Select a vertex

Nov 11, 2013 at 7:56 AM
I have imported a .stl geometry into Helix and I wonder if it is possible to select a point, a vertex or a surface in order to obtain the coordinates of that element. Thank you very much.

Try vanilla VisualTreeHelper.HitTest

or the Viewport3DHelper.FindHits extension method in this library.
