There are several regions in Geant4 baseline geometry where new volumes of services and supports should be added. Also several existing volumes should be replaced due to detector upgrades. Purpose of the WP is to build so called “Loop” between design engineers and simulation team. Design geometry will be extracted from the engineering database and reproduced into CATIA by adding missing drawings. Than 3D model will be simplified with keeping source volume and weight, transfer into XML and send to Muon simulation team for final upgrade of Geant4 baseline geometry. Georgian Team will use unique simulation loop on CATIA platform developed together with ATLAS simulation team.
