how can I select elements in a 3D within the range of z coordinates

In ArchiCAD 27,
how can I select elements in a 3D drawing of a building that fall within the range of z coordinates h1 to h2?

Also, how can I select elements that are part of the range?

Hi, I'd suggest you to try ACAPI_Element_CalcBounds() command to have the 3D bounding box of element, then check whether it falls into your range or not.

HTH.
