BLOCK
Modify Block Attributes
You can 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 type
By default, attribute changes you make are applied to all existing block
references in the current drawing.
Changing 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.
Updating attributes with duplicate tag names can lead to unpredictable
results. Use the Block Attribute Manager to find duplicate tags and change
tag names.
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 deter-
mines 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.
