Thanks Dave. I’m glad you got it working and thanks for the settings write-up. I’ve just updated the guide point scale limits to start from 0.0001 to see if that solves the guide scaling. I’ll send you a .zip for you to try if you like? If it works I can update for the 0.9.4 release.
I think Extrude Manifold is going to be a game-changer for SketchUp users, I’m currently working on making this work for primitives drawn in the center of faces, so we can cut holes in geometry just like in SU with Push/Pull.
Thanks for your comment. If you’re interested in trying the guide scale change can you PM me your email address and I’ll send a patch version through.
