Hi, how are you? We can model house from attached .pdf without problem. It is impossible to attach files with proposal but check our portfolio, all those house models are modeled firstly using AutoCAD, then materials are applied using 3ds Max, etc... We are team of only regular degree and master degree architects and great, very experienced designers with experiences in practice since 2006. I invite you to have a chat with me to discuss your project (if i work at the moment please have patience, will be with you soon). Best regards! Boris from Novi Sad
