Clean Lines (CleLin)
Type: Batch Application
Searches for duplicate points on lines.
Detailed Description
Clean Lines searches for duplicate points on lines within user specified layers. The search parameter include separate xy and z search tolerances. This allows the searching of points that may have the same xy coordinates but different elevations. Duplicate point actions include the ability to delete the first or last occurrence of the duplicate points or to place the duplicate point positions into a Drive File. If the points are placed in a drive file then the duplicate points are not deleted.
Options include the ability to search for duplicate sequential and(or) non-sequential duplicate points on lines. The ability to place all duplicate points or one duplicate per line is available also.
Whenever a line is saved into the VrOne database duplicate points in which the XY and Z coordinates are the same are removed. Clean Lines differs in the it searches for line points with duplicate XY coordinates but different elevations. Also, the XY and Z tolerances that define a duplicate point are user defined.
Parameters for Clean Lines
The Clean Lines dialog
Workspaces to consider
Defines the workspaces to consider when running Clean Lines. Options are Current workspace or All open workspaces.
Layers to search (NumLine)
Defines the layers to search for lines with duplicate points. A Number Line may be used to specify multiple layers.
Delete Action
Defines the action to take on duplicate points. The options for Delete Action include the following.
| • | Delete first - Deletes the first occurrence of the duplicate point |
| • | Delete last - Deletes the last occurrence of the duplicate points |
| • | Add to drive file - Places the duplicate point position in a drive file and does not modify the line. |
Delete sequential duplicate points
If checked then points that are within the xy tolerance and are sequential will be considered as duplicates.
Delete non-sequential duplicate points
If checked then points that are within the xy tolerance and are not sequential will be considered as duplicates. Duplicate points a the beginning and end of a line that close the line will not be considered duplicate.
Drive file mode
This parameter determined what duplicate points are placed in the drive file when the Delete Action is set to "Add to drive file". The options include the following.
| • | All duplicate points - All duplicate points are placed in the drive file. |
| • | One duplicate point per line - Only the first duplicate point found on a line will be placed in the drive file. This is useful when lines have many duplicates. |
XY Tolerance
Line points must be within this distance in the XY direction to be considered duplicate. The Z tolerance is considered also. This parameter is entered as ground units.
Z Tolerance
Line points must be within this distance in the Z direction to be considered duplicate. The XY tolerance is considered also. This parameter is entered as ground units.
NOTE:
Lines that turn back on themselves may product undesired results. Files should be backed up before running Clean Lines and the results should be checked.
