Taking a Removed Swept Volume, Turning into NEW solid part?

APynckel

I have this part that I've created. It's a 1 to 2x adapter/reducer fitting I'd like to cast in Aluminum. I'd like to take the negative volume Y inside of it, and make a new part from it (casting purposes). It would be to make a "core" for the casting. Is that possible?

yep. there are a few ways. Without access to your model i'm not sure which would be most straight forward. Here's how I'd approach it from scratch (some techniques here are for modeling speed, but you might need more accuracy or control). https://cad.onshape.com/documents/99de8eeeaf6ea653de091b85/w/0b6a024ef447bd99665d53bc/e/00d4b678e42db98b1019e6e4


If you're pretty far along, as I assume you are, then consider using the Offset Surface tool set to 0mm to copy the inner faces, then use Fill Surface to cap it off and make it solid.
