Visionael clone?
 

Back in the 80’s I used a UNIX software package from Visionael that had an great feature. An entity property could be specified by a calculated cell in a linked spreadsheet. For example, an L bracket could have a bend radius determined by the thickness of the material used. Enter a thickness into the spreadsheet, and the drawing changed on screen. Does anyone know of a current CADD program that will do that?
