I have been playing around with some diagrams for the recent train pavilion design. The architecture diagrams that I create on this site have ranged quite a bit over the years. Lately, I have been gravitating towards a minimal approach for these types of illustrations. For this series, I experimented with creating a dialect between plan views and corresponding perspectives. I used a simple color palette to help relate and orient the viewer within the diagrams.
All these diagrams were created using a Sketchup model rendered as a clay model in V-Ray. I then used that clay model as a base in Photoshop to apply color. To see some more diagrams that I have done in the past, I have added some links below which go into more depth on the workflow that I use:
