As I said earlier in thread, there are alternative options; BricsCAD, IntelliCAD, NanoCAD, DraftSight (no longer free) and I recently tried one called ActCAD (built on intellicad) that wasn't bad. I mean $50/month for LT is not bad but after a few months you could have bought one of the CAD clones. Worth looking into /shrug
If your son is in school and has a school e-mail address he can use ANY AutoDesk product for free, to learn on. Just saying
