Autodesk AutoCAD LT Release 1c1
Released in 1994 by Autodesk
For Windows 3.1

AutoCAD LT is a 2-D only design program targeted at casual drafting 
users. It was positioned as a lower cost offering, with fewer 
features than AutoCAD. Initially, it was intended as a replacement 
for Generic CADD - another 2D drafting tool that AutoDesk bought out 
and then abandoned.
