Fills in polygons between boundary edges.
See also: Cap
This tool is useful for closing open geometry.
Select the edges of the polygon you want to cap.
You can select one edge and press L to loop forward and select all edges. Additionally, pressing R reverses the direction of the arrow and pressing F marches the selection forward once an edge is selected.
Click the PolyCap tool on the Polygon tab.
The cap is automatically fused to the polygon; however, there is an option to turn on the Unique Points checkbox in the parameter editor.
For specific parameter help see the PolyCap node help.
