Curve Paths

To construct an open curve
, select the open curve tool, either by clicking on the open curve button or by selecting Tools->Open Curve (`Ctrl-K`).

To construct a closed curve
, select the closed curve tool, either by clicking on the closed curve button or by selecting Tools->Closed Curve (`Ctrl+Shift-K`).

Use the left mouse button to click on each vertex in the path. There is no way to specify the location of the
defining the curvature of the path whilst the path is under construction, however, once the path has been completed, it is possible to move these control points using the |
|.

To complete the path, do one of the following:

- Double-click instead of single-clicking on the final vertex: this performs the combined function of defining the vertex and finishing the path. If you use this method, be careful not to accidentally6.1 create two coincident vertices at the end point, or it will cause a problem for any mid or end |
  | that you apply.

- Single-click on the final vertex and then complete the path by pressing the `Enter` key or by clicking on the finish button or by selecting Tools->Finish.

If you have used the closed curve tool, the path will automatically be closed by inserting a curve between the end vertex and the initial vertex.

  You may, of course, want to do this intentionally, in which case ignore this caveat.
