ShapeScan — Convert real objects to accurate SVG/DXF with just a phone photo

3D Printing
1

Hi everyone,

I’ve been working on a tool called ShapeScan, designed for makers, CNC users, laser cutters, engineers and hobbyists.

It converts a single phone photo of an object placed on a reference sheet (A4 or US Letter) into a true-scale SVG/DXF — automatically corrected for lens distortion and perspective.

:wrench: Current capabilities

Automatic sheet + marker detection

Perspective & lens distortion correction

Clean outline extraction + curve simplification

Manual correction mode (trace on top of the rectified image)

PNG & STL export

Free to use

:test_tube: What I’m looking for

I’d love to get feedback from the maker community:

Would this be useful in your CNC / laser / workshop workflow?

Any export formats or features you’d like to see?

Any issues you face when digitizing objects?

Thanks for taking a look — feedback from other makers is extremely valuable!

There is a subreddit also if you want and the email support on the site.

Really like that you include a PDF template — big concern of course is that the default in pretty much all PDF viewers when printing is “Shrink to fit” — maybe include a note on the measurements? A further concern for accuracy is that while inkjet printers are very accurate left–right, they tend to fall a bit short vertically (biasing to ensure overlap of successive rows) — probably not an issue at these scales, but if you see a lot of reports of shortfalls along the long axis, that is likely why.

The big feature of course would be to make Gridfinity bins — a feature I’ve been looking for is an option to support an object only at the ends, so a UI for this (overlay a grid and pick which bin sections to make) would be very interesting.

Just sent the template to my (laser/paper) printer, and will try to find time to experiment.
