Offset by Point & Alignment

(This functionality is available with the Computations module)

Creates a new offset object between an existing point and an alignment.

To run this option, select the Create/Offset command and the Method/Point & Alignment command from the Computations task to display the relevant dialog box.

The offset line to be created will be given the attributes currently defined via the Attributes/Line command.

If the offset point is located near the bend of the alignment it is offset from, then this will cause the offset line to be created to the corner point.

Create Offset by Point & Alignment dialog box

Item	Used to
Alignment:	Select an existing alignment that the point is to be offset from. Alternatively, you may snap to and accept an existing alignment.
Point ID:	Key in an existing point identifier to be used as the offset point. Alternatively, you may snap to and accept an existing point.
Apply:	Creates the offset from the point to the alignment.
Cancel:	Closes the dialog.

Note:

The offset objects created using this method are tied very closely to the alignment they are offset to. For example, if the alignment is deleted the offset will also be deleted, or if the alignment is moved, the offset will update. Also if the point in the offset is moved, this will also cause the offset to update with respect to the alignment.

If the alignment is edited, this will cause the offset to be reconstructed/updated. But if, for example, the point is beyond the ends of the alignment, then the offset will be deleted.
