You can create a face by selecting the edges that the new face will cover. The selected edges must form a closed loop. Abaqus/CAE creates the new face as a shell. If the new shell forms a closed part, you can use the solid-from-shell tool to convert the part to a solid. For more information, see “Creating a solid feature from a shell,” Section 11.21.5. The cover edges operation is stored as a feature of the part; therefore, you can use the Model Tree to delete faces that you created. Abaqus/CAE creates the new face by projecting a face on the plane formed by the selected edges. Therefore, you should not use the Cover edges tool if the resulting face would be very convex.
To create a new face:
From the main menu bar, select Tools
Geometry Edit.
Abaqus/CAE displays the Geometry Edit dialog box.
Tip:
You can also create a face using the 
tool, located with the edit tools in the Part module toolbox. For a diagram of the edit tools in the toolbox, see “Using the Geometry Edit toolset,” Section 69.1.
From the dialog box, select the Face category and the Cover edges method.
Select the edges that form a loop and define the edges of the new face. You can select the edges from the viewport or select an existing set containing the edges. You can select more than one loop, and Abaqus/CAE will create more than one face. However, the loops should not be concentric.
Note: The default selection method is based on the selection method you most recently employed. To revert to the other method, click Select in Viewport or Sets on the right side of the prompt area.
From the prompt area, click Done.
Abaqus/CAE creates the new face.
If you have finished editing the part, you should check its validity by clicking mouse button 3 on the part in the Model Tree and selecting Update validity from the menu that appears.
