[ d ] Drawing Execution Processing Method
The execution processing of hierarchical drawings are performed by calling lower-level drawings from higher-level
drawings.
The following figure shows the execution processing for drawings, using DWG.A as an example.
Note: 1. Parent drawing is automatically called and executed by system. Therefore, you can execute the child
and grandchild drawings by programming a DWG reference command (SEE command) in the parent
and child drawings.
2. Functions can be referenced from any drawing. Functions can also be referenced from other functions.
3. When an operation error occurs, the operation error processing drawing for that drawing will be
started.
