Define curve.startpoint

[alvis.narmonts]

Hi!
Is there a way to define the Curve.StartPoint location on a curve, so that it is not the actual start of the curve, but, for instance, 500 mm from the start?
What I’m attempting to do is to create a spiraling reinforcement inside a rectangular column (driven pile). The idea is to create points along the vertical reinforcing bars, draw a polyline trough those points and then place rebar on this line.

This is how the script looks like at the moment.

Hi Alvis,

Try curve point at segment length or point at parameter, and give suitable inputs (-ve aswell).

I went an alternative way (at least it could be) where I used the Curve.TrimByStartParameter and calculated the value that needs to be cut from the start. Looks like it works. Will check your suggestion a little later. Thanks.
