Task: Contact and Cross-Reference Update across Multiple Drawings
The task is to 1) tie a relay contact in to a relay coil when the coil is on some other drawing in your overall drawing set, and 2)
show the appropriate bi-directional cross-reference annotation, child pointing at the parent coil and the parent coil pointing
at the child contact(s), listing them in a tabular format.
Steps
1. Open the second drawing of a multi-drawing project and insert
several relay contact symbols.
2. Tie each to a parent coil symbol on the first drawing in the
project set.
3. Update cross-reference information on both the contact and on
the parent coil symbol.
Study Results
In basic AutoCAD, you are again “on you own” for both 1) finding the
tag-ID of the parent relay coil that might be anywhere
in your project set, 2) figuring out the next available set of contact
pin number assignments, and then 3) updating the
cross-reference annotation at both ends. This can be frustrating
when you don’t know what drawing the relay coil might
be on. In AutoCAD more than 6 times as many commands were used and accessed to complete this task versus with
AutoCAD Electrical.
Advantages of AutoCAD Electrical
• Tracks contact usage across dozens or hundreds of drawings in your project so you don’t have to.
• Simple selection from real-time list of parent relays. Error checking, auto-pin list assignment, auto-tagging.
• Bi-directional cross-referencing updates automatically, even when a complex tabular cross-referencing
format is selected.

Time Saving with AutoCAD Electrical — 95%
Reduce the risk of assigning too many contacts to any relay, and minimize time
spent manually tracking assignments. AutoCAD Electrical sets up parent/child
relationships between coils and contacts, keeping track of how many contacts
are assigned to any coil or multicontact device, and alerting users when they
have exceeded the limit.
