Detailed Description

A type of cell for which graphics are generated parametrically.

Parametric Cells are similar to shared cells in that:

All cell instances refer to a single "cell definition" stored in the dictionary model
Cell instances are non-complex elements
Only one copy of the elements defining the cell geometry exists, no matter how many cell instances are created
When a cell instance is copied between DgnFiles, it is remapped to use an existing cell definition by the same name in the destination file; or otherwise the cell definition is copied to the destination file

Parametric Cells differ from shared cells in that:

The cell geometry is stored within a hidden DgnModel rather than a complex element
In addition to overriding the transform, cell instances can override the parameters which control the generated geometry
Only models of CellLibraryType::Parametric can be placed as parametric cells
Models of CellLibraryType::Parametric cannot be placed as shared or normal cells
