--# For 2D pattern
- - A face having the number of vertices equal to the number of
- key-points in the pattern; the number of key-points on internal
- boundaries of a pattern must also be equal to the number of vertices
- on internal boundaries of a face;
- - A vertex to which the first key-point should be mapped;
- - Reverse or not the order of key-points. (The order of vertices of
- a face is counterclockwise looking from outside).
--# For 3D pattern
- - 3D block (Solid) object;
- - Two vertices that specify the order of nodes in the resulting
- mesh.
-
-Then you either load a .smp pattern file previously created manually
-by clicking on the <em>"Load pattern"</em> button, or click on the \b
-New button for automatic generation of the pattern.
-
-For an automatic generation you just specify a geometrical face (for
-2D) or solid (for 3d) having a mesh built on it. Mesh nodes lying on
-face vertices become key-points of 2D pattern. Additionally, for 2D
-pattern you may choose the way of getting nodes coordinates by
-<b>projecting nodes on the face</b> instead of using
-"positions on face" generated by mesher (if there is any). Faces
-having a seam edge can't be used for automatic pattern creation.
-
-When creating a pattern from an existing mesh, there are two possible
-cases:
-
-- A sub-mesh on face/solid is selected. A pattern is created from the 2d/3d
-elements bound to a face/solid by mesher. For 2D pattern, node coordinates are either
-"positions on face" computed by mesher, or coordinates got by node
-projection on a geometrical surface, according to the user choice. For
-3D pattern, nodes coordinates correspond to the nodes computed by mesher.
-- A mesh where the main shape is a face/solid, is selected. A pattern is
-created from all the 2d/3d elements in a mesh. In addition, for 2D
-pattern, if all mesh elements are build by mesher, the user can select
-the way of getting nodes coordinates, else all nodes are projected on
-a face surface.
