How would I go about creating a new body from just exterior surfaces? I created this model with a lot of complicated geometries, but when I am exporting it as an STL, the object exports with all of the interior geometries and would prefer the whole thing be a solid object. Is there a simple way to do this? Thanks!

Hi,

You need to Union them, so they become one solid part.
