Properties palette

When you select feature in the editor, and show Properties palette you will be able to see, amongst regular Civil 3D object properties, additional properties enabled by Site Productivity add-on.

Site Productivity feature properties

These are also referred to feature attribute data, as already mentioned. Properties can be grouped into multiple categories.

Metadata properties are read-only and give information about when object was created in the database, who is the author etc. These properties are common for all Site Productivity objects.

Other Site Productivity properties are specific to feature class definitions, and can be edited by users if not read-only.
