Use a Create Faces node () to create faces on an imported 3D mesh. Create Faces nodes are available from the Create Entities menu () on the Mesh ribbon or by right-clicking the main Mesh node.

Enter the properties for the Create Faces node using the following section:

To create faces you need to define an edge selection. If you select the Group adjacent edges check box (it is selected by default), then, when an edge is selected (or deselected), the selection automatically extends to neighboring edges that seem to be part of the loop. If you clear this check box, each edge can be selected (deselected) manually. To create faces, the selected edges must form simple loops; that is, there should be no ambiguity about how to draw the loops. You can select edges to form several loops in a single operation.
