Creating derived drawings using Internal Reference (Enlarged drawings, detailed drawings, etc.)

An Internal Reference is a function for effectively creating derived drawings such as detailed drawings and plan drawings. If some or all of the drawings are designated as internal references, they are in block form. Therefore, it refer to a function that supports creation of drawings by linking information with a shape object.


All drawings created by internal reference are connected.


When the original drawing is modified, the linked drawings are collectively modified.
