Hello, http://athena.zcu.cz/kurzy/tedo/000/HTML/57/test/index-06.htm / priklad kota 50 ../ I have trouble with one drawing. I have to anch the hole radius. The problem is that the size of the hole in the outline is quite small - I solved this by extending the kitten. Now the nut when I extend the kit is the line, indicated by thick or weak thickness. ? Thank you for your help ! Enjoy the rest of your day.
