I can’t reproduce now. It’s ok. I think was when laying multiple pieces on top of each other then no actual way to back back back (undo) out to see and work on the base parts again. I think I realized with some functionality you only get one shot at it. So I started a new design and now build up from the base part, every drawing or part is built/designed away from the centre axis (main part) then when happy I lay each piece onto the centre axis body. Sort of how you would in real life. So all part workings (learning good and bad) and designs are laying around the outside in a work area.
Can I leave a text box within the design? So I can leave notes of my thoughts / logic within the design spaces.
