Hello all, I am trying to rotate an elevation marker. I have looked up many forum post on here as well as the ever popular Module 2 . Module 2 got me close but I was not able to achieve what I wanted to do with it. The Python script was doing to much at once. I then found Rotate Family in archi-lab …

After hours and hours of trying to figure this out I finally got it to work. The code I provided above and the archi-lab Rotate Family nodes both work. The problem was not with the code but that you cannot rotate an elevation marker without a view on it. Yep thats it just make sure you have at leas…

awilliams, Thank you for your reply. I am very new to python and gave it my best shot but cannot figure it out. I tried adding UnwrapElement(IN[1]).ToRevitType() to my code but I get the err "Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed. Traceback (most recent call last)…

After a lot more tinkering and looking at code examples. I got the script to export the elevations markers with no warnings. It does not however rotate them. I am at a loss. import clr import math clr.AddReference('RevitAPI') import Autodesk from Autodesk.Revit.DB import * clr.AddReference('Revit…

Hi Steven. I’m trying to do exactly the same, and got the same problem. Always null even with an active view. Please may you share your graph?

@franciscusm Would you be able to post a screen shot of what your graph looks like and the problem that you are having. My graph has a bunch of other stuff in it and this could be a great learning opportunity for you and others looking at this post. The Python script and the archi-lab node work di…

Sure, the graph is a bit messy because it’s WiP, but the idea is select a section marker and select a wall to look at. It’s currently using the Archi-Lab node, but tried also the Python code in this post and another node I don’t remember with no joy, always null. Tried both radians and grads and s…

I think you just need to turn you Elevation marker into a list. Orange group in my picture. This worked for me. Similar work flow to what you have. I used the Python I posted above. [Capture]

Steven, Thanks man. Your python code works, just needed to put Elevation Marker and Angle in lists. BTW have you noticed that the View’s ID is always the Marker’s ID +1 ? It’s very helpful.

It works, however the rotated angle makes no sense at all. Even if I try to rotate it only 1 degree it rotates circa 90 :hushed:

You are right mine does not work. I am not sure why though. Try this out. Arch-lab node does not work when bundled (not sure what thats about). The last Python is the code provided in Rotate Family. The first Python is pulled from my code above. You can not place a BBox around a marker so I used t…

It seems to work right when rotating 90 degrees but not when rotating a random angle. The same happened with the previous graph. I can’t find a pattern or a reason. It’s really strange. The axis seems to be just a perpendicular line to the floor plane in all cases so that shouldn’t be the issue, it…
