Our company has updated Alias to 2021.3.1 and now Datasmith crashed when importing .wire files. Previously we had Alias 2019 and Alias 2021.1 installed. Now just Alias 2021.3.1 and then the issue began. When we had Alias 2019 and Alias 2021.1 installed Datasmith worked when importing .wire files.

I also tested the Datasmith .wire imported with UE 4.26.2, UE 4.27.0 Preview2 and UE 5.0 Early Access 2 all getting crashes.


Steps to Reproduce



  • Have a project with Datasmith CAD Importer enabled
  • Have Alias Studio 2021.3 or later version install on your computer


Import QUARTER_GLASS_BLACKOUT_13W0097CG_01A_11102012.wire file with Datasmith

A geometry should be imported in EU
