Hi, i use revit 2016 and Dynamo 1.2.  
I need to get the height of the roof structure for different roof types.

I have the “Maximum Ridge Height” and the “Slope”.

In the end i try to calculate the eaves height.

Any ideas how i can accomplish  
this?

Give the _BondingBox_ a try  
You should be able to then extract the Max and Min points, the Z coordinates of which should help you obtain the height
