I used P-CAD back in the mid 80's for EE. The P-CAD system was many 
times over way more effective and professional than AutoCAD, which I 
also used for one company. Okay P-CAD also did cost near 10 times more 
than AutoCAD. I just speculate, was it too expensive or why do we not 
hear about it anymore?
