When a drawing is compared using DWG Compare, what visual aid highlights changes?

1. Markers on the drawing

2. A revision cloud

3. Color coding

4. Text comments

The correct answer is: A revision cloud

In the context of using DWG Compare within AutoCAD, the correct visual aid that highlights changes is a revision cloud. This tool is specifically designed to visually indicate areas in a drawing that have been modified or changed when comparing two versions of the same file. The revision cloud creates an irregular, cloud-like graphic outline around the differing features, making it easy for users to quickly identify modifications between the compared drawings. The revision cloud serves an important function during design reviews and revisions, as it visually separates newly added or altered elements from unchanged parts of the drawing. This clarity helps in understanding the specific areas that require further review or attention. Color coding can also be useful in highlighting changes, but it typically applies to the different types of changes rather than pinpointing specific areas in a drawing like a revision cloud does. Markers and text comments can provide additional context and information regarding changes, but they do not serve as a direct visual representation of the altered areas in the same way a revision cloud does.
