An issue came in today that I think will benefit the community to see troubleshooting techniques as we work toward a resolution.
Geopak ss3 no longer will no longer drape elements, using a 2d file and tin, to a 3d file. it does work in ss2.
I have verified that this does not work and have filed a defect against the product. Defect number is D-127545
