Vectorworks Landmark is a CAD application for landscape designers. Rather like gCADPlus, it saves its files in a proprietary format. The file extension is vwf (post 2008 version of Vectorworks) while gCADPlus uses .lcd. [Vectorworks Landmark costs $AUD 2945.] When exchange of data between CAD applications is required, Vectorworks can export AutoCAD dwg files and also uses a standard exchange format called DXF (Drawing Exchange Format) . If you are working with a Vectorworks Landmark designer and need a copy of their design, we recommend developing a close relationship with the designer and trial data exchange using DXF and export just that part of the design you need rather than dwg.
