really nice tutorial! I wasnt able to get a smooth surface on the inside boundary @ 11:11 with out using curvature to face relation, some how I think you did it without a relation.
Hi there. Good question. The sweeps are tools used to trim the surfaces back an equal amount from each edge, before building a blend in the holes left after trimming. You can try and add a fillet, but as the tangent angle difference in between the surfaces that are being filleted/blended runs down to zero where the creases run out, it means the fillet will also run down to nothing as well. Basically the fillet chord varies based on the angle between the surfaces. The result using swept pipes results in a visually better result.
Could you explain the reason for using the tube at 14:26 and using another boundary surface after trimming that part? Is it to make it smoother at the edges??
Hi, the tube is to create a trim that is a constant distance away from the tube centre and then the boundary is the blend surface. This is to create a blend with a fairly constant chord witdth, versus using a fillet/radius which will have a variable chord distance depending on the angle between the two primary surfaces. Cheers!
