Usually in the architecture world we think of renderings as sales tools or representations of the final design.  Since we work in 3D from the beginning, we create as many views as we need to help understand the details and spaces. We then generate quick renders, not worrying too much about the image quality, and draw over them digitally with an iPad Pro and Apple Pencil. While we still always start a project with our sketch books and trace, as we get into the building model this all digital work flow speeds up the process, saves resources and generates lots of feedback from our clients. In the end, we are always searching for better ways to understand and communicate the design so that the whole team can put together a better project.
