CADProps

Receiving a CAD file doesn't always mean you have the software that created it. CADProps offers a browser-based place to inspect supported models, check their dimensions, and calculate properties such as volume and surface area. A product team reviewing a supplier's model could use that information to check the part's size and units before discussing the handoff.

The public site lists STEP, SolidWorks, NX, CATIA, and several mesh formats among its supported inputs. Viewing and measurement don't require an account. Conversion, saving files, and creating share links require sign-in. No model was uploaded for this note, so import quality and measurement accuracy haven't been tested.

CADProps distinguishes between solid geometry and a mesh made of triangles. That distinction matters more than the length of its format list. The site describes mesh measurements as approximate, while solid-volume calculations depend on valid geometry. A weight estimate also needs the material density you supply. An incorrect unit or density can make a precise-looking number misleading.

The useful role here is an initial inspection. Before using a result for an engineering decision, check the source file, units, and which parts the calculation includes.

CADProps processes and stores files on U.S. servers. Its privacy policy, updated October 8, 2026, says guest files, previews and calculated results are automatically deleted about one hour after upload. The workspace shows the deadline. A guest can remove files earlier through the file menu or by clearing the temporary workspace.

For files saved to an account, the policy sets a 90-day expiry after the owner's last use. Opening a saved file or downloading its original starts a new 90-day period. Viewing the file list or opening a share link does not reset that period. Deleting a saved source also removes its online results and disables its share links. Share links otherwise expire after the selected seven or 30 days and can be stopped earlier.

These are the published retention rules, not deletion behavior tested for this note. For confidential designs, check whether your team permits uploading to and storing files on these servers before using a supplier's model or an unreleased part.

Updated October 9, 2026. The retention description now reflects the October 8 privacy policy. The September 27 description reflected the previous policy.
