Hi Vladimir,

I've talked with Harald a little bit about this offline, but I've been too busy with the upcoming SLAC Tutorial to follow up, so it would be great if you could have a look.

Here's what I've understood from Harald:

The question is with the Polyhedra solid.

The Application Developers Guide calls:

rInner Tangent distance to inner surface

rOuter Tangent distance to outer surface

The question is whether these tangents are the distance to the middle of a face or to an edge. The text mentioned above says distance to a face, but the figure seems to show this as the distance to an edge.

Harald measured the distance using HepRApp and it seems to be distance to a face.

Can you clarify which is correct?
