I imported a large 62mb model made up of many blocks. I can live without some of the block elements. Knowing the size could help me decide which to delete. I could not find this info in Block Manager, Properties, or What. Is there a command that lists the size of blocks in a model?

Hello - are you looking for size as in memory use? -Pascal

No. As relates to file size. e.g. If a model has 3 blocks and is a file size of 10mb, but deleting one of the blocks and purging it reduces the model file to 1mb. Where can I find the size info of the block, other than exporting it as it own model and reading that.

Hello - see if the attached script does you any good - To use the Python script use RunPythonScript, or a macro: _-RunPythonScript "Full path to py file inside double-quotes" BigBlock.py (992 Bytes) @CalypsoArt - updated to show a ranking… -Pascal

Thanks Pascal. The script did return a suggestion of the largest block which is helpful. I expect it is more difficult to do than I think, but It would be good to know the sizes for comparison. (I had assumed that data was readily available in the .3dm file) Here’s an example of why I would like i…

you can try with this one also from @pascal : [image] Rhino file - size of elements in MB Rhino for Windows @luca_biselli - in case it helps, here’s a python that will find the largest X objects (memory estimate) and mark them FindLargestObjects.py (1.3 KB) Use RunPython…

Where can I find info on the size of a block?
