A Block is a collection of entities bound together as a single entity. After you create a Block, you can insert it whenever you need it in a drawing.
When you use the MakeBlock command, the Block is recognized in the current drawing only. The ExportDrawing command lets you write a Block to an external drawing file for use in any drawing.
To define Blocks:
- Click Draw > Block > Define (or type MakeBlock).
