Editing Block Definitions

Use the Block Editor to edit Block definitions. To open the Block Editor, use the EditBlock command. Alternatively, double-click a Block reference in the graphics area.

You can do the following changes to the Block:

• Modify geometry using modification tools and commands. You can add, delete, and modify the Block entities.
• Modify properties of any entity in the graphics area by using the Properties palette.
• Add elements and activities to the Block definitions to create CustomBlocks.

You can add, delete, and modify these entities within a CustomBlock definition:

• Constraints
• Elements
• Activities
• Visibility states
• Value tables
• Grip points
• Custom properties

The Properties palette is available in the Block Editor. You can select and modify the properties of entities in the graphics area such as geometric entities, elements, and activities.

To finish the Block editing session, use the CBClose command and save the Block. See Saving CustomBlocks.

All instances of modified Blocks and References update in the drawing.
