Types of Files

In SOLIDWORKS, you can open any number of part, assembly, or drawing documents at the same time:

Part (.sldprt) surfacereplaceafter.gif
Assembly (.sldasm) u-joint-assembly.gif
Drawing (.slddrw) drw_cabinet_smaller.gif

SOLIDWORKS gives the three basic file types their own extensions to facilitate finding and filtering files based on content.

From an active document, you can open related files as follows:
  • Open a drawing from its associated part or assembly document
  • Open a part or assembly document from a drawing view
  • Open a part from the component in its assembly document

Typically, you begin in a part document, creating a part. When you have several parts, you can assemble them in an assembly document. You can create drawings from both parts and assemblies.
