Ever wonder why your 3dm is so big? Files can get out-of-hand when collaborating on large architectural, marine, or fabrication projects. Find your file’s “baggage” with Audit3dmFile ’s interactive visualization:

The Audit3dmFile command presents an interactive “tree map” visualization showing the relative size of objects in the file. Audit3dmFile allows you to see which objects (or data!) take up the most space on disk. Once identified, you can use the tree map (or the list) to select the object in Rhino.
