Convert SLDASM
to OBJ.

Updated 2026-10-19

To convert SLDASM (.sldasm) to OBJ (.obj), drop the file below and download the result, in the browser with nothing installed. The part opens and comes back as a OBJ mesh, with nothing installed.

5 conversions a day with no account. No card, no install, no CAD licence.

ResultTessellated

The solid in the SLDASM file is triangulated to produce the OBJ output. Assemblies convert whole, and components keep their names.

HowThree steps
  1. Drop your .sldasm file above — up to 200 MB without an account.
  2. OBJ is already selected as the output.
  3. Download the .obj. Without an account, files are deleted within 24 hours; signed in, they are kept until you delete them.
FormatsWhat you are holding

SOLIDWORKS assembly file (.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.

Wavefront OBJ file (.obj)

OBJ is a plain-text mesh format from graphics. Unlike STL it keeps named groups, texture coordinates, materials and polygon faces, which makes it the usual handover into rendering and texturing tools. It is still a mesh, not a solid.

The destination is a renderer, game engine, texturing tool or visualisation pipeline.

Questions7 answered
Is the SLDASM to OBJ converter free?
Yes. 5 conversions a day with no account and no card. A free account raises the limit and adds 25 credits.
Do I need SOLIDWORKS to convert a SLDASM file?
No. The file opens and converts in the browser with nothing installed and no CAD licence.
How accurate is the OBJ mesh?
The part opens and comes back as a OBJ mesh, with nothing installed. The solid in the SLDASM file is triangulated to produce the OBJ output. Assemblies convert whole, and components keep their names.
Do assemblies convert, or only single parts?
Assemblies convert whole, and components keep their names. Send the part files too — an assembly alone has no geometry. Over 5 parts needs an account.
How big a file can I convert?
To a mesh format like STL: 300 MB with a free account, 200 MB without one. To STEP, Parasolid or SLDPRT: 140 MB, because rebuilding a solid takes about twice the memory of writing a mesh. Maker and Studio convert up to 830 MB and 380 MB — a large conversion on a paid plan gets the server to itself.
Is it safe to upload my SLDASM file?
Files travel encrypted and are processed by machine on our own servers — no third parties, no ads or trackers, no AI training.
Is my SLDASM file deleted after converting?
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.
Beyond convertingSame file, four workspaces

Keep the part open: fill it with a lattice, check it with FEA, texture a surface, or slice it into cut-ready sheets. These workspaces are in early access — create an account, then apply from inside the app.
