Add points tool
Whilst the previously mentioned extend option only lets you add one point with a certain distance, the ADD POINTS TOOL lets you click your own points that make the extension of the curve. This option is especially usefull when 3d geometry is constructed with use of the curve. By using the history of the geometry, the adding of the points to the curve will take effect on the 3d geometry itself.
After adding the points for the extension you hit enter to finish the process.
