I am looking to use map data from the blender-osm addon to obtain the height of buildings.
When the buildings are generated, their Scales are set to 1 while their Dimensions contain "real-world" measurements. However, as soon as a geometry node tree is added, Dimension is zeroed out. Is there a way to capture the Dimension value (specifically, Dimension.y) and pass it to a Geometry Node?

  • $\begingroup$ Could you add a sample blend file that shows the problem? (How to add a blend file) or at least a screenshot of geometry nodes showing what is zeroed when you try to use it? I don't understand why the dimensions would be 0, but you should be able to use the bounding box node to get the actual values. $\endgroup$ Jan 24, 2022 at 1:41

enter image description hereYou could use the Attribute Statistic node and the Range output.
