A means to "uncraft" or modify your cad.
Either an feature addon to the cad assembler or an upgraded cad assembler block would be nice.

I second this request

Technically, this is called an Issue Tracker, those can be anything from problems, to requests, though it's possible Vazkii doesn't want Requests outside of the subreddit, do remind yourself that not everyone uses it, and GitHub is where the code is hosted, having everything in one place makes it simpler for people looking into the code to do pull requests for whatever is needed. It also means Vazkii won't have to check so many places to know what the community wants or what bugs are surfacing.

I third this request.

Requests belong on the psi subreddit tho, not in the bugtracker
