+ It is possible to define a 1D or a 2D mesh in a python script and then \r
+ use such submeshes in the construction of a 3D mesh. For this, there exist \r
+ two algorithms: <span style="font-weight: bold;"><B>Use existing edges</B></span> \r
+ and <span style="font-weight: bold;"><B>Use existing faces</B></span>. They are \r
+ not entirely usable from the GUI, so a mesh created using these algorithms \r
+ should be exported into a python script, edited and then imported into \r
+ the GUI. </td>\r
