# Use the specified interface; useful for sharing attributes with other

# @example

# # use the width of another interface
# width Vedeu.use('my_other_interface').width
# # ...

# Vedeu.use('my_other_interface').width # can be used in your code to
# # get this value

# @param value [String] The name of the interface you wish to use.
# Typically used when defining interfaces to share geometry.
# @raise [ModelNotFound] The interface has not yet been defined.
