All of the errors on the map are violations of the Must Not Have Dangles rule. However, there are several different problems that can cause this type of error. A dangle error can be caused by a line that extends too far beyond the line it is supposed to touch or by a line that doesn’t extend quite far enough. These are called overshoots and undershoots, respectively.

Dangles can also occur where features have been digitized from adjacent map sheets. These lines sometimes need to be snapped together so they connect to form a continuous line. Other dangle errors occur at the edge of map sheets, where a line is cut off on the original source data.

Click 3930 in the Feature 1 column. The feature flashes on the map, and the error feature turns black to show that it’s selected. Zoom in to the feature until you can see where the lot line with the error crosses the other lot line.

This is an overshoot error, a type of error that is often found in line work imported from CAD programs or digitized without using snapping to control the connectivity of the line features.

You can trim a feature by right-clicking the error in the Error Inspector and clicking Trim. The Trim error fix lets you specify a Maximum Distance. Dangles longer than this length will not be trimmed.

The Error Inspector context menu provided a list of potential fixes for this error. You trimmed the line feature to fix this error. You also could have marked the error as an exception or snapped or extended the line until it reached another feature.
