Here is a method I have developed for doing triangulated flat patterns. The process involves exporting DXF points, then processing the point data using a separate utility program (written with REALBasic for the Mac). The program creates a flattened file in the "spline" import format ready to be imported back into your ViaCad or Shark drawing file.
http://homepage.mac.com/rchubb/flat_pattern.zipThe above link will download a ziped folder containing the following:
1. The utility program "flat_pat_gen.app", compiled for both the Mac OX universal and Windows.
2. A ViaCad2d/3d 6 example drawing
3. DXF point files
4. Flattened files ("spline" import format)
5. Tutorial: "What is a triangulation?"
6. Tutorial: "Developable rulings"
The program documentation is self-contained within the program under the "Help" button.
Note: This is the first time I have ever attempted to share one of my programs. I have written a dozen or more Cad/Cam programs. I use these programs to perform a variety of different functions and they all work well for me. Most of the programs are in a continuous state of change/development so don't expect a polished professional package. Please feel free to contact me if you have any questions, suggestion or problems.
