Question Boolean geometry scale factor  

Forum: Geometry
Date: 01 Nov, 2016
From: Maura E.M. <Maura E.M.>

I have created a composite MultiLeaf Collimator out of 3 Geant4 boxes, 1 GenericTrap, and 2 Tubs using boolean operations. The measurements driving the construction of the composite MLC were otained by similarity of triangles in the global coordinate system of a Linac model that includes the MLC as a component. Usage of such measurements during the construction of the MLC cause a visible unaspected discrepancy in the displayed geometry. It looks like there is scaling factor affecting the results. I am aware that translations and rotations applied to boolean components take place in the coordinate system of the "host" component. I wonder if there is a way to evaluate the scaling factor between the local coordinate system of the boolen component and the global coordinate system where such a component is actually included. Thank you in advance.
