ComponentPartParameter
One editable parameter of one part of a component definition, as a formula inside that component reads it: `part.parameter` (construct-component-parity §CPF-A3.2, `rim.majorDiameter`).
In the namespace construct::ui. Declared in src/libs/libconstruct/construct/ui/EditorScope.hpp.
Detailed description
EditorScope::componentPartParameters() lists them. The component dialog's Add menu offers them and EditorScope::forComponent() completes them, from that one list, so the menu never offers a name the formula editor would refuse (construct-field-defects §CFD-D-11).
