How to setup (Cycles) rendering architectural line+shadow drawings like image above?
Duplicate all the objects to two layers (the 1st layer will be used for shadows, the 2nd one – for Freestyle lines). Light objects may be duplicated too or made visible to both layers. Activate Freestyle rendering option. Assign all the objects in the Shadow layer a simple white diffuse material; in the Freestyle one – a simple transparent one (fully white). Create two Render Layers (the 1st one – for shadows, the 2nd one – for Freestyle lines). Activate Shadow Pass in the Shadow Render Layer. Render and combine both images in Compositor. See the .blend file attached.
