Hi, I have a problem with the origin orientation of assemblies created. This orientation is affecting all the assemblies views created because the elevations and plan views will not align with the elements main face(normal). Is there a way in dynamo to get the origin and alight the orientation with…

Hi @john1 / @MJB-online , Sure is possible, here is a python script I quickly threw together that allows you specify the rotation (in degrees)… import clr import math clr.AddReference("ProtoGeometry") from Autodesk.DesignScript.Geometry import * clr.AddReference("RevitServices") import RevitServices…

Hi John, This is a very interesting topic. I really hope this can be done by Dynamo (a little Python magic maybe). If the rotation of the elements could be added as input to the assembly (steam)nodes of @Julien_Benoit1 , would be the best option if you’d ask me. Hope someone crack’s this one. Ki…

Hi Daniel, Wow… this is great, thank you very much. An Assembly is a great tool for manufacturers who create their shopdrawings this way. And that’s why i really don’t understand the family/element rotation isn’t done by Revit on default. But this is a great way to change it afterwards. Does th…

You’re welcome @MJB-online , The script handles multiple assemblies, but list lengths for each input have to be the same, you can use the list.cycle node if you have a common input value (say the rotation axis will in most cases be the Z azis). This doesn’t automate the rotation angle, I have left …

All, For completeness (as I really didnt fully answer the Question as I was pushed for time) I have added a few additional nodes in this script to help modifying the Assemblies Transform. These include the following Post Assembly Creation Utils:- RotateOriginAboutAxis (as above) ** Rotates the …

Hi Dan, That’s even more than we wished for. Thanks a lot. I think the first is the best for me, but i certainly gone play whith the others as well. Kind regards, Mark

Cool. Glad to help. Let me know how they go :blush:

Hi all, If you don’t succeed to use the above scripts on a list of elements, you could try replacing “TransactionTaskDone” by “ForceCloseTransaction”. Or check the below topic. https://forum.dynamobim.com/t/first-attempt-editing-a-python-script/19156?u=mjb-online Kind regards, Mark

Hey Daniel, The scripts all look good, but I cant get the last one to work or maybe I don’t quite understand what it does yet. I did get the rotate around axis one to work Does the last script look at the element and give the assembly the same rotation as the element ? If so , if your element-inpu…

Hi Daniel, I’ve used your node (RotateOriginAboutAxis) and it helps a lot, but know I stumbled across a problem where it looks like the set rotation isnt rotating along the assemblies location point. So the assembly-origin is rotated but is not in the same place, which means the section A and secti…
