I recently watched a SIG presentation where the presenter was using a parent /child relationship to turn off/on the proposed median. I have always used display rules to do this. I was curious if anyone knew if there was advantage to doing it with the parent/child relationship as opposed to doing it with display rules. Maybe one uses more memory than the other? Thanks Brian
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.

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.
Thanks Chris
