GetPointOnCurve extend cursor distance

[onrender]

Hello,

Prevoiously I had a question how to add points that is located on a line however I realised when I drag the cursor far away from the line the selection does not function. The cursor needs to be very close to the line to apply the point. Is there any way to increase the cursor distance from the line?

Select point on a vector

Hi, I cannot find the way how to select a point on a given vector or a line. I would like to select and visualize the point on a line. Should I use projection. Is there a method for this? (I already find how to visualize it by dynamic display) Thanks,

Hi @onrender,

Try replacing this:

gp.Constrain(Rhino.Geometry.Line(ptA,ptB))

with this:

gp.Constrain(Rhino.Geometry.LineCurve(ptA,ptB), False) 

Any better?

Thank you Dale,

Actually, I tried with Python code but the C# code works like as I expected, so the point follows the cursor regardless of its position on the screen.
