external_edges is a module that draws lines corresponding to the edges of an object. The user interface panel for external edges has a parameter called edge angle. This angle is defined as the angle between two faces or cells in the model. If the angle is greater than the set edge angle, the edge is drawn. External edges are always drawn and setting the edge angle to 0 (zero) causes all cell boundaries to be drawn.
Locating the external_edges module
Scroll up (if necessary) to external_edges in Subsetting by clicking the up-arrow on the scroll bar. Scroll to the top of the list and you will see external_edges is the second module down in the list.
We can now see external_edges:
Instance external_edges
Instance external_edges. Point to external_edges; then, holding down the left mouse button, drag external_edges into the Application window .
Double click on external_edges to make its control panel visible. We'll modify the external edge angle before connecting it. (There is no real advantage to doing it first because this module is very fast, however for more complex modules and for larger models, we will avoid computing the output twice by selecting the parameter values before connection.)
Change the edge angle to 0 (zero) as in the example.
Connect external_edges to Krig_2D and Viewer
Connect external_edges to Krig_2D using the same Krig_2D (blue-black) output that is connected to plume_volume. All output ports can have multiple connections, but only a few input ports can. Viewer's red input port can have any number of inputs. Connect external_edges' red output port to the Viewer. At this point your network should look like this:
and your view should have changed
