Hi @Bencjaminn,

The ESRI.lib is set to read-only.

If you intend to customize one of the rules from ESRI.lib it's recommended to copy it into a separate project, edit the rule there and then re-assign the shapes with your edited rule.

Hope this helps!

Best
Jonas

hi again, in the example of the Building_From_Footprint rule it's not so trivial, because when you set it to textured the facade will be just a single rectangular shape there is no further tiling done. So you need either to add an intermediate rule where you do the tiling first or you edit the schematic facade variant where the facade is tiled into walls / windows. To better understand how the rules work I suggest you to work with the Model Hierarchy (See attached screenshots)

Tutorial 6, which shows how to create a textured building facade with windows, might be of interest.
