Hello,

I have a solidworks assembly file that contains subassemblies. I'ved tried bringing it into a non-seq model as a CAD Soldworks Assembly but get the following error: 'File must represent a SolidWorks assembly and end with the extension SLDASM.'  My file is an solidworks assembly and does end with SLDASM. To avoid this error, I've saved it as a STEP file, and have loaded it that way. The CAD file looks as it should in the NSC Shaded Model view. However, when I highlight that object and explode the CAD, several of the parts are missing. The explode dialog box does get the correct number of parts but duplicates several parts while omit others entirely. 

Is there any way to import the assembly and then explode and edit parts?

Thank you,

Nick
