While you work, you can manipulate the geometry in a dynamic block reference through custom grips or custom properties instead of searching for another block to insert, or redefining the existing one.

For example, the size of a door block reference in a drawing might need to change while you're editing the drawing. If the block is dynamic and defined to have an adjustable size, you can drag the custom grip or by specify a different size in the Properties palette. The door block might also contain an alignment grip, which allows you to align the door block reference easily to other geometry in the drawing.

You can create a block from scratch, or you can add dynamic behavior to an existing block definition. You can also create geometry, just as you would in the drawing area.

Parameters and actions are displayed only in the Block Editor. When you insert a dynamic block reference in a drawing, the parameters and actions contained in the dynamic block definition are not displayed.
