What's new · v2026.10.10.7

Rotating a toolpath keeps its shape

• Rotating a job with the gizmo — flat in the XY plane or tilted in the XZ / YZ planes — no longer distorts its shape, in the 3D view or in the G-code sent to the machine
• Arcs in every plane stay correct when a job is rotated, tilted or scaled
