Description
Importing mechanical models constructed in CAD to Geant4 has always been a challenge requiring a great effort on behalf of the physicist. Since no open-source and generic solution existed to bypass this problem, a new tool, GUIMesh, was developed with Python to convert STEP geometries into GDML as tessellated solids using FreeCAD libraries.
The tool allows to determine the precision of the tessellation and to assign materials to each volume in a matter of minutes. Validation of the imported geometries and materials and the impact of geometry precision on the computing speed as well as future prospects will be discussed.
