I am trying to create elevations markers for each wall face of a room. I’ve been referencing this post to rotate the actual elevation markers. It is mostly working but I am finding the rotation is inconsistent.
To calculate the angle, I am constructing a line perpendicular line from the midpoint of the room boundary curves. This is all working. But as shown below, I have two elevation markers that need to be rotated 220 degrees. One of them rotates (anti-clockwise), the other I’m not sure but it is 180 degrees off. It has nothing to do with the wall direction as I am not using this information.
The only thing I can think of is that the when the initial elevation markers are created that they don’t have the same orientation (@john_pierson) .
