This was a architecture walkthrough that I did with Revit regardless of the Lewisville project that I worked on as a freelance project. It is 2500 frames and the rendering took a couple hours just to do hidden line. I am using an hp computer HP computer , quad core (64 bit), (really powerful computer for what it's worth)inter core i7 processor, with a nice nvidia graphics card (2 GB dedicated ), memory of 16 GB, 1 TB hard drive. I was glad my computer could handle and process everything that I was designing. I remember before when I had a different computer and all I could see was wire frames when I would render a walkthrough. Next, I will be rendering it with 3DS MAX DESIGN and VRAY.
