Is there a reason CurrentLength is not available for a curve’s function? It would be nice to have that.

I don’t know, but here are my thoughts/intuitions:
-
When making a curve that would be a straight line, so why even use the curve tool?
-
When segmenting a curve the curve’s name shows in a drop-down in the dialog, (eg:Spl_A_A3) which is shorter to write than CurrentLength
. -
But I have assumed that the real reason has to do with why there’s a drop-down to choose which curve one wishes to segment, when one clearly already chose which curve to segment! (Of course, it comes in handy when I realize I got confused about which string of a knot I was clicking on.
)

- I don’t understand your first point. If you have a curve, it’s likely because a straight line is not going to get the job done.
- The selection of the curve can actually take a long time because of having to hunt through the dropdown list which can be very large in a complex pattern.
- It’s safer to use CurrentLength compared to selecting a curve, since then there is no risk of accidentally selecting the wrong curve from the dropdown.

Exactly. That was just my clumsy attempt at covering that one possible option before going on to more likely territories.

No, what I was trying to say was selecting it on the diagram, but then typing in its name is easy because it is what’s showing in the dropdown.

I think that probably the reason why one cannot use CurrentLength when segmenting curves is because of the same reason why they even have a generally not very useful, (to us,) drop-down. It probably has something to do with the way they are stored in the xml, but I haven’t been able to make enough sense of the xml to tell if that’s a reasonable hypothesis.
Hopefully @kmf, @slspencer, or someone else who has some level of understanding of the code can bring some real illumination to this question soon.

This is something that simply wasn’t implemented and needs to be developed.
