/*! \page use_existing_page Use Edges/Faces to be Created Manually The algorithms Use Edges to be Created Manually and Use Faces to be Created Manually allow creating a 1D or a 2D mesh in a python script (using AddNode, AddEdge and AddFace commands) and then using such sub-meshes in the construction of a 2D or a 3D mesh. For example, you want to use standard algorithms to generate 1D and 3D meshes and to create 2D mesh by your python code. For this, you
  1. create a mesh object, assign a 1D algorithm,
  2. invoke \b Compute command, which computes a 1D mesh,
  3. assign Use Faces to be Created Manually and a 3D algorithm,
  4. run your python code, which creates a 2D mesh,
  5. invoke \b Compute command, which computes a 3D mesh.
\warning Use Edges to be Created Manually and Use Faces to be Created Manually algorithms should be assigned _before_ mesh generation by the Python code. Consider trying a sample script demonstrating the usage of \ref tui_use_existing_faces "Use Faces to be Created Manually" algorithm for construction of a 2D mesh using Python commands. \image html use_existing_face_sample_mesh.png Mesh computed by \ref tui_use_existing_faces "the sample script" shown in a Shrink mode. */
