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?
