Hi,
V5
attached a non planar rectangle, shape has been influenced from subtle compound curve item etc.
so how best to surface it ?
If I put a vertical line in at A heading north and see it snap, it doesnt actually connect with the top line, for when I try for split command, it says not within tolerance, so how do the experts get that line to snap there, Thus no good for surfacing as it is else is it best to sweep2 the rectangle then patch the end bit ?

The aspect of line not actually meeting up with another in a £D space, especially a curvy curve, or arc, is a weak point for me, do I turn on control points and move the end of it to where it should be, do I rotate it as a whole and scale 1d it ?
needing to move its end, keep its shape, as a planar move (if its planar) so as not to alter its location but get it to meet up.
I some times run divide then surface through points, extendSrf and then intersect on the line, then at least can see where the line end should snap to, but getting it thre without upsetting its geometry and planar angle in the 3D world…need help.
I’d make a rectangular surface with the curvature you like then trim with the arc-like curve. (which, BTW, is not tangent to the shorter of the two long lines, in case it is supposed to be).
Hi, as the top and bottom lines are the curves I need, trying to create a non planar rectangle exactly following those, I guess I may as well extend the bottom one then sweep the end line along Sweep2. then afetr correcting my ooops not tan curve us that to trim the end off.
I see a shape and just try to surface it without thinking of trimming, having been warned a while ago of the perils of trim, and that the surface isnt really gone, just hiding, comes back to bite you in the bum someone said. I am now avoiding trim on surfaces.
As to my second half of the issue, I struggle to know best way to get things to meet up when not planar, a real weak point with me. Its not planar , has to be that way, but how to get things to draw from to the other, how to alter a urve which doesnt quite meet up when examined in perspective, but is the shape I want in ortho.
