Least Squares Adjustment Editor: Edit Menu

(This functionality is available with the Adjustment module)

On selecting the Edit menu from the Least Squares Adjustment Editor, the following commands become available.

	Menu	Used to
	Insert	Insert a blank row in the editor: The new row is to be inserted before the selected row.
	Delete	Delete the selected row from the editor:
	Clear	Deletes the contents of the currently highlighted cell.
	Cut	Cut the selected row to the clipboard.
	Copy	Copy the selected row to the clipboard.
	Paste	Paste a row from the clipboard to the editor.
	Fix	Toggle whether a co-ordinate, angle, bearing or distance is to be held fixed (locked).
	Exclude Observation	Excludes an observation from the adjustment process. Select the entire row/s of the observation/s you wish to exclude, then either toggle the toolbar button or choose this option from the Edit Menu. This will cause the excluded row/s to be highlighted/hatched, therefore the user can easily see which measurements are to be used in the adjustment and which are to be excluded.
	Set Reference	Toggle whether a direction is a reference direction. A reference direction is underlined and is the start of a set of directions which were measured in relation to the reference direction.
	Set Bearing	Toggle whether a direction is orientated. That is, whether it is a direction or a bearing. A bearing is shown in italic.
	Retrieve Co-ordinates	Retrieve co-ordinates from the currently open database and place them in the Least Squares Adjustment Editor. First, select the required record and then select this command. If the co-ordinates of the AT point are present in the database, they are copied to the Least Squares Adjustment Editor as fixed co-ordinates. If you inadvertently have any fixed co-ordinates against points that are to be adjusted, swipe and delete them before trying to adjust. To select a record click on the appropriate number in the left-hand column of the spreadsheet. The entire row of the record will be highlighted.
	Modify Standard Deviations	Brings up the dialog box to modify the apriori standard deviations.
