When importing this .stp file through Datasmith, the normals are inverted upon import. Attached are screenshots of the normals in AutoDesk Alias and McNeel Rhino.

This was reported and tested in 4.24.1 (CL-10757647). This was reproduced in 4.23.1 (CL-9631420) and Main 4.25 (CL-10985206).

Steps to Reproduce
  1. Open the UE4 Editor and create a Blank Architecture, Engineering, and Construction project
  2. Click the Datasmith icon and import the attached .stp file
  3. Compare the imported file to the attached screenshots

Results: Normals are inverted compared to CAD

Expected: Surface orientation should be the same as in CAD.
