One of the main problems LHCb users have been facing when using DD4hep is the concept of Handles and its oddities compared to 'standard' C++ objects. Just to cite a few :
- passing handles as refe…

Certain Run 1 scenarios have Polycone definitions in their XML files with duplicate planes. These definitions in the XML files need to be changed so the z/rMin/rMax sections are unique. This problem a…

As discussed in PR #1, we need a way to allow for changes to detector alignment from the "ideal" design parameters. At present, the only apparent way to modify the geometry is via hardcoded changes in…

Currently JANA2 installs plugins into the `/plugins` directory. This directory that could resolve (for system-wide installs) to e.g. `/usr/plugins` which is non-standard and can lead to conflicts when…

Hepmc3 vertices contain a status code which there currently appears no way to keep to the DD4hep output (edm4hep).
We are wanting to use hepmc events which will contain several vertices coming from…
