LineCloser
Turns input linear features into areas by adding their start point as the end point.
Note: Use this transformer with care: the result may self-intersect.
Parameters
When viewed in 2D (ignoring Z), a path (which may define the border of a polygon) may appear to be closed as shown in the left figure below. This same path, when viewed in 3D, may appear to be open as shown in the right figure below.
To specify how (and if) paths should be closed in 3D, select one of the listed modes.
Mode | Description | Example |
---|---|---|
Extend | The Curve is extended so that all vertices are left at their original location. | |
Average | Subsequent vertices that are not connected, but share an x and a y value are combined into one vertex, whose Z value is the average of the original two. | |
First Wins | Subsequent vertices that are not connected, but share an x and a y value are combined into one vertex, whose Z value is taken from the first encountered vertex. | |
Last Wins | Subsequent vertices that are not connected, but share an x and a y value are combined into one vertex, whose Z value is taken from the last encountered vertex. | |
Ignore | Z values are ignored. No change is made to the way the nodes are connected. |

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
