I am a high end residential architect who's main expertise is drafting with Archicad. I can provide renderings with the help of Artlantis and I am highly interested in your project. Ive been working in Archicad for 3+ years, I am able to create my own GDL objects, and I am in constant contact with graphisoft vendors in my area. I will pm you some of the renderings I have been able to create, Hope to work with you in the near future!
