Working with ISurface.Locate method

Discussion created by alcaraz on Dec 13, 2011
Hi, I need to work with ISurface.Locate method, but the help topic of arcobjects is not enough detailed.

Function Locate( ByVal pRay As IRay, ByVal hint As Long ) As IPoint

I don't understand what hint is.

Otherwise, if I use a ITinSurface, the method returns points in the middle of the tin triangles, is that correct for this method?

Thanks a lot, Mar
