Use Create Faces () to create meshed boundaries within selected edges in a surface mesh in 3D, as shown in Figure 8-49. The generated face will be as close to planar as possible.

To add a Create Faces node, select edges in the Graphics window, then choose one of the following:

Enter the properties for Create Faces using the following sections:

To create faces you need to define an edge selection. The selected edges must form simple loops; that is, there must 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 checkbox (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 checkbox, each edge can be selected (deselected) manually.

Select the Create domains checkbox (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 might already exist in the sequence. Clear the checkbox 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 checkbox.

Select the Resulting faces and/or the Resulting domains checkboxes to create predefined selections in subsequent nodes in the mesh sequence. To also make the selections available in all applicable selection lists in physics and materials settings, for example, select the Show in physics (Show in instances if in a mesh part) checkbox. These selections do not appear as separate selection nodes in the model tree. From the Color list, choose a color for highlighting the resulting objects selection.
