I am trying to trim the far half (as shown) away from this pipe with the orange lines.
I initially had just the two long orange lines, made sure they went beyond the ends, trim failed.
Now I add two short segments at the ends using Int on the orange lines and circular end to complete the trim line if that is the cause, still trim fails.
It is possible to trim a solid with a line, tested a box.
The orange lines were created by projecting lines and curves onto the pipe so they are in contact, furthermore I ran intersect and they intersect,
Cant think of any other thing.
So frustrating when the above seems an ok approach to ensure all is ok.
Always some minute microscopic thing causes an hour of problem solving.
