Hi,

I am working on making a negative mold for a feather. I have already constructed the positive mold from using Scan to 3D to import a 3D scanned mesh of a feather, then turned the mesh into a surface, and used the surface to make a mold with the curvature of the feather on one side and a flat bottom on the other.  My goal is to also create a mold within a block with the negative of the feather cut out.

I have tried several things, but can't seem to figure this out.  Perhaps there is a way to put the feather inside of a block and subtract the feather?  Or use the feather surface as a cookie cutter?

Attached are both my attempt (as you will see I can't get the bottom to align with the block-the bottom of the feather extrudes beyond the block-I have tried slicing with a plane but it won't work) and the solid feather model.

Thank you so much!
