Hi,
Yes, those are the things I would like to do. I would like to see a couple of other site shaping tools as well but advanced conrol for road sloping would be on top of my list.
The main reason for us to purchase Vectorworks Landmark was that we need an application which can save site models to IFC format and our current design application (Microstation CAD & Terra Model) can't do that. I used to export site models in dwg format but demand for IFC models is increasing all the time.
I was hoping that we could do at least some part of site modeling in Vectorworks but site design tools are so limited that I am afraid that we have to continue site modeling with Microstation & Terra Model and just export the model to IFC with Landmark.
