I found a great program in AUTOCAD somewhere called EXPERT2010. It was obviously written in Poland and I would guess acquired by Autodesk. I had to reformat my computer and when I reinstall all the packages I thought I had, but I can not find Expert2010. it was in an a folder called other tools. The program is for the design of speciality structures such as retaining walls.
Any idea where to find it, this program was really great and I wanted to use it with my classes.
