Convert DgnModelRefP to DgnModelCR

I think the activeModelCR is incorrectly defined

This article discusses the typedefs in the MicroStationAPI. 

DgnModelCR is an alias of typedef of DgnModel generated by a macro in DgnPlatform.h.  Once you dispense with the noise, you will see something like this:

typedef DgnModel& DgnModelR;
typedef DgnModel const& DgnModelCR;

NamedBoundaryCollection::Create takes a DgnModel by const reference.  What that tells you is the the function will not attempt to modify the DgnModel.

I'm not sure the casting is done correctly

You're declaring a variable of type const reference to the type you receive from a function. If the compiler is satisified then look to  NamedBoundaryCollection::Create().  Unfortunately there is no example for named boundaries.

I seem to have confused Named Boundary with Drawing Boundary. The following code actually runs as expected:

// find named boundaries
DgnModelRefP activeModelRefP = mdlModelRef_getActive();
DgnModelCR activeModelCR = *activeModelRefP->GetDgnModelP();

NamedBoundaryCollectionPtr collection = NamedBoundaryCollection::Create(activeModelCR);
boundaryCount = collection->GetCount();

for (NamedBoundaryCollection::const_iterator iter = collection->begin(); iter != collection->end(); ++iter)
{
	WString name = (*iter)->GetName();
	ElementHandle elemHandle = (*iter)->GetGraphicalElement();
	MSElementCP elemCP = elemHandle.GetElementCP();
}

I was trying to access the Drawing Boundaries contained in a sheet model which requires different coding.

Thanks for helping me figure that out.
