// The tools

Three tools. Three kinds of user.

Each one is built for the software you already work in. Pick yours.

// How we work

No hype. No lock-in.

Runs on your workstation

Both add-ins work fully offline. Internet is needed to install and once every 90 days to refresh the licence. Your models never leave the machine.

Try it on a real job first

14 days, every feature, no card. If it doesn't pay for itself the first week, uninstall it.

Licensing you can explain

One licence, one computer at a time — move it between workstations yourself. Cancel anytime. Free on an educational licence.

// Field reports

From the shops running it.

"We switched from manually exporting each weldment cut list to CADshift and shaved two hours off every fabrication package. The stock optimiser alone paid for the licence in the first week."
Structural Detailer · Steel Fabrication Co. · Australia
"The PDF export with QR codes changed how we handle shop-floor paperwork. Every part sheet scans straight into our ERP — no manual data entry, no transcription errors."
Production Manager · Contract Manufacturer · New Zealand

If you draw in SOLIDWORKS, CADshift for SOLIDWORKS. If you draw in Autodesk Inventor, CADshift for Inventor. If you work with geospatial data and need it in another format, GeoConvert. They are separate products with separate licences.

Yes, on all three. The SOLIDWORKS add-in keeps its free features after the 14-day trial. The Inventor command palette is free forever. GeoConvert gives you 2 free conversions up to 512 KB each, then charges per conversion.

The add-ins run entirely on your workstation and work offline; an internet connection is only used to install and to refresh the licence every 90 days. GeoConvert is a web app: the file you upload is converted on our server and handed back to you.

SOLIDWORKS 2018 and newer desktop versions (not 3DEXPERIENCE), and Autodesk Inventor 2025 and newer on Windows.

Yes. Unregister the machine from your account and activate on the next one. One licence, one computer at a time.

Yes. Cancel from your account and keep access for the rest of the billing period you have already paid for.
