Roof z-justification and sub-elements

[Anonymous]

I would like to see the ability to modify the z-justification and offset of roofs (and also floors). I see these as being type parameters rather than instance. This would be helpful for roofs in situations where there may be a truss heel or similar condition that causes the bottom of the roof to be different from the bearing elevation. In floors, it would allow users to create floor finishes that sit on top of the structural floor without having to modify the offset from level for all of them.

I would also like to see more flexibility with roof sub-elements. The situation of a sloping structure with built-up crickets has occurred on nearly every commercial project I've worked on, and I have yet to find a work-around that represents the roof and all of its layers accurately. What I picture is this:

• No variable layers:
  • Sub-element controls will work as they currently do.
  • Example: Flat structure with built-up rigid insulation for all roof slopes.
• One variable layer:
  • Sub-element controls at top surface will shape the variable layer as they currently do.
  • Sub-element controls will also appear at the bottom surface of the roof structure and will slope the structure.
  • Example: Sloped uniform depth structure (top and bottom chords are parallel) with built-up rigid insulation at crickets only.
• Two variable layers:
  • Sub-element controls at top surface will shape the upper variable layer.
  • Sub-element controls will also appear at the top of the lower variable layer and will shape the lower variable layer.
  • Example: Sloped variable depth structure (top and bottom chords not parallel) with built-up rigid insulation at crickets only.

The ability to combine "defines slopes" roof with "Modify Sub-Elements" would also do the trick. Defines slope could manage the bottom plane and Modify Sub-Elements to could manage the non-parallel top plane with variable thickness.  Although I am not a fan of "Modify Sub-Elements" because they tend to be time intensive and don't flex with the building like "defines slopes" roofs. I would prefer a "cricket tool" be added, that could simply define a ridge  line, its elevation and the slope for both sides. The ridge tool would only impact the variable thickness of the roof assembly.
