First let me say getting an Arcdroid has been an adventure. Since late August when I received my Arcdroid till now, I have been trying to learn all there is with the simple trace program, Inkscape, and Sheetcam. After being totally overwhelmed, I settled on just drawing what I wanted on a piece of paper, then using the curser plotting out the holes and outline of the part. This actually worked out quite well for now.
Hopefully I will eventually learn all of the other programs, but for now I’m happy with the results.
