Dynamic block references contain grips or custom properties that change the way the reference is displayed in the drawing after it is inserted. For example, a dynamic block reference of a door can change size after you insert the block reference into your drawing. Dynamic blocks allow you to insert one block that can change shape, size, or configuration, instead of inserting one of many static block definitions.
Dynamic blocks that contain action parameters display grips that are associated with a point, object, or region in the block definition. When you edit the grip, an associated action is triggered that changes the way the block reference is displayed.
You can hover over a grip to display a tooltip or prompt that explains the parameter related to the grip. The display of the tooltip is controlled by theGRIPTIPS system variable.
Some dynamic blocks are defined so that geometry within the block can only be edited to certain sizes specified in the block definition. When you use a grip to edit the block reference, tick marks are displayed at the locations of valid values for the block reference. If you change a block property value to a value other than one specified in the definition, the parameter will adjust to the closest valid value.
