Adding polyhedrons

        

 

There are two different ways to add polyhedral volumes.

If you select Node as Elements Type you will specify the nodes which will form the faces of your polyhedron by selecting the nodes in the 3D viewer with pressed Shift button and clicking the Add button to add the face in the list of Faces by Nodes, which will form your polyhedron. Note, that it could be very useful to toggle Polyhedron Preview checkbox to see the results of your selection.

The second way is somewhat simpler, however, there are cases when it does not provide you with the necessary level of precision. If you select Face as Elements Type, you will be able to select the faces  which will form your polyhedron in the 3D viewer with pressed Shift button. If you've managed to

obtain the necessary result, click the Apply or OK button. Your hexahedron will be created.
