Hi, I am not doing any buildings right now.! BUT a couple of architect friends of mine are starting a company to make 3D models from architects drawings. Their idea is that I could then take these images and animate them into walk-throughs and fly-bys. They are mainly concerned with large projects, like airports. Some of their work will be for competitions. I would like to get some idea of what I'm in for. Which software to use? How much work there is in re-applying textures etc. since I understand that DXF files do not contain texture information. What sort of things do you do? Ken
