Any advice on a plugin that will create a clean outline of the projection of a shape onto a plane? Thanks. R.
You may want to try FredoPortrait

The approach is slightly different from a projection or flattening, since it takes the picture of the model (which is 2D) and create the silhouette out of it.
I don't know if your model would work but it may be worth trying.
