I am currently a student and have registered via the AutoCAD site for a student version of AutoCAD. The last release I bought (full version) was R9 but it's quite out of date. I'm using only AutoSketch Release 7 just now and I'm finding it really slow compared to using full blown AutoCAD. Before I wire off the funds to the reseller for the software (2005) and user manual(s) What are the functionality restrictions of the student version?
