How do you split 3D curves?

@MBartlett21 did a great job with 3D Point to add points to 3D curves. And composite is great for adding curves together. How to split a 3D curve though? Hoping someone has created a FS for that.

The entities used for split do not have to intersect the curve, it just finds the nearest point. Let me know if you find any bugs.
I did some testing and it seems to fail on other types of 'created' 3D curves - examples of Bridge, Project are in the copy document here. There is an error on a surface boundary but that may be the underlying curve.
It does not seem to accept a Composite curve but I do not think that is a must since we can split the individual curves and then make new composite.
This is going to be a handy feature.
looking forward to it. I am in middle of tool design for automotive project and splitting curves is very helpful when working with imported geometry. And I hope others besides me will benefit.
btw the 'Highlight Boundary Edges' is working great. Makes all the difference while repairing models.
For composite curves, only the underlying edge is split - so for example, if a CC is made up of 3 edges and the middle edge is split, the result would be two curves over the split edge, not two composite curves spanning the entire original CC, if that makes sense. I can't think of any way around this.
Only thing I see - it seems to need the splitting entity to be on or intersect. I tried points within .5mm and not working for that.
No problem; just noticed the behavior was different. Works fine - Considering you can use planes, faces, and 3Dpoint FS to get exact locations.
