It essentially is a replacement for a mouse, I set FreeCAD to use Blender input settings since I’m used to those. It’s one without a screen, just a USB that I use with a kickstand hub on my Deck. I picked it because it was cheaper then a screen style drawing tablet and it would help most with Blender for modeling organic sculpture. It was a simple plug-and-play, although the software to enable some extra features was available for Linux and was a snap to add. I experimented using it with FreeCAD and it’s pretty similar to using a mouse, so I don’t need both inputs taking up table space.
It’s pretty common practice to do when an inmate is going to be outside prison walls for transportation or court trips. At least in NY it is.
