[alt.sources.wanted] CAD system wanted

envwpk@epb2.lbl.gov (Werner P. Keilholz) (05/25/90)

My group is working on an infiltration modell to simulate
the energy performance of buildings.

To make the input and output to this simulation model more
user-friendly, we are interested in including a 2D CAD
system.

Such a system should allow interactive input of elements that
occur in a floorplan, such as walls, doors, windows, etc.
It would be advantagous if the system allowed to assign 
values to the various graphical objects.
The software should also provide output in a numerical form that
can be further processed by other programs.

Does anyone know about software that realizes such
functions on a PC ?  Freeware prefered, but we might also
be able to invest a limited amount of money in a comercial 
product. 

Please reply via e-mail, as I usually do not read this group.

Thanks in advance,

Werner Keilholz
