Getting back to a project that would be great if it is finished today. Reread my posts on this program.
I make it sound like you need to use AutoCAd with the Sheet Lighning v6. You don't! It is a stand alone program for $100 that will let you design in 3d, unfold and print the output to paper, or a DXF file.
The Sheet Lightning v6 and SL Pro v6 are designed for doing complex 3d shapes in sheet metal! Paper and sheet metal start out the same - a flat sheet.
All replies to my emails have been quick. Trevor shows a willingness to help out with our design projects. He mentions that he is willing to expand in new directions to help make model designing easier.
