Specifies the original block name.
The object or objects this property applies to.
The effective name is the name of the block as the user would see it in the user interface. Dynamic blocks may draw themselves with an anonymous block whose name is different than the block name the user sees for the block in the user interface. The Name property returns the name of the block used to draw the reference, while the EffectiveName is the name the user sees for the reference.
