vs FreeCAD
Browser Alternative to FreeCAD for Viewing STEP
Open STEP files instantly when you only need to look — not remodel.
FreeCAD is powerful open-source CAD software but heavy to install and slow to launch for a quick supplier review. CADDaddy opens STEP in the browser in seconds for orbit, measure, and export.
- No 500MB install for a 30-second file check
- Share a link instead of emailing large STEP files
- Faster first paint on low-spec factory PCs
- Mobile preview for buyers on the go
