Looks like the file is too large to upload here, hence why it didn't show up in my previous comment. Here's a link to the file where I host it in a cloud account: https://ln2.sync.com/dl/ea3e5f7c0/jnucurw9-xhbtu6m5-3x3nk9p8-bzxt6zpn
I definitely do not need all that internal geometry! I think that's why the file is so obnoxiously large. Does anyone have a good trick to make an object hollow? I am starting to think either I am missing some menu options in JointPushPull, or this is really not the tool to be using here.
I manipulated the surface with sandbox tools a little and found that when I pushed/pulled, it also pished/pulled the bottom surface, which I intended to be flat! I think I am down the wrong path for how I want to be working with this model...
