Geometry color (Building Attribute)

Please note: This page is currently being updated.

What is the GEOMETRY_COLOR attribute?

The GEOMETRY_COLOR attribute enables the option to update the color of functions, specified by attribute, by using a Tygron Query Language (TQL) query. It actually does not overwrite the color, so removing the attribute will restore the original color of the model.

How to use the GEOMETRY_COLOR attribute

As the operation is performed by TQL, the task can be done in the Editor, with the Query Tool. More advanced users can also perform these queries through the API.
