With the number of Autocad users that would prefer to use Vectorworks... I was hoping the response might be that Diehl Graphsoft was actively pursuing this market by contracting with developers such as Eagle Point, Geosoft, Civilsoft,PacSoft....there are lots of companies that support Autocad because they were asked to do so. Just open a Civil Engineering magazine and see all the developers.
What about intergrating structural design? Again there are lots of developers who could benefit if Diehl Graphsoft would pursue the market. You bridged the Mac/PC gap... There are several hundred thousands of Autocad users (Civil & Structural Engineers) that have no option...
