When you export a flat pattern, e.g., for laser cutting, sometimes you want to add a single line - a cut with the laser, e.g., to facilitate bending. Right now you can make sketches on top of a flat pattern but you cannot export them together into a single dxf. And to merge them in a 2D CAD program afterwards is a hassle and error prone. Would be nice if you could select sketches to export to same file.
In CAM you can export multiple parts - flat pattern and sketches to same DXF using the DXF post file, but then you loose the bend lines information.
