Max.NET: Convert to TriObject

Hey, I am trying to convert a GeomObject to a TriObject in Max.Net. I am using this code: if (os.Obj.CanConvertToType(global.TriObjectClassID) != 0) { ITriObject triObjConv = (ITriObject)(os.Obj.ConvertToType(0, global.TriObjectClassID)); } At runtime Max.Net throws an exception: "Object of type Autodesk.Max.Wrappers.GeomObject" can not be converted to type "Autodesk.Max.ITriObject". The reason is that the ConvertToType method return an object of type "GeomObject" - but actually the method is asked to deliver an ITriObject as the classID is given as argument. Is there a mistake in Max.Net or must it been done in a different way? Thx ind advance Greets, Michbeck

EPHERE	Hi Mitchbeck, I think this is the same issue as http://ephere.com/autodesk/max/forums/general/thread_960.html Marsel Khadiyev (Software Developer, EPHERE Inc.)

MichiMichbeck	Yes I guess this is the same issue, but there was no solution found in this thread either, was it? I tried to set the ClassID given in this thread but it didnt work. Actually I tried the following: ITriObject triObj = this.global.CreateNewTriObject; IClass_ID objID = triObj.ClassID; IClass_ID triObjID = global.TriObjectClassID; Both ClassID's (tribObjID and objID) are different: objID = ( 3830386867 , 0 ) , triObjID = ( 9 , 0 ). So ClassID's for different triObject should always be equal, right? Is that somehow the root of the problem? Thx,Regards Michbeck

EPHERE	The solution doesn't exist in current build, however, I already fixed it and it should be working in next build. The reason is that returned objects are of editable mesh or editable poly types (rather than triobject or polyobject). Marsel Khadiyev (Software Developer, EPHERE Inc.)
