Description
The GDML Workbench (https://github.com/KeithSloan/GDML) is an optional workbench available for the open source project FreeCAD (https://www.freecad.org). Geometry created within FreeCAD can be exported as a GDML file (for reading by Geant4); the workbench also can also import GDML files for viewing/editing. All the GDML geometry primitives are supported, plus several useful FreeCAD constructs, such as arrays (rectilinear, polar, along a path or arbitrary points), extruded and revolved 2D sketches. Optical surfaces are also supported. Materials for each volume can be created or chosen from the included list of NIST materials. The status of the workbench and example uses will be presented.
