wishing to make a box with 3mm thick walls I create a box using solid box tool then offset srf 3mm.
Boolean Differnce command, choose outer then inner and it fails.
Objects do not intersect…nothing done it says.
why cant I boolean difference this using the inner one as the ‘cutter’, surely it intersects as its inside !
I am having to make boxes up in rhino to estimate box weight for ebay selling as its not practical to go running about to supermarkets getting boxes incase the item never sells, and listings require box size and weight, and postage costs, all before it sells, if ever. Pain in the %$£&.
so use spec gravity of my cardboard and knock out a quick box in rhino then add flaps etc, and padding.
