Hi there!
I don't use KS about 3 years but clearly remember I worked with .wire without any problem before. Now I try import my different .wire files (fresh and old) on two different Keyshot versions - licensed 6.3.23 (C:/) and trial 4.3.18 (D:/) with different import option, but everytime I get "file doesn't contain 3d geometry." I try placed .wire in both disk but I get the same. Alias Studio version 2016.
OK, I solved that! It was a problem with installing .wire files in the system. Update Alias Studio by SP1 is helped.
Thank you for the hint to the solution.
