None failed boolean operation

Can anybody solve this problem from detector construction?

I am creating simple union solids with the command line

G4UnionSolid * Union1_solid = new G4UnionSolid( "Union1", cyl_solid, Trap_solid, &TrapezRot, TrapezTrafo);

and a simple subtraction solid with

G4SubtractionSolid * cut_solid = new G4SubtractionSolid( "Schnitt", Union1_solid, Cutcyl_solid, 0, CutZylTrafo);

When using OpenGL or DAWN to visualize the detector I get

BooleanProcessor::triangulateContour : could not generate a triangle (infinite loop)

and the boolean operation fails.

Suggestions? Thanks! Patrick Achenbach
