CADProps — The Complete Guide: Volume, Weight and Dimensions of a CAD File Right in the Browser
A supplier sends you a STEP file or a SolidWorks part and you need its weight, volume or overall size — without opening a CAD program. CADProps does exactly that in the browser: upload a file, see the model in 3D, and the side panel shows the bounding box, solid volume, surface area and mass from a density you choose.

CADProps
Open STEP, IGES, SolidWorks and more in the browser and measure dimensions, volume, surface area and weight — free, no install, no account.
Get it from the vendorWhat you get
- Over 55 formats — STEP, IGES and Parasolid as exact geometry, plus SolidWorks, Inventor, CATIA, NX, Solid Edge, STL, OBJ and DWG/DXF.
- Volume, area and weight — computed from the geometry, with a material choice (steel, aluminium and more) and a warning when the body is not closed.
- Measurements — edge length, face area, hole diameter, distance, angle and coordinates.
- Section, explode and compare — cut the model, explode an assembly and compare two versions.
- Convert and share — convert to another format and create a view link, with a free account.
What to know before you upload
Files are sent to the CADProps server for processing, so this is not the tool for confidential client drawings. For viewing that stays entirely on your computer, use Online 3D Viewer. Volume and weight are exact only for a valid closed solid, and the density is your own assumption — check it against the material specification. It is a new, independent service with ads on some pages; guest files are deleted after about an hour.
