Allows the averaging of points with duplicate identifiers. The process optionally allows averaging for XY position and/or elevation. A new point is created at the average XY position and/or average elevation according to the options selected.
Note that duplicate points with the same identifier can only be created if the Configure/Point Identifiers dialog box is set for non unique identifiers. This command is only active if the data base is set for non unique identifiers.
A number of flags are held against each point to indicate its status and to allow the resolving of duplicates. An understanding of these flags is of great benefit when using the Resolve Duplicates command. Please refer to the Point Status topic.
The Maintenance/Resolve Duplicates command is selected from the Plan View Utilities task.
Resolve Duplicate point Identifiers dialog box
Item | Used to |
Resolve Horizontal Position | Nominate that the average XY position of the selected duplicate points will be the XY position of the Resolved Point. |
Horizontal Tolerance (+/-) | Enter the XY search tolerance. Any duplicate points found within the search tolerance will be used in determining the average XY position of the Resolved point. Duplicate points outside the search tolerance will be ignored. The search tolerance area is a square with sides equal to twice the search tolerance, and with the current Main Point as centre. This field is not available unless the Resolve Horizontal Position check box is active. If this field is active and left blank, all points with the same identifier will be used. |
Resolve Vertical Position | Nominate that the average elevation of the selected duplicate points will be the elevation
of the Resolved Point. Note that duplicates cannot be resolved for elevation only, unless a Resolved point already exists |
Vertical Tolerance (+/-) | Enter the vertical search tolerance Any duplicate points found within the vertical search tolerance will be used in determining the average elevation of the Resolved point. Duplicate points outside the vertical search tolerance will be ignored. The extent of the vertical search is the current Main Point elevation plus or minus the vertical tolerance. This field is not available unless the Resolve Vertical Position check box is active. If this field is active and left blank, all points with the same identifier will be used. |
Delete Duplicates | Nominate that the duplicate points used in computing the position of the Resolved point are
to be deleted. Note that they will only be deleted if all occurrences of the duplicates were found within the search criteria. That is, if a duplicate exists outside the block definition, or outside the search area, or on a group which is not displayed, then the duplicates used will not be deleted. This is to ensure that all duplicates are used in determining the Resolved point before they can be automatically deleted. If duplicates are deleted, any lines attached are relocated to the resolved point. |
Point(s): | Enter the point identifiers to be resolved. Key in a single point identifier or snap to an existing point to have its identifier entered. Alternatively enter two point identifiers separated by two dots to specify a range. If the system is in Block mode, leaving this field blank will select all duplicate points within the block definition; entering a range will select those points which are both within the range and defined by the block. Note that a point will not be used if its group is not displayed. |
Apply | Carry out the resolve process and clear the Point(s) field. The Resolved point(s) is (are) created according to the selections made. If a Resolved point already existed it is moved according to the new average position and/or elevation computed. |
