Parts Sketcher
Lay a flat part, a photo or an accurate drawing on your pen display, trace the edge with the stylus, and export a true-to-size SVG, PDF or DXF file that's ready to drop straight into LightBurn for laser cutting — no scanner, no camera calibration, no CAD skills.
See it in action
Watch a real part go from the pen display to a true-scale cut file.
How it works
1. Calibrate once
Tap two known points to lock your pen display to true millimetre scale — works with Gaomon, Wacom, Huion and XP-Pen tablets.
2. Trace the part
Trace the edge with freehand, line, point and screw-hole tools. Fix slips with the eraser and point editing, measure any line, and shrink the outline to allow for the pen tip's outside edge.
3. Export and cut
Save a true-to-size SVG, PDF or DXF and open it in LightBurn. Parts larger than your tablet? Trace them in sections with reference marks and combine them into one file.

Which pen tablets work with Parts Sketcher?
Any pen display or drawing tablet that reaches a modern browser — Parts Sketcher was built on a Gaomon PD2200 and works with Wacom, Huion, XP-Pen and UGEE displays too. You don't even need a stylus tablet: any touch screen works, including an iPad, a Windows touch laptop or an Android tablet — trace with your finger or a capacitive stylus.
What can I trace?
Any flat part, a photo of a part, or an accurate printed drawing. Gaskets, brackets, templates and mounting plates all work well.

Our story
Built Because We Needed It
PartSketcher didn't start with a big software company. It started with a guitar pickguard.
At our other business, Pickguard World, we make custom pickguards with acrylic, wood, printed designs, and a little imagination. But before we can make one, we need a drawing that fits the guitar. And sometimes that drawing simply isn't out there.
We needed a way to trace an existing pickguard and turn it into a file we could use to make a new one. The only solution we found that met our needs cost thousands of dollars—more than we could justify for that job in our small shop.
So we decided to build the program we wished we could find.
Pickguard World gave us the reason to create PartSketcher, and real projects gave us something to build it around. We're a small business, learning as we go, making things, and finding ways to compete with the bigger guys. If something we built can help someone else do the same, all the better.
