Elevation Marker to face direction of a Vector

[jonny.pye]

Does anybody know how I might get an Elevation (Marker) to face the direction of a Vector. They seem like fickle things Elevation markers, I have tried everything to try to get them to face a particular direction including several resources that use Python to no avail.

I have found that they need to have a view activated to rotate so that hurdle is over.

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,

Yea I’ve been muddling through rotation and so was more in the game for a vector based direction but given the difficulty in rotating them I’m probably looking for bigfoot at this point. They seem like a can of worms these elevation markers.
