Example:
|
|
Registered for this drawing are blocks #1 and #3 (shape identifiers
|
|
1025-2048 and 3073-4096).
|
|
Shape identifier 1025 -> local shape index 1.

|
Shape identifier 1026 -> local shape index 2.
|
|
...
|
|
Shape identifier 2048 -> local shape index 1024.
|
|
Shape identifier 3073 -> local shape index 1025.
|
|
...
|
|
Shape identifier 4096 -> local shape index 2048.
