Retrieve the coordinate of mouse

[youssefGC]

Hi everyone,
I have a question: is it possible to retrieve the coordinate of position of the mouse cursor at the moment the user picks an entity using "PromptEntityOptions"? In other words, can I obtain the coordinates of the point where the user makes the selection?

Thank you.

The  PromptEntityResult Class has a    PromptEntityResult.PickedPoint Property

Perhaps try that.

The description says 'Gets the point that was used to pick the entity.'

. . but I don't recall exactly if that is the center of the pickbox or the nearest point on the entity, you'd need to check before relying on it to be sure.

I think it is the pickbox center, so you may need something like

Curve.GetClosestPointTo([PickedPoint], false)

PromptEntityResult.PickedPoint, which is where the mouse location when clicked and may not be right on the curve (in your case). If you need to know the exact point on the curve, you need to calculate it with:

Curve.GetClosestPointTo([PickedPoint], false) to obtain the exact point on the curve.
