Vince ,
You can open a jpg in autocad. Go to insert/raster image. You can then scale it to size you want and trace your lines.
I traced the outside profile , then used offset for the inner lines. laid out all the cross lines ,
then drew one .375 hole. Then copy the hole and paste at all the intersections.
Your jpg. pic is on layer pic.
Glad to be a help
When it comes to electronics , I 'M of no help, so I try to help where I can.
