Elevation Marker to face direction of a Vector

This sort of worked for me…

Rotate Elevation Marker

This is the final version of my graph based on @Steven and @awilliams code above (thanks both). I won’t try to figure out the direction of rotation so I added an option to select it ( usually the smaller rotation is the right direction). Inputs are the Elevation Mark to rotate, the wall to look at and the elevation that will look at that wall (and the direction of rotation clockwise or not).

Rotate elevation marker inconsistent

Hi 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 b…

Hope that’s useful,
