About.sldasm

A SLDASM file is a SOLIDWORKS assembly: parts positioned by the mates that constrain them. Sent with its SLDPRT files, the whole product converts as one and component names are kept. An assembly that stores its components’ shapes converts on its own too, every component placed where it sits — as a mesh, or as a solid whose surfaces are rebuilt from those stored shapes.

Someone sent you a whole product and you need it in a neutral format your CAD system, renderer or printer takes.

Questions5 answered
How do I open a SLDASM file?
Drop it on this page. It opens in the browser with nothing installed and no CAD licence, and converts to any format below.
Is it free?
Yes — 5 conversions a day with no account, 2 of them to solid formats like STEP. A free account raises both, to 4 solid conversions a day, and adds 25 credits.
Do you keep my SLDASM files?
Without an account, the upload and the result are deleted within 24 hours. With an account, both stay in your files until you delete them; deleted files leave our servers within 24 hours.
What can a SLDASM file be converted to?
Every format listed on this page — each one is a conversion that completes.
Can I get the geometry back into CAD?
Yes. Convert to STEP, which Fusion 360, Inventor, Onshape, SOLIDWORKS, Creo and FreeCAD open directly — usually with the part's own surfaces, and it says when they had to be rebuilt.
