Materials for filled region

[simon-pasquet]

It would be convenient to be able to assign materials to filled regions for details (e.g. in Drafting Views). This idea, if implemented, would allow details to be tagged with material tags. Additionally, any changes in the material will automatically appear in the details. An option schould be available to choose whether the filled region is cut or projected.

I really like this idea.

Currently I'm using a custom rectangular legend component to show material swatches in my legends.  The legend component workflow is really designed to show project families (e.g. walls, doors) in the legend, not materials.  The workflow for creating a new swatch family type is unintuitive and makes my legends less flexible for other users.

I wouldn't convert most of my filled region types to use materials (I have four concrete materials and don't want to remember which one is on the filled region), but I would definitely use this for my legends on my building elevation sheet.
