Insert PointInsert Point Within Range

Availability: Computations module.
Menu Selection: From the Computations task, select the Edit command and the Insert Point Within Range... command.
Functionality: existing line object
Controls:
  • Insert Point [Existing]
  • Offset Range (+/-) [Enter the search distance for points that are to be inserted into a line. A non negative number must be entered for the range, the default is zero which means the point is abutting.
    Example: A range of 1 metre will define a search area 1 metre to the left and 1 metre to the right of a line that the point lies within.]
  • Check the Break Line at Point checkbox to break the line into which the point is being inserted at the insertion point.
  • Check the Move Line to Point checkbox to move the line to pass through the point, otherwise the point is moved by offset onto the line.
Actions:
  • If the point selected is within the offset range of a line, the Insert Button inserts the selected insertion point into the selected line segment. If the line moves to the point that will thereby amend the geometry of that line, otherwise the point will be moved in a perpendicular direction to the line, onto the line. The line attributes remain unchanged, except that it cannot remain contourable if the insertion point is not contourable.
Notes:
  • If the amended line is part of a polygon, then the polygon remains intact with only its vertices added to, but not its area or shape being altered.
  • If a line is to be modified such it will become invalidated, then a message will be displayed and the process aborted.
  • If a construction point is to be modified such it will invalidate another object, then a new construction point will be inserted to maintain object integrity.
  • This command is display and block sensitive and hence is a quick way of inserting all abutting points into lines for a desired region.
  • To remove overlapping lines from a region, define the required block and use this command with the "Break" option active, then delete any polygons and filter the lines.
