-<h2>"Use existing edges" and "Use existing faces" algorithms</h2>
-
-It is possible to create a 1D or a 2D mesh in a python script
-(using <em>AddNode, AddEdge</em> and <em>AddFace</em> commands) and
-then use such sub-meshes in the construction of a 2D or a 3D mesh. For
-this, there exist two algorithms: <b>Use existing edges</b> and <b>Use
- existing faces</b>.
-For example, you want to use standard algorithms to generate 1D and 3D
-meshes and to create 2D mesh by your python code. Then you
-<ol>
- <li> create a mesh object, assign an 1D algorithm,</li>
- <li> invoke \b Compute command, which computes an 1D mesh,</li>
- <li> assign <b>Use existing faces</b> and a 3D algorithm,</li>
- <li> run your python code, which creates a 2D mesh,</li>
- <li> invoke \b Compute command, which computes a 3D mesh.</li>
-</ol>

-Consider trying a sample script demonstrating the usage of
-\ref tui_use_existing_faces "Use existing faces" algorithm for
-construction of a 2D mesh using Python commands.
