Hi,

I have a large assembly, in .step, composed of +200 parts that I would like to include as a sub-assembly of a larger (main) assembly.

However, Solidworks 2018 gets very slow, and it also crashes a lot because it has to read all the components of this assembly all the time.

My question is: how can I save the large assembly(+200 parts) as a single part. I would like to keep the geometry as it is, but to merge all the components in only one file.

I thank you in advance,

Best regards,
