VectorWorks ->gbXML -> DesignBuilder in Architecture Posted February 27, 2010 I am still using VW Designer 2009. It has features enough for me and my practice. I really don?t need 2010. There are other priorities inside Vectorworks.....for example to really describe each layer of a wall, and also for floors and roofs.....to have a database descriptions of each of these materials. etc.etc. I will not buy any kind of upgrade, till the day I can really make use of all this BIM information it takes so long to create, and being able to do serious thermal simulations of my Sustainable designs, using Passive Solar design technics. And if NNA will take to long to solve it, I will probably have to move to ArchiCAD.
