Split/Trim with not intersecting curves in orthogonal views?

Hey guys, thought this would work. Is this different from previous versions? Thank you!

A thousand pictures says less than one word.

Trim will work with non-intersecting curves if ApparentIntersections=Yes. Split has never allowed apparent intersections, so there need to be real intersections found for Split to work.

Hi Hannes

Looks like splitting by curves in parallel views works for surfaces but not for curves.
IIRC, this is also what happened in Rhino 5.

Actually I don’t know why it has to work this way …

Yep, been multiple discussions about this in the past…

ep, been multiple discussions about this in the past…

So why not implementing this? Would be much fun

Here are some discussions you can peruse at your leisure…

Split >Apparent Intersections

Can someone remind me of the actual reason(s) that Split doesn’t have an “Apparent Intersections” option (while Trim does)? Thx, --Mitch

Trim / split inconsistency

I attach a very simple file which demonstrates this, but in words the problem is this: An extrusion can be split or trimmed with a line regardless of where the line is as long as it crosses the extrusion in the viewport used for the command. A 2D entity however, can be trimmed as above, but it can’t be split if the line is not actually intersecting the entity. Why? It drives me nuts, especially as I can see no logical reason why it should be so…?? It just feels like an oversight that both the…

There are older ones too, going back to old newsgroup days…

Wow this is the science behind the magic. Thanks a lot Mitch for putting in the links. Hannes @Helvetosaur
