Hello,

I’m experiencing some issues lofting a set of curves to produce a smooth surface. I’m working with two sets of three curves. The first set is troublesome. These curves are offset 10mm, and one set of the curves refuses to loft smoothly; it’s as if the curve-start begins at one point then jumps right next to the endpoint before continuing normally, but the seams are nearly in line with each other (see pictures).

However, the second set of offset curves (distance 30mm) lofts beautifully into a polysurface made of two surfaces, as intended. Not sure why this particular distance works, since both sets of curves have the same direction/orientation and the seams are awfully close to lying on a line. Precision is paramount, so I’m not interested in smoothing these curves. I can adjust the seams such, but I’m not sure that’s the problem and I feel like there is a fix somewhere internal to GH.
