Insert Point in Line or Spline

Availability:	Computations module and the 3D Visualisation module.
Menu Selection:	From the Computations task or the 3D Visualisation module, select the Edit command and the Insert Point...command.
Functionality:	existing point
Controls:	Insert Point [Existing] into Line [Existing] between Point [Existing] and Point [Existing]
Actions:	Check the Break Line at Point Checkbox to break the line into which the point is being inserted at the insertion point. The Insert Button inserts the selected insertion point into the selected line segment, thereby amending the geometry of that line. The line number and its attributes remain unchanged, except that it cannot remain contourable if the insertion point is not contourable.
Notes:	If you snap to a line or spline, the line points at either end of the selected line segment are automatically set in the following point identifier fields. If the line object selected is other than a line or spline, the point must lie on object and the between Point and Point identifiers are redundant. If the amended line is part of a polygon, then the polygon remains intact with only its geometry and area being altered. In fact, this command is particularly useful for amending the geometry of polygons.
