The feature rules for the COGO and Template extensions are part of the basic feature rules. See Basic Feature Rules.
The Profile extension does not use any specific feature rules.
When you add the Plot extension to a industry model, client-side Plot feature rules are created and assigned automatically to the plot feature classes (PLT_*).
Do not disable any of the Plot feature rules.
A plot can either be created using a plot template, or a blank sheet. The plot template specifies attributes that cannot be modified in the plot created from that template. Feature rules maintain conformity with the templates. A template-based plot stores the relation to the template in the PLT_PLOT.FID_PARENT_TEMPLATE attribute.
When you create or edit a plot, or a plot template, the plot features and the GIS features are drawn in the AutoCAD model space. Feature rules control any modification on a plot feature and ensure that related features are updated appropriately.
