Hi Jeff. This is really wonderful. Thanks. [/quote]

no problem

When I do the sweep (and resulting boolean split), I am still taking a very small amount off the the end of the outward swooping part.

I have tried lowering the arc, but that seems to result in the boolean split failing (as the solid and polysurface do not full. And I have tried adjusting where the bisector occurs and how far offset the cross of the sweep is. None give me the results I am seeking. [/quote]

the first point of the arc needs to be exactly on the profile curve that you’ll be sweeping (the curve which was offset earlier)… if the profile isn’t intersecting the curve to sweep along, there will be a gap between the swept surface and the curve to sweep along… which will result in the problem you’re having.

when using Arc -> Tangent, make sure to click your first point at the exact intersection… prior to clicking the second point, use the option “From first point”… this will stop the tangent arc from sliding up&down the vertical line… it will be securely locked to the first point clicked.

that bisecting part is moreOrLess an arbitrary point to draw the vertical line at… i showed that in the video since it was where toby’s point was placed. (and i’m not even sure how he arrived at that being the point… maybe it just happened to be at an exact bisection of the angle…)

but using the bisector option allows you to easily split an angle into two equal halves:
