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.
