1.The InRoads “method” of resolving crossing breaklines that result from conflicting elevations at the crossing location is to drop the status of the shorter breakline, and thereby eliminating the conflict. The user must evaluate this automatic modification and take the correct action to resolve the conflict. pg. 263
2. When surface data is very dense, triangulation can encounter tolerance problems. This may result from a number of things such as too low a chord height tolerance for imported graphics or template drops that are too tight. Two methods may resolve this problem: 1) If importing graphics, try increasing the Chord Height Tolerance under Settings> Preferences> Tolerance or use the “thin” option on the Import Graphics command. 2) Try using the Transform Surface command to translate the surface by some very small amount (such as 1e-6) in the northing and/or easting direction. This may help to work around the value that is causing the tolerance problem. pg. 263 |
