Vectorizing a drawing without Live Trace
For a lasercutting project I need to vectorize a drawing I made. The problem is that I needed a drawing grid to accurately draw my image. Because of that Live tracing the scan is not possible or at the very least a hassle to work with as it will also vectorize the drawing grid. What would be the best way to vectorize the drawing on an iPad (or PC). I have an apple pencil(2nd gen) which might help...
