Hi @SV1914,
Here’s something that might help you. I’ve left some simple notes for you to see what’s happening.
Summary: (1) Query your rhino objects, (2) distinguish blocks vs non-blocks, and (3) rely on bounding boxes you can evaluate—this lets you set pivots (ground planes) per bounding box as well as measure their heights:

Note/Question for you:
Your blocks are stacked boxes, which I’ve interpreted as sets of objects that belong together, so I’ve measured their heights as such (1 height per stack). Did you intend to get individual height measurements per each individual block?
Please notify.
