SLDPRT viewer
Open and measure SOLIDWORKS parts without installing SOLIDWORKS.
How it works
Upload
Drop an SLDPRT file. Conversion usually takes under a minute.
Inspect
Rotate, zoom and measure the part.
Export
Create a 2D PDF or download an STL.
What you can do
No SOLIDWORKS needed
Open SLDPRT files on any modern browser.
Measure
Measure faces, edges, holes, angles and overall size.
2D drawing
Create standard views, add notes and export a PDF.
Weight
Choose a material to calculate volume and weight.
Share link
Share a 30-day browser link. No account required.
Manufacturing price
Get an instant estimate or send the part for engineering review.
Opening a SOLIDWORKS file without SOLIDWORKS
SLDPRT is the native SOLIDWORKS part format. We convert it to STEP on our servers, then open it in your browser.
You can inspect, measure, share and export the converted model.

FAQ
Is my file uploaded to FabDigit?
Yes. We upload it over an encrypted connection to open and price it. Only FabDigit and people with your share link can access it.
Can I get a price?
Yes. We price eligible parts instantly. Other parts go to an engineer for review. You can change the material, finish and quantity before ordering.
How long does a SOLIDWORKS file take to open?
Usually under a minute. Large files may take longer.
How many SOLIDWORKS files can I open?
5 native CAD files per day without an account. Sign in for more, or upload STEP instead.
Which versions of SOLIDWORKS?
Current and most older SLDPRT versions are supported.
Can I share the model?
Yes. Copy a private link that works for 30 days. No account or software is required.
Is it free?
Yes. No account or installation is required.
