I got a degree in Architecture in 1978 from the Philippines, been working in the A&E since 1974 up to 1998 with manual production of DWGs. A little bit introduction into CAD later up to 2001 in the USA, then I stopped being employed in the field of Architecture. After almost 8 years, totally lost info about CAD, I decided to go back to my field in Architecture but because I don't have a strong foundation in CAD, I don't know where and how to start and acquire a good knowledge in CAD and be updated to its present technology, so that I can be employed again. Please help.

  Not sure which version you are getting into, but I have 2009 and in college 1st and 2nd year we used this text book..

Its an easy read not bad price, and I've used it many times since that course.

Thanks for the information. I'll try to check that out.
