This dialog allows you create a new instrument block type or modify properties of
one or more existing instrument types you selected in the Drawing Block Types folder of the Domain Explorer. Instrument block types are shown with the icon 
. A block type that you add becomes available in all the <plants> of the current domain
because block types are defined at the domain level.
Block type
Allows you to type a unique name for the new instrument block type. Block type names are not case- sensitive. For example, block type names MyBlockType and myBlockType are considered not unique.
Block type description
Allows you to type an optional description for the new block type.
