Question Problem with G4UnionSolid 

Forum: Geometry
Date: 28 Feb, 2017
From: Emanuele Leonardi <Emanuele Leonardi>

I am trying to create a structure which is a succession of adjacent boxes and trapezoids.

If I generate the single parts independently and position them directly in my world volume, everything looks fine.

If I try to create a single volume by creating the first part of the structure and then attaching the other parts with repeated calls to G4UnionSolid, the final solid generates repeated errors in the visualization phase (I tried both OGL and HepRep):

BooleanProcessor: corrapted input polyhedron
BooleanProcessor::createPolyhedron : too many edges

and the structure is not shown correctly: some of the parts are completely missing while others are shown with missing edges.

Is there a problem with G4UnionSolid or I am using it in the wrong way?
