Hi,
In my rotated project how can i set boundingboxes in dynamo orthogonal to the revit geometry?
Is there a node in dynamo that controls this?
eg. set my dynamo geometry orthogonal to Project Base Point, Origin(=preset) or Survey Point?
Thanks
Marcel

i have a directshape methode…

that would be i nice homework for the dynamo team! i know the game “angry birds” used 2D bounding boxings with physics … 
Bounding box by minimum volume was added in on think Revit 2023.1 or Revit 2024.
do have an example ?
Released in 2.16, see the blog post here: Dynamo Core 2.16 Release - Dynamo BIM
It’s a Dynamo node, not a Revit method.
For a Revit method you could pull the bounding box of the door symbol, and transform it by the sum of the door instance’s transforms; not an easy lift and not something I’d bother to code, as you’re better off building the clearances in the family itself, or hosting a clearance family based on the door.
The
BoundingBox.ByMinimumVolume &
Geometry.OrientedBoundingBox
nodes generate the following message in the Biomorph node
Geometry.OrientedBoundingBox
Looks like bimorph needs an update.
Hmm…
It looks up to date.
Revit 2023
If somebody would like to test… please find them attached.
Kind regards,

Yes - I don’t think Bimorph allows non-orthogonal bounding boxes.
OK, then I will proceed on @Draxl_Andreas direct shapes…
Direct shapes work!
thank for the feedback on bounding boxes and the suggestion to take a look at direct shapes.
Please find the codes I the graph, if it’s to anybody’s interest.
