I am trying to create an internal flow region for my motor cooling jacket, however, when I attempt to select my seed surface which is the internal helical sweep, I can only select part of it and not the full sweep. I’ve tried imprint and union but neither helps. If someone could help me out this that would be much appreciated.
The project has three geometries, please inspect the copy geometry as this is an stp file.
I’ve attached an image of what i am trying to achieve as I have managed to do this previously.
