Dynamo bounding box

[nagybela2000]

Hi there, I have a problem where I want to create a bounding rectangle around the doors in a Revit file. I’ve more or less managed to do that, but unfortunately, the coordinate system doesn’t match. Could you possibly help with what might be worth doing?Additionally, these solids are not being placed in Revit as generic models.

Hi @nagybela2000 

    Bounding box is always parallel to Internal Co-Ordinate system. In image created bounding boxes are correct.

If you need an angled bounding box, then take basis of the family instance and need to create our bounding box by computing geometry.

Hope this will Helps 🙂

Hey!

Dynamo geometry is different from Revit model elements. One is abstract object like a line or a point while other can be described on real world like walls or floors. To make Dynamo geometry touchable in Revit environment you can use ImportInstance.ByGeometry node.

Dynamo now has a node for "BoundingBox.ByMinimumVolume" which is handy for non-axis aligned bounding boxes.
Minimum Volume:

vs Typical Axis Aligned Bounding Box:

I managed to solve it, thank you for your help. My next question is how can I reduce the size of these rectangular prisms by 1-1-1 cm?
