COOSBAYLUMBER, thanks for you candid information. Actually I am quite familiar with and working on PC's as I am a network engineer. On top of that, I work for an engineering company with access to large scanners, copiers, and plotters. I have been scratch building (plans building) giant scale warbirds for years. So I am quite familiar with the construction methods and work needed. What I am not familiar with is how to use CAD software. What I do know is that I do not need to purchase some high dollar CAD program for basic 2D drawing as I am not designing a building with all of the plumbing, electrical, etc. My goal is simple. Since I cannot find a plan large enough to meet what I am looking for, I would either like to modify an existing plan or draw one from a 3 view. Initially I was thinking I could scan an existing plan into bmp or tif format and then import it into a CAD program. Enlarge the plan to meet my criteria, change the now irregular wood stock sizes and corresponding notches and change the design of some areas per my design ideas including the improvement of the scale outline. This is my true goal, not necessarily designing from the ground up.

That being said, can you or anyone recommend a CAD program to accomplish this? I have looked at TurboCad LE and Profesional. I am also looking at ModelCAD 3000, does anyone have input on this product?

Thanks for all of the input.

Jay
