Lofts and Guidlines
Lofts and Guidlines
(OP)
I am trying to create a loft in the shape of a bottle with two rectangular profiles for the body and a circular profile, of the same height as the short leg of the rectangles, for the mouth. The problem is that if I just use the profiles, the circle forces the loft to bulge out between the two rectangles. I want the transition from the second rectangle to the circle to be tangent to the loft created by the two rectangles. I tried adding guide curves and that worked well in the immediate vicinity of the curve, but the loft still bulged between them.
Any suggestions to help me win the battle of the bulge?
Thanks,
Tom

Is there a problem with mirroring guide curves? Two of the curves that I was using to form the neck of the bottle were drawn on a vertical plane through the center of the bottle. I drew one of them and them mirrored it for the other and when I selected either one of the curves, I got an invalid guide curve message. My work around for the problem was to create a separate sketch for each curve, even though they are the same.
Thanks for the help.

This way just seems so much easier than going through the trouble of trying to mirror a sketch and loft. If your going to mirror the loft you might as well make the whole thing in one feature.

We have something similar - maybe more complex. It is a rectangular to round CRT shield. It's an old model now but I don't recall any problems. I think we used multiple guidecurves. Does your rectangular section have sharp corners?
