I'm trying to take a basic 2D shape and scan it, convert it to .svg and import into Tinkercad. I first tried scanning as a .pdf and converting, but all Tinkercad sees is the 8.5x11 shape. Next I tried scanning as a .jpg, but it imports a distorted 3D shape.

Is there a simple way to scan with a basic desktop scanner in a format that Tinkercad will import properly?
