Need some help. I have been trying to create pattern part in assembly/Solid Edge. The part is supposed to be revolved around a cylinder attached with holes patterned around its circumfrence. I was able to create the patterned holes arond the circumfrence. Now, how do I attached this another part to the hole pattern?? Another problem is with AUTOCAD, I have been trying to create 2D drawing from 3D parts, it's been long time since I used AUTOCAD, I forget the process by which you can have specific lines as hidden while going to 2D from 3D. I believe there are experts in Sajha who can help in this.
