Hope you’re all doing well. I’ve been having trouble creating a parting line and surface for my model, which has been preventing me creating the core and cavity. I was wondering if anyone could assist me in learning how to do this in Rhino? I watched the tutorial videos, but still had no luck with it using my model. I attached it to this post.
Thank you in advance!!

As pascal noted above, once you create your draft curves, you will use the new _RibbonOffset tool-
this will allow you to create the curves you will need to make your shutoff collar. Once you have your parting line and the offset, 2 rail sweep can be used to create the actual shutoff surface itself.
then it’s a matter of blending this surface into your mold halves-
see this video
and this simple video with the basic steps outlines-
Thank you! the parting line looks great! Unfortunately, when I try to use the ribon offset it does not allow me to select the new curve
My apologies. I am very new to Rhino
no worries, make sure your parting line curve is closed before running ribbon offset.
also note, you have some undercuts that need to be fixed-
Thank you for the response! That’s what I’ve been trying to do, but unfortunately, it doesn’t seem to allow me to select more than 1 edge on the piece
send your file to support@mcneel.com or post it here, I’d be happy to take a peek and see what’s missing…
