Tool
Calculates a single bounding box that encloses multiple geometries
Docs for v2.1.18, the latest version.
2
What the node takes in, from wires or typed values.
Geometry
Array of geometries to include in the union bounding box
Plane
Reference plane used to orient the bounding box. Defaults to XY plane
5
What the node gives out, to wire into other nodes.
Point
Center point of the resulting bounding box
Width
Size of the bounding box along the X axis of the reference plane
Length
Size of the bounding box along the Y axis of the reference plane
Height
Size of the bounding box along the Z axis of the reference plane
Area
Surface area (for 2D) or volume projection (for 3D) of the bounding box
The Bounding Box Union node calculates the bounding box that encompasses multiple geometries at once. You can optionally provide a reference plane to compute the bounding box in a specific orientation.
It outputs the following values:
Center point of the union bounding box
Width (X direction size)
Length (Y direction size)
Height (Z direction size)
Area of the resulting bounding box surface or volume (depending on geometry types)
Works with curves, surfaces, and solids. Geometry is automatically transformed to the specified plane before measuring.
