Here I am again with another method to try to build a sphere or rather a disco ball, I can't get out a unfolder worthy of the name for this piece of sheet metal after the 2nd removal of material
Before no problem, I would also like to print a text and then do a material removal to pierce it following the text, did I make myself understood? Well a lot of question, finally thank you if there are answers I put a screenshot.
Can you post your piece with the main dimensions. I think you should use the method proposed several times by @ac cobra (it seems to me) which is to start from a cylinder or portion of a cylinder that is quite easy to flatten. On the other hand, if you want concave parts, it's not possible with SW. If it is portions of a cylinder "the mirrors of the disco balls are flat" then the method of our eminent colleague seems to me to be the right solution.
