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 sections:

To create faces you need to define an edge selection. 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. Only edges adjacent to void or unmeshed domains can be selected. 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.

Select the Create domains check box (selected by default) to automatically form domains for each (connected) finite void region that is defined by the imported surface mesh and analyze these domains with respect to the mesh that may already exist in the sequence. Clear the check box to not form domains, for example if more repairing is needed before the mesh forms watertight regions. Consider to later add a Create Domains operation if you clear the check box.
