Hi All,
I am trying to design a tube with grooves inside. Starting with two circles to represent the wall, I then placed rectangles where I want the grooves. Now how do I get rid of the interecting lines to show the grooves are open to the tube on the inside?
Second problem. I want to add dimensions using "comments to myself" but I cannot get the whole design to line up with the center of the tube at 0x and 0y. I have grooped everything but there doesnt seem to be any way to move the grooped objects? I orginally placed the first circle at 0X and 0y but somehow it seems to have moved.
Third problem. Having drawn the 2D end of the tube, how do I now convert to 3D and show the length of the tube? My systen crashes when I click 3D.
"Just a short note to applaud this innovative concept! I may even be able to bring some of my long-dreamed about, but never attempted projects into the real world. This is an outstanding service. Incredible! Fantastic!"
