Nested Blocks
The line BL:LEVEL in a template file reports the nesting level of a block
reference. A block that is inserted in a drawing has a nesting level of 1. A block
reference that is part of (nested within) another block has a nesting level of
2, and so on.
For a nested block reference, the X,Y, Z coordinate values, scale factors,
extrusion direction, and rotation angle reflect the actual location, size,
orientation, and rotation of the nested block in the world coordinate system.
In some complex cases, nested block references cannot be correctly represented
with only two scale factors and a rotation angle, for example, if a nested block
reference is rotated in 3D. When this happens, the scale factors and rotation
angle in the extracted file record are set to zero.
Error Handling
If a field is not wide enough for the data that is to be placed in it, the data is
truncated and the following message is displayed:
** Field overflow in record <record number>
This could happen, for example, if you have a BL:NAME field with a width of
8 characters and a block in your drawing has a name 10 characters long.
Quick Reference
ATTEXT
Extracts attribute data, informational text associated with a block, into a file.
Modify Blocks
You can modify a block definition or a block reference already inserted in the
drawing.
Modify a Block Definition
You can redefine block definitions in your current drawing. Redefining a block
definition affects both previous and future insertions of the block in the current
drawing and any associated attributes.
