Applying slopes to a flat roof with a variable layer

Hi,

 

I am wondering is it possible to generate the ridge and valley lines on a 'flat' roof by means of entering a given slope and direction from the perimeter edges or preferably ridge locations? I am pretty aware of the means of adding split lines and modifying sub-elements but would like to know if the above or similar method is available for use over calculating multiple heights. I have multiple roofs intersecting where the ridge heights are the dictating factor and the low points to the perimeter edges vary in distance from ridge, sample image:

What technique would you use?

Sounds like you are saying that the ridge height and location is fixed and therefore determines the plate heights. I would use Modify Sub-Elements myself, but an alternative would be to determine the plate heights before entering  Roof sketch mode. Those plate height values determine the line segments' Offset From Roof Base value inside Roof sketch mode.  You could always use Modify Sub-Elements as an means to determine plate heights and then create a "regular" Roof using those those values to set the Offset From Roof Bases.   

 

...wait a minute. Are all the slopes the same?  I was thinking they were.  If plate heights are the same around perimeter, then you would still need to determine the pitches before sketching the Roof.  Modify Sub-Elements would be the easiest way to find pitches, IMO.

Modify sub elements, add ridge lines and change their elevation.

You know, I just noticed that the title is "Applying slopes to a flat roof with a variable layer".  You have no choice but to use Modify Sub-Elements in this case. But why would you model a roof this way?

Thanks for your input.
The reason for the variable layer is because it's a 'flat roof'.
Looks like the only logical option is to work out the actual point heights. Adding split lines will also help.
thank you again.
