Read IFC object type properties like OverAllWidth and OverAllHeght of IfcDoor and IfcWindow


In version 1001.0.2 all Ifc object type properties that are primitive types are saved to
vdIFCProduct.PropertiesGroup("IFC_TYPE_PROPS") collection
The primitive types are Boolean, Byte, SByte, Int16, UInt16, Int32, UInt32, Int64, UInt64, IntPtr, UIntPtr, Char, Double, and Single.
NOTE: these properties are also exported to IFC object object types when saving as IFC format


//get the OverAllWidth property usually from a vdIFCProduct object with IFCType = IFCDOOR or IFC WIDNOW
vdIFCProduct obj;
vdIFCProperties ifcprops = obj.PropertiesGroup.FindName("IFC_TYPE_PROPS");
if(ifcprops == null) return;
object value = ifcprops.Properties["OverAllWidth"];
if(!(value is double)) return;
return (double)value;
