I am working on an impeller and I am trying to extract the core from the model but I cannot get the tooling split to save my life. It jsut keeps saying that it can't knit the surfaces.
I tried using the STEP in and out method but that didn't work either.
I realize that I am using a machined model but the internal is the same as the as cast (which has an odd parting line, which I might have screwed up). The draft is correct in the model and should not be changed.
