You can edit the values
and other properties of all attributes that are already attached
to a block and inserted in a drawing.
modify attributes in block definitions with the Block Attribute
Manager. For example, you can modify the following:
- Properties that define how values are
assigned to an attribute and whether or not the assigned value is
visible in the drawing area
- Properties that define how attribute
text is displayed in the drawing
- Properties that define the layer that
the attribute is on and the attribute line's color, weight, and
By default, attribute changes you make are applied
to all existing block references in the current drawing.
the attribute properties of existing block references does not affect the
values assigned to those blocks. For example, in a block containing
an attribute whose tag is Cost and value is 19.99, the 19.99 value
is unaffected if you change the tag from Cost to Unit Cost.
attributes with duplicate tag names can lead to unpredictable results.
Use the Block Attribute Manager to find duplicate tags and change tag
If constant attributes or nested attributed
blocks are affected by your changes, use REGEN to update the
display of those blocks in the drawing area.
Change the Prompt Order
for Attribute Values
When you define a block, the order in which
you select the attributes determines the order in which you are
prompted for attribute information when you insert the block. You
can use the Block Attribute Manager to change the order of prompts
that request attribute values.
Remove Block Attributes
can remove attributes from block definitions and from all existing
block references in the current drawing. Attributes removed from
existing block references do not disappear in the drawing area until
you regenerate the drawing using REGEN.
You cannot remove all attributes from a block;
at least one attribute must remain. If you need to remove all attributes,
redefine the block.
Update Block References
can update attributes in all block references in the current drawing
with changes you made to the block definition. For example, you
may have used the Block Attribute Manager to modify attribute properties
in several block definitions in your drawing but elected not to
automatically update existing block references when you made the
changes. Now that you are satisfied with the attribute changes you
made, you can apply those changes to all blocks in the current drawing.
You can also use ATTSYNC to update attribute
properties in block references to match their block definition,
or to update a block instance after you redefine a block attribute
using BLOCK, -BLOCK, or BEDIT.
Updating attribute properties in block references
does not affect any values that have been assigned to those attributes.
Edit Attributes in a Block
You can select an attribute in a block reference
and use the Properties palette to change its properties, or you
can use the Enhanced Attribute Editor to modify all the attributes
in a selected block reference.
To edit attributes assigned
to a block definition
To specify whether changes
are applied to existing block references
To highlight duplicate
attribute tags in a block
To change the prompt order
for attribute values
To remove an attribute
from a block definition and all block references
To update existing block
references with attributes you have modified
To update the attributes
in block references for a selected block definition
