I have run your latest appimage from today to see the sketcher functionality (maybe wrong thread, I do not know if there is any other thread for this, a moderator may move it if so).

I have just done a rectangle, export two sides as single objects and pad it. Then I create another rectangle perpedicular to one of the exported sides. I wanted to make a sweep of the second rectangle along one of the exports.
When accepting the sweep, a "CopyExport" is created, even if the Export belongs to the same body.

I think the export functionality is a great idea.
