Shadows Analysis

[Anonymous]

Has anyone work on shadow analysis with AC? I haven't use AC to do that but I have seen it in VW and kinda complicating which needed to be tweaked with Photoshop to see the existing and new shadows overlapping. I would like to hear what others have done with AC.

ArchiCAD won't differentiate between existing and proposed shadows.

However, in Photoshop, taking both new and existing shadow study views from exactly the same angle with the proposed version an overlaid layer at 30 % opacity works well.

Photoshop's "Difference" layer blending option can also identify the additional shadow component.

You can use 3D window shading, assigning different colors to the shadows, and differentiate OLD and NEW.

One way is to copy and paste into the plan window, then you can play with the shadow polygon colors as you like.

Or superimpose in PhotoShop. as Dwight said - if you render an image.
