I wish the Roof Pivot direction could be obtained and used in GDL. I currently have a LABEL that reads the roof slope and displays and pitch arrow, but there is no parameter to tell it to rotate to be perpendicular the pivot line.
I don't expect many votes here, but would be handy. (I'd actually give the object away if GS could update the GDL spec)
I like what it does but I am already using labels to display roof ID. I want to match up the roof surface in the roof plan with the roof ID in the schedules which also shows area, length of hips, ridge, valley, etc...
Is there another way to show a roof ID than with a label?
I've tried to solve this issue a while ago, without success.
The trouble is that the parameter that reads the roof orientation line is only accessible with "Roof Acessories", it adds a custom parameter that is called "ac_ref_coords", which consists in a matrix that reads x0, y0, x1 and y1, through wich is possible to define the angle.
The problem is that this is not a standard, that way it cannot be found in a standard tag and rotated, i could add this as an acessory, but, that would only allow me to add 1 object at a single floor, which wouldn't help much.
To show percentage is about using the result of "tan (ROOF_ANGLE)*100".
