RE: [CONNECT MicroStationAPI] Where is the element type enum?

[quote user="Bruce Reeves SRNS"]They (e.g. CELL_LIB_ELM) don't appear to be in my "dgnplatform.r.h"[/quote]

You picked the one value (CELL_LIB_ELM) that is not defined any more.  Cell libs haven't been an element type since V8.0. I found the enum where Brien indicated (in the SDK for Update 2)...

#include <DgnPlatform/DgnPlatform.r.h>
enum MSElementTypes
{
    CELL_HEADER_ELM                 = 2,
    ...
    MSELEMENTTYPES_MaxElements      = 113
};
