Creating patterns

- -

The pattern description can be created manually or automatically. Manual - pattern creation implies creation of pattern file by hands. For an automatic - generation the user just specifies a geometrical face having a mesh built - on it. Mesh nodes lying on face vertices become key-points. Additionally, - the user may choose the way of getting nodes coordinates by projecting - nodes on the face instead of using "positions on face" generated - by mesher (if there are 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:

- -

 

- -

1. A sub-mesh on face is selected. A pattern is created from the 2d - elements bound to a face by mesher. Node coordinates are either "positions - on face" computed by mesher, or coordinates got by node projection - on a geometrical surface, according to your choice.

- -

 

- -

2. A mesh where the main shape is a face, is selected. A pattern is - created from all the 2d elements in a mesh. 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.
