzle diameter is recommended and has been experimentally proven to significantly increase part strength.
+### Outer Wall
 
-4. **Wider lines improve step over and overhang appearance**, i.e., the overlap of the currently printed line to the surface below. So, if you are printing models with overhangs, setting a larger external perimeter line width will improve the overhang’s appearance to an extent.
+Controls dimensional accuracy and surface finish.  
+Recommended: **105%–120%** of the nozzle diameter for clean overhangs and detail.
 
-5. **For top surfaces, typically a value of ~100%-105% of the nozzle width is recommended** as it provides the most precision, compared to a wider line.
+### Inner Wall
 
-6. **For external walls, you need to strike a balance between precision and step over and, consequently, overhang appearance.** Typically these values are set to ~105% of nozzle diameter for models with limited overhangs up to ~120% for models with more significant overhangs.
+Can be set wider than the outer wall to enhance structural strength.  
+Typical value: **≥120%**.
 
-7. **For internal walls, you typically want to maximize part strength**, so a good starting point is approximately 120% of the nozzle width, which gives a good balance between print speed, accuracy, and material use. However, depending on the model, larger or smaller line widths may make sense in order to reduce gap fill and/or line width variations if you are using Arachne.
+### Top Surface
 
-8. **Don’t feel constrained to have wider internal wall lines compared to external ones**. While this is the default for most profiles, for models where significant overhangs are present, printing wider external walls compared to the internal ones may yield better overhang quality without increasing material use!
+Affects the quality of visible top layers.  
+Recommended: **100%–105%** for smooth results without over-extrusion.
 
-9. **For sparse infill, the line width also affects how dense, visually, the sparse infill will be.** The sparse infill aims to extrude a set amount of material based on the percentage infill selected. When increasing the line width, the space between the sparse infill extrusions is larger in order to roughly maintain the same material usage. Typically for sparse infill, a value of 120% of nozzle diameter is a good starting point.
+### Sparse Infill
 
-10. **For supports, using 100% or less line width will make the supports weaker** by reducing their layer adhesion, making them easier to remove.
+Recommended to use a conservative value, typically around 115% to improve layer adhesion without getting near volumetric flow limitations.  
+If you need stronger infill, it's recommended to use [infill line multiplier](strength_settings_infill#fill-multiline) when possible.
 
-11. **If your printer is limited mechanically, try to maintain the material flow as consistent as possible between critical features of your model**, to ease the load on the extruder having to adapt its flow between them. This is especially useful for printers that do not use pressure advance/linear advance and if your extruder is not as capable mechanically. You can do that by adjusting the line widths and speeds to reduce the variation between critical features (e.g., external and internal wall flow). For example, print them at the same speed and the same line width, or print the external perimeter slightly wider and slightly slower than the internal perimeter. Material flow can be visualized in the sliced model – flow drop down.
+### Internal Solid Infill
+
+Used for solid top/bottom layers or [100% infill](strength_settings_infill##sparse-infill-density).  
+Recommended: **~110%** for good layer adhesion and visual quality.
+
+### Support
+
+Typically set to **100%** to balance material usage and functionality. Reducing it too much can lead to weak support structures that may not hold up during printing or break easily during removal leaving debris on the model.

 ### Reverse internal only
 
-Apply the reverse perimeters logic only on internal perimeters.  
-This setting greatly reduces part stresses as they are now distributed in alternating directions. This should reduce part warping while also maintaining external wall quality. This feature can be very useful for warp prone material, like ABS/ASA, and also for elastic filaments, like TPU and Silk PLA. It can also help reduce warping on floating regions over supports.  
-For this setting to be the most effective, it is recommended to set the Reverse Threshold to 0 so that all internal walls print in alternating directions on even layers irrespective of their overhang degree.
+A simple way to reduce the texture on the outer wall is to only reverse the internal walls.
+This will still provide almost all of the benefits of alternating extrusion direction on even layers (if using [inner/outer](quality_settings_wall_and_surfaces#innerouter)), but the outer wall will be printed in the same direction, resulting in a smoother surface finish.
 
 ### Reverse threshold
 
-Number of mm the overhang need to be for the reversal to be considered useful. Can be a % of the perimeter width.

+- **mm**: A fixed distance in millimeters.

+
+When using this setting, the walls will make the reversal texture in the layers where the overhang is above the threshold, and the rest of the walls will be printed in the normal direction.
+This could result in uneven texture, sometimes considered worse than the full reversal texture, so it is recommended to use this setting only if you are sure that the overhang reversal will not be useful for your model.

+
+#### Scarf joint seam Type
+
+- **Contour:** Applies scarf seams exclusively to the outermost perimeter of the model.
+- **Contour and hole:** Extends scarf seams to both the outer perimeter and the inner walls surrounding holes within the part.
+
+#### Conditional scarf joint
+
+Dynamically applies scarf joints only on smooth, curved perimeters where traditional seams would be visually prominent. Sharp corners will still use standard seams to maintain dimensional accuracy.
+
+#### Scarf joint speed
+
+This option sets the printing speed for scarf joints.  
+It is recommended to print scarf joints at a slow speed (less than 100 mm/s).  
+It's also advisable to enable [Extrusion rate smoothing](speed_settings_advanced) if the set speed varies significantly from the speed of the outer or inner walls. If the speed specified here is higher than the speed of the outer or inner walls, the printer will default to the slower of the two speeds. When specified as a percentage (e.g., 80%), the speed is calculated based on the respective outer or inner wall speed. The default value is set to 100%.
+
+#### Scarf joint height
+
+Defines the vertical offset for the start of the scarf ramp, specified either in millimeters or as a percentage of the current layer height.  
+A value of 0 means the scarf begins at the same height as the current layer and ramps up to the full layer height over the scarf length.  
+For example, on the second layer with a 0.2 mm layer height, setting this to 50% (0.1 mm) will start the scarf at 0.3 mm and ramp up to 0.4 mm by the end of the scarf length, while the rest of the lines print at 0.4 mm.  
+This setting helps create a smoother transition and can reduce visible seam artifacts.
+
+#### Scarf around entire wall
+
+If enabled, the scarf joint wraps around the full perimeter of the wall. Typically disabled, as this may increase print time without significant seam improvement.
+
+#### Scarf length
+
+Defines the horizontal length over which the scarf ramp transitions. A value of 0 disables the scarf joint. The default (e.g. 20 mm) generally offers smooth and effective blending.
+
+#### Scarf steps
+
+Minimum number of segments used to build the scarf transition.  
+More steps create a smoother gradient, but the default value (10) is sufficient in most cases.
+
+#### Scarf joint flow ratio
+
+Adjusts extrusion flow during scarf printing. A value of 100% applies standard flow. Lower values reduce flow but may introduce under-extrusion.  
+Recommended to keep at 100%.
+
+#### Scarf joint for inner walls
+
+When enabled, scarf joints are also applied to inner perimeters (e.g., holes). This has minimal visual impact and is usually left disabled unless inner seam quality is a priority.
+
+### Role based wipe speed
+
+Controls the speed of a wipe motion, i.e., how fast the nozzle will move over a printed area to "clean" it before traveling to another area of the model.  
+It is recommended to turn this option on, to ensure the nozzle performs the wipe motion with the same speed that the feature was printed with.
 
 ### Wipe speed
 
 If role-based wipe speed is disabled, set this field to the absolute wipe speed or as a percentage over the travel speed.

-When finishing printing a "loop" (i.e., an extrusion that starts and ends at the same point), move the nozzle slightly inwards towards the part. That move aims to reduce seam unevenness by tucking in the end of the seam to the part. It also slightly cleans the nozzle before traveling to the next area of the model, reducing stringing.

 ### Wipe Before External
 
 To minimize the visibility of potential over-extrusion at the start of an external perimeter, the de-retraction move is performed slightly on the inside of the model and, hence, the start of the external perimeter. That way, any potential over-extrusion is hidden from the outside surface.
 
-  This is useful when printing with Outer/Inner or Inner/Outer/Inner wall print order, as in these modes, it is more likely an external perimeter is printed immediately after a de-retraction move, which would cause slight extrusion variance at the start of a seam.

 ## Avoid crossing walls
 
-Maximum detour distance for avoiding crossing wall. Don't detour if the detour distance is larger than this value. Detour length could be specified either as an absolute value or as percentage (for example 50%) of a direct travel path. Zero to disable.
+This option instructs the slicer to avoid crossing perimeters (walls) during travel moves.  
+Instead of traveling directly through a wall, the print head will detour around it, which can significantly reduce surface defects and stringing.
+
+While this increases print time slightly, the improvement in print quality—especially with materials prone to stringing like **PETG** or **TPU**, often justifies the tradeoff.  
+Highly recommended for detailed or aesthetic prints.

 ### Max detour length

+Defines the maximum distance the printer is allowed to detour to avoid crossing a wall.
+Can be set as:
 
-Zero will detour no matter the distance.
+- **Absolute value in millimeters:** exactly how far the detour can extend (e.g., `5mm`).
+- **Percentage** of the direct travel path (e.g., `50%`).
+- **0** disables the **limit** and allows detours of **any length**.
+
+Use this setting to balance between print time and wall quality—longer detours mean fewer wall crossings but slower prints.

If printing with a high external perimeter speed, this parameter may introduce slight artifacts when slowing down due to the large variance in print speeds. If you notice artifacts, ensure your pressure advance is tuned correctly.

+Each instruction is written by a combination of symbols and numbers and separated by a comma or a space.
+For more complex instructions, autoformatting is used to make the template easier to read.
+
+> [!NOTE]
+> All examples are shown with a 5% density rectilinear infill on a model of a cube 20x20x20mm which has 100 layers of 0.2mm thickness. Without walls and upper and lower shells. Initial angle is 0.
+
+### Simple absolute instructions
+
+They include a simple definition of the angle for each layer. Note that the initial setting of this angle is also affected by the value in the sparse or solid infill angle field.
+
+- `0`, `15`, `45.5`, `256.5605`... - just fill at the existing angle. The initial direction starts at the X-axis, and the acceptable range of values is from 0 to 360  
+  - `0` as well as `+0`, `-0` or just empty template  
+  ![0](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/0.png?raw=true)
+  - `45`  
+  ![45](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/45.png?raw=true)
+  - `0, 30` - is a simple alternation through each layer in the direction of 0 and 30 degrees.  
+  ![0-30](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/0-30.png?raw=true)
+- `0%`, `10%`, `25%`, `100%`... - infill angle determined from relative terms from a full turn of 360 degree rotation. Rotate by 0, 36, 90, and 0 degrees.  
+  - `25%` - the equivalent of `90` instruction.  
+  ![90](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/90.png?raw=true) 
+- `30, 60, 90, 120, 150, 0` - a more complex command defines a turn every layer at 30 degrees. At the end of the template line, the next instruction is read first, and this process continues until the entire height of the model is filled.
+
+### Relative instructions
+
+- `+30` - this is a short instruction for counterclockwise rotation. The equivalent of `30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 0` or `30, 60, 90, 120, 150, 0` instruction.  
+  ![+30](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/+30.png?raw=true)
+- `-30` - this is the same instruction, but with clockwise rotation. The equivalent of `330, 300, 270, 240, 210, 180, 150, 120, 90, 60, 30, 0` or `330, 300, 270, 240, 210, 0` instruction.  
+- `+150` - you can specify a different multiple of the irrational angle for better fill dispersion = `150, 300, 90, 240, 30, 180, 330, 120, 270, 60, 210, 0` ...  
+- `+45` - The equivalent of `45, 90, 135, 180, 225, 270, 315, 0` or `45, 90, 135, 0` instruction.  
+  ![+45](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/+45.png?raw=true)
+- `+90` - The equivalent of `90, 180, 270, 0` or `90, 0` instruction.  
+  ![+90](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/+90.png?raw=true)
+- `+15%` - useful for dividing angles on a decimal basis = `54, 108, 162, 270, 324, 18, 72, 126, 180, 234, 288, 342, 36, 90, 144, 196, 252, 306, 0` ...  
+- `+30, +90` - a complex instruction setting the rotation of each layer in these positions = `30, 120, 150, 240, 270, 0` ...  
+  ![+30+90](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/+30+90.png?raw=true)
+- `0, +30, +90` - a complex instruction setting the rotation of each layer in these positions = `0, 30, 120` ...  
+  ![0+30+90](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/0+30+90.png?raw=true)
+
+### Repetitive, adjusting and one-time instructions
+
+- `5, 10, +20` - simple instructions without modifiers. Sets the angles in sequence = 5, 10, 30, 5, 10, 30, 5, 10 ...
+- `5, 10*, +20` - the `*` sign sets the initial angle without quantitative designation and without layer processing. It is useful for setting the orientation of a group of layers, which will be described below. Sets the angles in sequence = 5, 30, 5, 30, 5, 30, 5 ...
+- `5, 10!, +20` - the `!` sign indicates that the instruction will be executed only once for the entire height of the model. Sets the angles in sequence = 5, 10, 30, 5, 25, 5, 25, 5 ...
+- `5, 10*!, +20` - the combination of `*` and `!` signs is also usable = 5, 30, 5, 25, 5, 25, 5, 25 ...
+- `5, 10*3, +20` - if a number is written after the `*` sign, it indicates the number of repetitions of this instruction. Sets the angles in sequence = 5, 10, 10, 10, 30, 5, 10, 10, 10, 30, 5, 10 ...
+
+### Range instructions
+
+A combined set of layers will be organized, where the rotation of one layer relative to the other will also be predetermined.
+You can specify how many layers will be rotated by a certain angle, and according to which mathematical law this rotation will be performed. This law is determined by writing a certain symbol and specifying a numeric value after it.
+The following signs are available that determine the shape of the turn: `/` `#` `#-` `|` `N` `n` `Z` `z` `L` `l` `U` `u` `Q` `q` `$` `~` `^`. For their purpose, see [joint sign](#joint-sign).
+
+Also, after the numeric value there is a range modifier, then this rotation will occur according to the described length.
+The following modifiers are available that determine the range of turn: `mm` `cm` `m` `'` `"` `#` `%`. For their purpose, see [length modifier](#length-modifier).
+
+If there is a `-` sign before the numeric value, then the initial fill angle changes with the final one. This is useful for joining the linear infills in some cases. Absolute values of the rotation angle using the range instructions have no effect.
+It is important to know that this will not be the exact length, but will be tied to the nearest layer from below.
+
+- `+45/100` - rotate the next 100 layers linearly at a 45 degree angle. For this model, this instruction is equivalent to `+45/100%` as it contains 100 layers.  
+  ![+45-100](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/+45-100.png?raw=true)
+- When changing the height of the instruction `+45/50` or `+45/50%` - the final angle will be 90, as the turn will occur twice.  
+  ![+45-50](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/+45-50.png?raw=true)
+- `-50%Z1cm` - rotate one centimeter of infill by sinus function at a 180 degree CW.
+
+### Constant layer number instructions
+
+There are 2 letter signs `T` and `B` that can determine the number of shell layers on the top and bottom of the model. It is useful for calculating skipping this amount to align the fill, or inserting the required number of horizontal solid bulkheads.
+
+- `B!, +30` - skip the first shell layers from rotation, then fill with 30 degree turn each layer  
+- `+30/1cm, T` - rotate one centimeter of infill linearly at a 30 degree angle, then skip the number of layers equal to the count of the upper shell layers without rotation.  
+
+### Solid layers into sparse infill instructions
+
+The following instructions allow you to embed solid layers in a sparse fill. The following commands are available `D` `S` `O` `M` `R`. For their purpose, see [solid sign](#solid-sign).
+
+It is possible to combine them with the rotation method and layer number constant - `DT` `S/` `M#` `OB`...
+
+- `#14, +15R` - put 14 layers of sparse infill then put one rectilinear layer of solid infill with 15 degree turn  
+  ![14+15R](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/14+15R.png?raw=true)
+- `B!, 240M3, #25` - skip the first shell layers from rotation, fill model with 3 solid monotonic layers at 240 degrees, then put 25 sparse layers at the same angle  
+- `+30/1cm, ST` - rotate one centimeter of infill linearly at 30 degrees, then put solid layers equal to the count of the top shell layers  
+- `+30M3` or `+90M/3` - fill whole model with solid infill with 30 degree turn at each layer  
+
+## Complex template examples
+
+- `+10L25%, -10l25%, -10L25%, +10l25%` - fill the model with sine period with 10 degree amplitude  
+  ![10period](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/10period.png?raw=true)
+- `+30/-10#` - rotate the infill at height of 10 standard layers (or @ standard layer height is 0.2mm x 10 = 2mm) inverse linearly at a 30 degree angle.  
+  ![+30-10](https://github.com/SoftFever/OrcaSlicer/blob/main/doc/images/fill/Template-metalanguage/+30-10.png?raw=true)
+- `+360~100%` or `+100%~100%` - fill the model with infill with random direction at each layer.
