Abaqus - Shared parametric dimension between different parts in Abaqus/CAE

Hello, is it possible in Abaqus/CAE to create 2 parts which share a common dimension (as a parameter). This is needed for a DoE in which one dimension in one part must be linked to one in another part (example: pin and hole must keep the same diameter during the DoE)

On a separate but related subject: is there any plugin to handle analysis parameters from within Abaqus/CAE?
