Export STEP file from Creo to Solidworks

Export STEP file from Creo to Solidworks

Hi guys,

I have received a STEP file that had been exported from Creo. It is going to be used to run a flow simulation in Solidworks.

When I import the file into Solidworks and run geometry check I get plenty of zero thickness geometry errors.

Do I have to fix all the errors on part level or is there any faster way to handle the problem?

Why do I see so many zero thickness errors after importing the file into Solidworks?

Thank you in advance for your help!

RE: Export STEP file from Creo to Solidworks

I would request a Parasolid over a STEP. Both SW and CREO are built off the Parasolid kernel and you might get a better model without all the issues. However, that may not be true and if CREO is allowing Zero thickness areas to be created, then SW is going to throw a fit about it.

The question I have is the model all surface data or is it solid? SW prefers Solids over surface data. I don't think FEA will work well with surfaces only, but then again I have never tried it. I always try to get all my models back to solids before I move forward with anything else. If it's not erroring out and you have a solid to work with, you might still be able to get an FEA to work.

Do you know what a zero thickness error is? If not, (as an example) its the intersection of two circles touching. Its really just a point where two edges meet and SW sees that as zero thickness.

RE: Export STEP file from Creo to Solidworks

Hi Scott,

Thank you for your answer.

Finally I have managed to find out how to handle the whole thing. So, the file in Creo has to be modified using 'Shrinkwrap' function that creates merged solid. After exporting such a modified file there are no zero-thickness or any other errors present in the model. From now on the file can be successfully used in CFD simulations.

Best regards,
