So i am a little step forward with my columnheads. when they are roated anywhere, i can them set back that they are parallel to to the view:
with this simple CrossVector addition:
But I need this ( the orientation to the beam):
I checked also the angles, with different operatoros (f.e. 360 - x, x- y,…) but nothing worked:
(i checked it here, i have something to do like “close the gab”)
I think the angle with the CrossVector works with the ProjectOrientation not with the FamilyInstance, so what can i do ? I found issues regarding math… …create vector field from random to a direction.
Are there a other way to get my angles?
