Problem exporting sat file

Coreform Cubit Importing/Exporting
#1

Cubit Version: 2020.2
Platform: Windows

Hello,
I want to export a non planar surface that I created from various curves with the following command:

create surface skin curve all
delete curve all

I want to export the surface to .sat file, so I use the command:

export acis ‘topo_surf_5km.sat’ overwrite

But I get this:

export acis ‘topo_surf_5km.sat’ overwrite
ERROR: C:/Users/marcmath/Documents/Italie/mesh/test_nov2019/topo/topo_surf_italy_5km.jou (11775). No geometry exported. Must set geometry engine to another type.
Set the geometry engine appropriately to export the following geometry:
Body 1 is of Geometry Engine type ACIS
WARNING: No Valid ACIS Geometry found for export.
Finished Command: export acis “topo_surf_5km.sat” overwrite

I used exactly the same script with Trelis and it worked fine. On Cubit it doesn’t work anymore.
What can I do to solve my problem ?
Thanks in advance
Mathilde

Hi shifq. Welcome to the forum!

The error given above sounds like the geometry was created using facet based geometry which is not supported by the ACIS geometry engine.

Do you have the specific error message? How did you create your geometry? Are you saving the file to a folder where you have write permissions?

Thanks,
Karl
