Here is the Shapes
Designed by scyeige
This Excel sheet calculates the flattened (unfolded) shapes for cones, spheres, truncated cones, domes, etc.
Worksheets are protected, but no password was used, so you can just unprotect it if you want just in case any of the formulas are altered or deleted. I would suggest using copies of the program and keep an original untouched one.
This is a fantastic tool for those who make models without a CAD program.
