Flat Pattern (二维展开)

?Traverse ControlAlgorithm

Sheet Metal----Select the Sheet Metal traversal algorithm for parts that reflect a formable manufacturing process, and typically exhibit a uniformthickness. The algorithm identifies pairs of faces that are separated by a uniform thickness.

Generic ----When flat representations are required for parts where theconcept of thickness does not apply, better results are obtained with theGenericalgorithm

Woven Material(编织材料) ----Use this option when you want to flatten apart made of woven materials such as composites. With this option only the selected start face is flattened. Addition faces cannot be selected. Youmay select additional curves and/or points to project to the flat pattern in Layout Options.

None ----Select None when you want to flatten only the start face or a subset of faces of the body. You may then select additional faces to flattenin Layout Options. You must insure that the additional faces you select are connected somehow to the start face. Setting the Traversal Control to None will also prevent traversal of the part during automatic update.

?Area Preserving Faces----Most of the faces in the flat pattern are of thistype.

?Distortion Faces----You may not want some faces to be flattened as area-preserving. Instead the face may need to distort when formed, and not preserve its area. A case where you may want a distortion face, is when the face must stretch, compress, or buckle when the part is formed.

?Projection Faces----This solver is used to project its assigned face onto the flat pattern plane without distorting adjacent faces. Bead faces are examples of projection-typed faces.

?Cutting Edges ----In some cases, adjacent faces in the body are not intended to be adjacent in the flat pattern. To separate the faces, you may select edges where the flat pattern is to be cut.
