I have been in the Architectural Drafting field for over 12 years. I have used AutoCad exclusively throughout my jobs so far, but have an offer and that firm uses Archicad. I never heard of Archicad until I interviewed with them. How frustrating am I going to find Archicad to use? Will I like it or will I hate the new job and find one that uses AutoCad? Any help is greatly appreciated.
