Measurement fails (faces not selectable) on models converted from Creo 2.0 assemblies with an assembly-level revolved cut

Hi,

I’m running into an issue with HOOPS Visualize Web and models converted from Creo Parametric 2.0.

Reproduction steps:

  1. In Creo 2.0, create a part by sketching and using Revolve.
  2. Insert the part into an assembly.
  3. At the assembly level, create a sketch and use a Revolved Cut to remove a portion of the part.
  4. Convert the resulting assembly to SCS/SC using HOOPS Converter.
  5. Load the converted model in HOOPS Visualize Web.

Expected behavior: Measurement (point-to-point, face distance, etc.) should work on the model, and the corresponding faces should be selectable/highlighted when hovering or clicking.

Actual behavior: The converted model cannot be measured — the faces on the model cannot be selected at all. Measurement operators return no valid selection on the affected geometry.

Important observation: When I perform the exact same workflow in Creo 9.0 (part revolve → assembly → assembly-level revolved cut → convert), the converted file works correctly in HOOPS Visualize Web: faces are selectable and measurement functions as expected.

So the issue appears to be specific to files created in Creo 2.0, possibly related to how the assembly-level cut geometry (or the cut-modified faces) is exported/imported by the Creo 2.0 data path in the converter.

Has anyone seen similar behavior with older Creo versions? Is this a known limitation of the Creo 2.0 reader, and is there a workaround (e.g., specific converter options, or saving the assembly in a different way before conversion)? The sample Creo files: creo2.0demo.zip (164.8 KB)

Thanks in advance!
