Environment: Microstation V8i SS4, 08.11.09.833
Following situation:
I have got a polygon that represents the half of a double pitch roof (saddle roof). The pictures below show the polygon and a 3D-view of the roof as well:
Now I need to place a beam onto the polygon so that the beam is lying "flush" (hope that this expression is okay here ...) - the next picture shows the beam as it should be in red:
Unfortunately the beam is placed like the green rectangle ...
The beam is placed by supplying a start and an end point. Moreover you can specify a rotation angle to rotate the beam along the axis.
The green rectangle is constructed with 0° rotation angle - the red one has got an angle of 23,3121°.
Unfortunately I am not able to find a way how to calculate the correct rotation.
I have got the following details:
I have attached a .dgn-file that shows the situation ...
Test_2.dgn
Does anyone have a clue how to calculate the rotation angle of the beam?
I am running out of ideas ...
