Hello,  
Everytime I try to upload a solid works assembly file this error appears: **Error uploading file xxx.sldasm Internal error occured.**

How can I solve this problem?

Thanks for your time.

Hi @IFS!

Please send the file to my mail address (will pm it to you). Another user had the same issue but fixed it by exporting his assembly as IGES. See if that also works for you and keep me up-to-date!

Cheers and all the best!

Hello @IFS, @jousefm,  
as we can only upload one file at a time, assemblies must be uploaded as a zip archive including all files.  
This should work for Autodesk and Solidworks assemblies.

Best,  
Richard

Thanks for pointing this out @rszoeke!

Assumed that he used a zip file but definitely should have mentioned it.

Best,
