I opened a design that was last edited in Build 300 in the latest Build 305. All the paths that had been V-carve paths are now No Offset paths. There’s no way to just convert existing paths to and from V-carve, so I have to re-create all of them. This is a real pain.
Please send any such problem files in to support@carbide3d.com — we’ll add them to our test suite and hopefully work out such issues.
