Yes, but not by Snapping, unless it's exactly at 1/2, 2/3, etc. when you can use "Snap Middle Point" and choose the total number of middle points. (Say, 1 point at 1/2, or two points(1/3, 2/3), etc.).

In other cases, you can trim a curve by the length to the original end points. The tool is by Menu:

Tools > Modify > Lengthen

Then, you can input the length from the end point to the desired point. negative/positive mean trimming/lengthening

If you want the original curve, you can make a copy before running Length.

I need to place points along a curve, whose location is not defined by x,y or in a straight-line distance from the previous point, but distance along an irregular curve. Is this possible? Thanks.
