Free Browser-Based STEP/STP Viewer for Quick CAD Inspection

[cadprops]

Hi everyone,

We're building CADProps, a free browser-based tool for quickly opening and inspecting STEP/STP files without installing a full CAD package.

It's aimed at mechanical engineers, CNC users, and manufacturing teams who need a fast way to check model geometry before quoting or production:

Full disclosure: CADProps is our tool. We're still improving it, so feedback on real-world STEP files—especially large or complex models—would be very useful.

Is this a free service?

Great work！！！

From a purely three-dimensional cross-sectional view, unlike the closed cross-sections of conventional three-dimensional software such as SketchUp, if the cut section after this trimming can be sealed off reasonably, it is at least visually more in line with intuition.
