Create New Geometry

When creating new geometry (e.g. VertexCreator), use the CoordinateSystemSetter transformer to define the coordinate system.

To change the geometry of a line (or polygon) into a single point at its start or end, you can use the Snipper transformer, setting the [Snipping Mode] to [Vertex], and setting the two indexes to [0] for the first vertex, or to [-1] for the last vertex:

To create a line or polygon from an array of coordinates, you can use the VertexCreator transformer with the [Mode] set to [Add Point]. However, this doesn't work if there are duplicate points other than start = end in the array.

Instead use the VertexCreator transformer with the [Mode] set to [Replace with Point], followed by a LineBuilder transformer. On the latter, make sure you connect the [Line] or [Polygon] output port!
