I currently use AutoCAD 2007 with LandFX plug in. I have used VectorWorks in the past, but it has too many drawbacks, not enough plant material, Land FX actually has different nurseries around the nation subscribe and add the plant material that they have, specs and all. The irrigation is horrible, I live in Florida, where irrigation is becoming very important, like most of the US. I am really happy with LandFX, just wish I could use them on my mac.
