Pick a point

[fabrice]

How to let user pick a point ?

Do anyone know?

Thanks!

there are no points in revit.

I know that!!!!

I want to let the user draw something and let him/her use the snap tool, and thus, pick points.

there are no points in revit.
And what layer are those points not on?:beer:...

The closest thing to picking a point in regular Revit is placing a Spot Dimension. I'd think that would have some useful properties. Would that be accessible though API?

Although it's not clear exactly what you're trying to do I think either you

a.. Use the pickone() method to select and element and extract points from the selected element

b.. Use win32 API's to try and get the point information you require from the screen.

HTH,

Thanks Guy, that's about want I want to do. But I guess from your answer, the snap won't work. Too bad.

Snap is essentially a User interaction device. Therefore I'm guessing it would technically be possible to implement something similar via the API.

eg (Pseudo code)

Get wall start point and end point.
Is wall modulo 4inches(snap distance)?
If yes draw wall, if not ask for new selection.
