Hello ..I am using CATIA V5. I have a question. I want to convert the modeling to STL file and output it(using 3D print), but I used hole for the bolt part in the design function. Is it OK to be on the stl file?.. example , When you do thread m 3 with the hole function, the pitch shape will not appear on the modeling display. Is there a stl file in the same way?If it is not appropriate to output with the hole function, is there another way to draw the pitch directly?I'm very worried. Even if you receive an answer by e-mail, it will be done. e-mail: nrkim1919@gmail.com Thank you
