🐞 Description of the bug

The following STEP file ply_boundaries.step.txt [1] cannot be loaded and then exported to the PMDAT format.

The following exception occurs:

CRITICAL -  -  logger - handle_exception - Uncaught exception
Traceback (most recent call last):
  File "<script_location>\pmdat_export_error.py", line 5, in <module>
    design.export_to_pmdb(".")

📝 Steps to reproduce

• Download the STEP file linked above
• Run the following code, changing the path to the file as needed:

  from ansys.geometry.core import launch_modeler_with_geometry_service
  
  modeler = launch_modeler_with_geometry_service()
  design = modeler.open_file("ply_boundaries.step")
  design.export_to_pmdb(".")

Hmm seems like you are using the local version of the Geometry Service (meaning, it is on your filesystem). Could you try running the script with the following modification?

https://geometry.docs.pyansys.com/version/0.6/api/ansys/geometry/core/modeler/Modeler.html#Modeler.open_file

design = modeler.open_file("ply_boundaries.step", upload_to_server=False)
design.export_to_pmdb()

[RobPasMue]

Nonetheless it seems like the export/download API is the one failing... Let's give it a try to

https://geometry.docs.pyansys.com/version/0.6/api/ansys/geometry/core/designer/design/Design.html#Design.save

try calling

design.save("ply_boundaries.pmdb")

Fingers crossed...

[greschd]

upload_to_server=False

Produces the same error

design.save("ply_boundaries.pmdb")

Produces the following error:

ansys.geometry.core.errors.GeometryExitedError: Geometry service connection terminated: Path cannot be the empty string or all whitespace.

Can you reproduce the issue with the STEP file above? Maybe I just got a bad daily build.

Otherwise, I suspect it's specific to this file. With another STEP file the original code works, but the design.save variant produces the same exception. On the original file, export_to_fmd also works.

Hi @greschd - I came back to this issue after some time (sorry for the delay). I am able to reproduce the same problem you report. However, looking into the server logs I found an interesting error...

My guess is that something is going on when exporting to PMDB only (and specifically for this file) - because prior to these errors you can see that the export to scdocx worked just fine. I'll report it to the PMDB plugin team so that they can investigate.

FYI - I also tried it with SpaceClaim and it also failed so it might be something broader (not specific to the Geometry Service)...
