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.
Modify Blocks
You can modify a block definition or a block reference already inserted in the
drawing.
Modify a Block Definition
When you redefine block definitions in your current drawing, both previous
and future insertions of the block in the drawing are affected.
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.
There are two methods for redefining a block definition:
Modify the block definition in the current drawing.
Modify the block definition in the source drawing and reinsert it into the
current drawing.
The method you choose depends on whether you want to make changes in
the current drawing only or in a source drawing also.
Modify a Block Definition in the Current Drawing
To modify a block definition, follow the procedure to create a new block
definition, but enter the name of the existing block definition. This replaces
