# Description This PR follows up on #16019 with fixes and workflow improvements to the Design tab. Sketching now waits for you to pick a plane, the reference planes stay out of the way until they are needed, and the camera follows the mouse controls set in Preferences, as suggested by @Felix14-v2 in https://github.com/OrcaSlicer/OrcaSlicer/pull/16019#issuecomment-5932747510. It also fixes rendering, camera and Move bugs, which are listed below. https://github.com/user-attachments/assets/6aac0a03-8405-403a-93b2-1fbf95da9fe7 **Improvements:** - Pan and orbit follow Preferences > Control while sketching too. A right-drag no longer ends the polyline chain or drops the point already placed, and in the Touchpad camera style Alt+move and Shift+move orbit and pan while a draw tool is selected. - The XY, XZ and YZ planes are separate labelled squares around the origin, in their axis colours, with dash-dot axes. They no longer cross through the bed as one grey smear. Hovering over a plane greys it out, and selecting one makes it solid. - The reference planes stay hidden until a sketch needs them. A new Origin row in the Feature tree keeps them on screen, and Ctrl+Shift+O toggles it. - A sketch opens only once its plane is chosen. If a flat face or a reference plane is already picked, the sketch opens on it at once. Otherwise the planes appear, and the next plane or face you click opens the sketch. Esc or Cancel leaves without one. - The Bed checkbox is now a row under Origin, and its state is remembered across sessions. Both rows sit above the feature list as fixed view switches. - Zoom to selection is available on Feature tree and Bodies rows and in the right-click menu. - A Sketch button replaces the FEATURES label, the import icons now have an arrow, and the document icons are sized consistently. **Fixes:** - Feature previews no longer z-fight with the bodies. The Hole preview now hides the bodies and shows only the result, as Fillet/Chamfer and Draft already do. - Body edge lines stay in sync with the bodies after undo, hide and delete. - The bed, grid and reference planes stay aligned on every plate, not only the first. - The Fit camera button frames the selection and sketches, or everything on show, instead of always framing the whole bed. - Grabbing a move arrow no longer makes the body jump on the first drag. - Move no longer gets stuck after Esc or a click off the gizmo. Esc and Cancel put the body back, and undo waits until the Move is confirmed or cancelled. - The camera stays still when the first body appears. - The view buttons no longer cover the status line at display scales above 100%. - The import buttons no longer stay highlighted after a click. - The Bodies right-click menu no longer closes at once on Linux. # Screenshots/Recordings/Graphs - **Z fighting issue** Before fix: https://github.com/user-attachments/assets/0da30897-8d81-494a-a206-9b4dfd8fa9c0 After fix: https://github.com/user-attachments/assets/04ccad39-dbbc-4bcf-8d5c-3ba4894cb755 - **Sketch plane rendering** Before: <img width="374" alt="{CCFCEB16-20FA-4202-A5F8-5F2219E44C0B}" src="https://github.com/user-attachments/assets/2dfd19b2-9991-45c7-91e3-e139d111229c" /> After: <img width="1706" height="1258" alt="image" src="https://github.com/user-attachments/assets/3ec89038-4614-4c04-9f20-37bfc50ee5ef" /> - **Wrong body frame lines** Before: https://github.com/user-attachments/assets/81ccae26-2a9d-4ecb-9928-678dbe9fb94c After ## Tests <!-- > Please describe the tests that you have conducted to verify the changes made in this PR. --> <!-- > A guide for users on how to download the artifacts from this PR. --> [How to Download Pull Requests Artifacts for Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)

Stable Release
📥 Download the Latest Stable Release
Visit our GitHub Releases page for the latest stable version of OrcaSlicer, recommended for most users.
Nightly Builds
🌙 Download the Latest Nightly Build
Explore the latest developments in OrcaSlicer with our nightly builds. Feedback on these versions is highly appreciated.
Belt Printer Builds
The nightly release ships two parallel builds: the standard build and a belt-printer build. Both are attached to the same release — tell them apart by the filename suffix:
- Standard — no suffix (e.g.
OrcaSlicer_Windows_Installer_x64_nightly.exe) - Belt —
_beltsuffix (e.g.OrcaSlicer_Windows_Installer_x64_nightly_belt.exe)
The _belt builds add experimental support for belt / conveyor (infinite-Z) printers, where the model is sliced against a tilted belt surface instead of a flat horizontal bed. They include ready-to-use belt printer profiles, the full belt slicing pipeline (mesh rotation and G-code transforms), belt-aware support generation, and a tilted-bed preview.
⚠️ Belt printer support is under active development and is not yet merged into
main— it currently ships only in these parallel_beltbuilds, produced from thebelt-printerbranch. See tracking PR #14394 and the original documentation in #12998.

Some Background
Open-source slicing has always been built on a tradition of collaboration and attribution. Slic3r, created by Alessandro Ranellucci and the RepRap community, laid the foundation. PrusaSlicer by Prusa Research built on Slic3r and acknowledged that heritage. Bambu Studio in turn forked from PrusaSlicer, and SuperSlicer by @supermerill extended PrusaSlicer with community-driven enhancements. Each project carried the work of its predecessors forward, crediting those who came before.
OrcaSlicer began in that same spirit, drawing from BambuStudio, PrusaSlicer, and ideas inspired by CuraSlicer and SuperSlicer. But it has since grown far beyond its origins. Through relentless innovation — introducing advanced calibration tools, precise wall and seam control, tree supports, adaptive slicing, and hundreds of other features — OrcaSlicer has become the most widely used and actively developed open-source slicer in the 3D printing community. Many of its innovations have been adopted by other slicers, making it a driving force for the entire industry.
The OrcaSlicer logo was designed by community member Justin Levine.
