New Custom Tool : SVG to Sketch
Hey all — long-time Onshape user, wanted to share something I've been building and using in production.
The problem: Getting vector artwork (logos, cutout profiles, panel designs, icons) into Onshape as real, editable sketch geometry is annoying. DXF import can be inconsistent, and manually retracing SVGs with the sketch tools is a time sink.
What I built: A web tool that takes an SVG file and converts it into native Onshape sketch entities — proper lines, arcs, and fitted splines — using a custom FeatureScript feature under the hood. It's not a raster/image import or a dumb flattened curve; it comes in as real sketch geometry you can constrain and edit normally.
Features:
- Upload SVG → get native sketch geometry in your Part Studio
- Target width parameter to scale on import
- Drag manipulators for X/Y position, rotation, and scale — right in the sketch, no re-import needed to reposition
- Currently extending it to accept raster images (PNG/JPG) too, via an image-to-vector preprocessing step
Status: It's fully functional and I use it daily, but it hasn't been approved on the Onshape App Store yet. So for now it's a standalone external web app you use alongside Onshape rather than an in-app extension.
Custom Tool need to be added : https://cad.onshape.com/documents/c201c83c91a83aade27337d1/v/fa88b35f1753d1f6f757a891/e/09d98a5bdcf6272e418d3ec2

You'll need your Onshape document/workspace/element IDs (visible in your document URL) to point the tool at the right place.
Happy to answer questions about the workflow, limitations, or what it can/can't handle geometry-wise. Feedback welcome — especially edge cases that break it.

SVG import is much needed. Looking forward to testing this out.
I'm curious why you need an external App to do this? I had Codex write some SVG import code for my Origami fold feature.
Granted, I have not expanded the SVG import functionality to handle as many entities, but it seems like it's quite possible to do it all with FeatureScript. I may get back to trying to do just that.

Hi Simon,
Thanks for testing my tool and i love your custom tools much.
Well the external app is added to convert the svg to sketches. I have already contacted the onshape support but no response received to make it work inside onshape document.
For testing purpose, i have kept it external + need a manual connecting to import to onshape.
And onshape do not do the conversion process, i used the external app that helps. At the same time, i do not want to spend tokens just for conversion and not all users know about this conversion.
Everyone wants the work do be done simple and fast. So i introduced it based on frustrated experience in drawing logo's manually.
If you dont mind, do you have any idea of, how often or fast onshape can approve my application ?0
