Hi Anders,
I have found many curved parts with pattern on the curved surface. Also
I think of stickers that can be done with such a program.
I think it could work as follow:
1) Do a scan of the curved part (You need to have 90° angle to the
middle of the patterned surface.)
2) Create a LDraw file from that scan that is flat.
3) Use the new program
3a) You have to tell the program at which point it should be centered
(see point 1)
3b) You have to tell the program the patterned part file.
4) Output will be generated.
Any additional thoughts are welcome.
