I was wondering whether the first connector determines where the seam of a closed, smooth surface is going to lie?
I have honestly never had problems with this but if I know I can put the seam somewhere out of the way, I might as well take advantage of being able to.
Do you have an example of the seam you are talking about?
Not.. really.. because Solidworks doesn't show them!!
But I know some modeling packages have trouble or need to do extra calculations to handle with the place where a smooth closed surface comes back into itself (the seam) it's like an invisible smooth edge, like if you fold a sheet of paper in a cylindrical shape and tape it together, where the tape would be is the seam of the surface.
Not that I think I've ever had to worry about it in Solidworks, but if I know it's where my first sketch is I might decide not to put it in a region where it'll have a lot of fillets and trimmed regions running all around and over it, just in case.
Ok, I have spent some more time with it and, the first profile used in a loft or boundary that is closed will become the seam.
