Exported Obj ends up much bigger than original?


I have an .obj of 91mb that I import to rhino, and when I then export it as an .obj again it ends up as 138mb, how come? Even if I haven’t done any changes to the model.

The reason I’m asking is because I have a bunch of quite complex .obj’s that I need to simplify through reduceMesh and then reexport. (If anyone has a good script for automating this please send it my way).

All the best

Hi Jakob - OBJ files are text files and inherently less efficient in disk space - that is apart from any difference in how the objects are represented (Surfaces in Rhino for example, turned into meshes for obj - mesh settings here will make a great deal of difference).
