Creating 3D Geometry Model

3D model may be created by one of two methods, depending on the model class:

For the problems with the model class "3D extrusion" 3D geometry model is created by the Z direction extrusion of the 2D objects in the XY plane;
For the "3D import" models 3D geometry is imported from the appropriate CAD program using the STEP format (ISO 10303).

The 3D View of the model editor is used for any 3D model handling after it is created by the extrusion or import. 3D view shows the model and allows assigning the labels to the model components - bodies, faces, edges and vertices, building the 3D finite element mesh with controlled density.

3D model manipulation includes using of the cross section plane for viewing and marking the internal objects, controlling the density and regularity of the finite element mesh inside the bodies, etc.

For creating a 3D model it should be linked to corresponding 3D problem. It is sufficient to have open 3D problem which refers to this model. If there is no such a problem - next steps are impossible.
