Interesting... it looks to me like the XSICollection is changing the object type as a result of dumping it into the collection:
SelectObj("cube", null, true);
obj = Selection(0);
// Get a pointer to the object Facets
oFacets = obj.ActivePrimitive.Geometry.Facets;
LogMessage(oFacets(0))
LogMessage(oFacets(1).type)
// Dump the objects into an XSICollection
XSIColl = new ActiveXObject('XSI.Collection')
XSIColl.AddItems(oFacets)
LogMessage(XSIColl(0))
LogMessage(XSIColl(1).type)
This looks like a job for Andrew!

Stephen,
Thanks, this worked perfecly for my oFilter.Subset input, however I am
now more confused than ever. I have two pieces of code that are supposed
to select all the edges of a particular facet, one works, one doesnt,
they are:
//1.DOES NOT WORK
SelectObj("cube", null, true);
var oColl = XSIFactory.CreateActiveXObject("XSI.Collection")
oColl.AddItems(Selection(0).ActivePrimitive.Geometry.Facets);
SelectGeometryComponents(oColl(0).Edges);
//2.WORKS
SelectObj("cube", null, true);
var oSelList = Selection(0).ActivePrimitive.Geometry.Facets;
SelectGeometryComponents(oSelList(1).Edges);
If Selection(0).ActivePrimitive.Geometry.Facets is a facet collection,
how does it differ from an XSI Collection? In this case it would seem
that the XSI Collection is being passed to SelectGeometryComponents in
example 1 and a Facet Collection is being sent to
SelectGeometryComponents in example 2. Why would the XSI Collection work
in the case of filter.subset but not here?
