Cartographic Representation Work Flow

If you please, I'd be interested in understanding the best work flow to get from "Reality" to "Clarity" as indicated in the attached image.

The left map shows transmission features with a high degree of spatial accuracy. Only useful for mapping at the largest scales.

The right shows a copy of the features (modified data - no reps) for use in small scale mapping.

How can I get from one to the other with Cartographic Representations?

The goal for the cartographic version is precision with standard offsets and ordinate vector directions as much as possible.

Seems this would involve considerable manual editing of the Representations and use of snapping environments.

Then a completely new effort to create different Representations for each scale range, large to small.

Any clarification - a cognitive representation, so to speak, would be appreciated!

Mapping Center Answer:

What you're describing is a text book example of schematic and route mapping, where multiple topologically coincident line features need to be exploded somehow for clearer visualization. You are correct in your observation that this is a labor-intensive task when editing representations, but it can be done. However, a more automated solution is available by using ArcSchematics, which contains functionality designed to do exactly this type of map. I refer you to a Mapping Center blog which we wrote on this topic for more information.

...the prompt and informative reply!

ArcSchematics is something I considered for cartographic purposes way back when it was first released. Guess I'll revisit it.
