Undocumented Commands to Resolve Site Specific Issues

There are four undocumented commands to help you resolve Site specific issues. The use of these commands requires the use of AutoCAD Civil 3D 2009 Update 2.1.

Before using these commands, be sure to AUDIT your drawings and check for the existence of an abnormal number of Registered Applications.

AeccFindSiteOverlaps

Start with this command, which will check for overlapping alignments, feature lines, and lot lines in a Site. A dialog box will be displayed, prompting you to select the Site to check. This command will mark any overlapping locations found with AutoCAD points, placed on the layer _OVERLAPPING_SEGMENT_LOCATIONS.

Note: To see the AutoCAD points better, you can use the DDPTYPE command to change the visibility settings if necessary, which will force a Regen. However, in cases with unstable Gradings or behavior a Regen may result in a crash.

Press the F2 button to review the command line. You will see the result of the check, and it will tell you which of the following commands to use to remove the overlaps.

Once you have performed the first set of recommended corrections, erase the AutoCAD points that were created and then run the AeccFindSiteOverlaps command again to see if any overlaps remain.

AeccRemoveDupFeatureLines

This command will move each overlapping feature line to its own individual Site, with the name “Overlap X” (Overlap 1, Overlap 2, and so on.). This command will not remove feature lines that use grading criteria. The thought here is that feature lines used simply as breaklines will be removed to separate sites but can still be used to create surfaces. Feature lines created from Survey data will only be included if they are part of a named Site.

AeccRemoveAlignmentsFromSite

This command moves alignments to the Alignments collection in Prospector. The alignments will no longer be part of the Site, but their names will be maintained.

AeccRemoveDupLotLines

This command performs the same function as AeccRemoveDupFeatureLines command above, except it will move overlapping parcel lot lines to separate Sites. It operates on the linework, not the parcels themselves, so removing some of the parcel linework to its own site may either create new parcels or remove existing parcels (a similar effect to moving the lines with the Move to Site command).

Additional tip: If, after removing any overlaps that can be found, there are overlaps reported for gradings, it may be possible to edit the gradings slightly so that they no longer overlap. For example, one case that may cause problems is when two grading footprints touch each other at a point where the grading projection lines overlap. In this case, the appropriate fix would be to remove the gradings and join the footprint. Use a single transition at that point instead of having two adjacent gradings.
