We just uploaded Carbide Create Build 289.
It includes the following:
New Features
- Mirroring/flipping.
- Rounded, tee, and dogbone corners for rectangles.
- Changed Save to separate Save / Save As.
- Added filename to title bar.
Bug fixes
- Don't reset toolpath parameter when editing a tool.
- Fixed slow plunge. The toolpath now rapids down to retract plane, then plunges from there.
