This report examines the distinct element-layout schemes inherited from OPAL-T and OPAL-CYCL before proposing how OPALX could make the relevant layout capabilities available consistently. It covers relative and global placement, coordinate transforms, beamline containers, and the roles of OpalElement, Element, and ElementBase.

The document is retained as an experimental design record, not as a description of a finalized user interface. Verify implementation details against the current source before relying on the proposed class or attribute changes.
