This is something all 3d modellers are going to face and have fun and games with !
If I am in ortho front view and draw a curve alongside the one I feel is a bit wriggly, I then look at the result in Left view and see it kicking out somewhat. So I adjust it there and notice its spoiling the shape I had in front view, then try further and improve things only maybe to discover that its not so clever in top view now !
As its a curve, and a very shallow one at that, curving out along its 125mm length by 1mm or so, not quite planar, I need to be viewing it sort of side on I guess.
I need to constrain its adjustment and movements to a planar ‘sheet’ best fitting its shape. There will also be curves in my job that wont have a planar aspect though.
There has to be best practice for working on curves in a 3D world and I need to know of those ways as I am tail chasing.
I did try for surface through points choosing either end and its middle but that surface didnt give me the right angle to set a Cplane to.
Anyway what if a curve starts off in one plane the twists to end up in another plane, no cplane would fit it.
