Hi Ana Regina,
I got that same warning trying to open the SC geometry in DM. Not sure why.
I made a new archive that used DesignModeler. I also put the Parasolid file in the user_files folder. Here is the link https://jmp.sh/VQun7W5W
If you are going to be making models for different stents, you should learn how to do this slicing. I am happy to show you if you want to setup a zoom meeting. I can show you what you need to know in under an hour.
Regards,
Peter
