Example use case:

http://help.solidworks.com/2011/English/api/sldworksapi/SolidWorks.Interop.sldworks~SolidWorks.Interop.sldworks.IModelDoc2~MaterialPropertyValues.html

MaterialPropertyValues Property (IModelDoc2)
C++/CLI	 
property Object^ MaterialPropertyValues {
   Object^ get();
   void set (Object^ value);
}

Wrapping the object in the correct type: http://www.ruby-doc.org/stdlib-1.9.3/libdoc/win32ole/rdoc/WIN32OLE_VARIANT.html http://www.ruby-doc.org/stdlib-2.0/libdoc/win32ole/rdoc/WIN32OLE/VARIANT.html http://www.pocketsoap.com/4s4c/docs/datatypes.html

Getter works

vals = model.MaterialPropertyValues

Naive setter does not behave as expected

model.MaterialPropertyValues = vals # sets to some erroneous values

See method info

h = model.ole_method_help('MaterialPropertyValues=')
puts h.name
puts " dispid:"
puts "   #{h.dispid}"
puts " args:"
h.params.each do |p|
  puts "   #{p.ole_type} #{p.name}"
end

Use an array of doubles

arr = WIN32OLE_VARIANT.array([vals.count], WIN32OLE::VARIANT::VT_R8)
(0..vals.count-1).to_a.each do |i|
   arr[i] = vals[i]
end
model.MaterialPropertyValues = arr
