get translated world coordinates on Z plane

[MarkusR]

Hi,

is there a way to get translated coordinates from a Z plane?
if there would be an object I could use SoRayPickAction, however I want to get the world coordinates outside of the object on a defined Z plane,
or do I have to create a temporary plane for selection in that case?
In case of a temporary plane - could there be an invisible plane?

I'm currently looking at SbProjector / SbPlaneProjector it seems to be useful for that task

OpenInventor is new to me

Update, I just figured it out, and yes it seems like I was on the right path with it.

thanks
