parent/child relationship vs display rules

Thanks Chris

 I have been accused of creating frankentemplates! I do this to reduce the number of template drops created. All common components that are used repeatedly are only in the template once. When changes occur (and they always do) there is less editing taking place, reducing the opportunity for error. Charles, thanks for your input. Enjoy the discussion. 

Some people refer to this as a "FrankenTemplate" where one template fits every design instance by using a variety of point controls and/or, horizontal feature seeking. This is somewhat like GEOPAK criteria where plan view graphics controlled what the cross section drew, except this controls the 3D model that is built. This technique is often used to drop in driveways, leave gaps at intersections and apparently to draw curb and gutter or some other roadside grading.

Even in this instance, the parent/child relations simplify maintenance.

OK yes, same principal as i described but instead of manually controlling if Curb and sidewalk is on with Parametric Constraints and Point Controls. The demo in the SIG sounds like they are using Horizontal Feature seeking to determine if a curb & sidewalk is needed.

Thanks
