Hi,

Since upgrading to Solidworks 2026 i have not been able to use any of the scan to 3D features, even opening files that i have previously used these features no longer work. If i try using curve wizard i get the error "Some curves can't be exported successfully because of self-interacting". In the second image it shows the previous use of curve wizard in the same file used in 2025.

If i run surface wizard it just tells me all the surfaces have errors.

Using mesh prep and simplifying the mesh, reducing noise etc.. makes no difference 

Ive tried doing this with a basic cube and I'm still having the same problem.
