SubSequenceOfEdges Struct Reference

This tool tries to unify faces and edges of the shape which lie on the same geometry. Faces/edges are considering as 'same-domain' if a group of neighbouring faces/edges are lying on coincident surfaces/curves. In this case these faces/edges can be unified into one face/edge. ShapeUpgrade_UnifySameDomain is initialized by a shape and the next optional parameters: UnifyFaces - tries to unify all possible faces UnifyEdges - tries to unify all possible edges ConcatBSplines - if this flag is set to true then all neighbouring edges, which lay on BSpline or Bezier curves with C1 continuity on their common vertices, will be merged into one common edge.

Detailed Description

This tool tries to unify faces and edges of the shape which lie on the same geometry. Faces/edges are considering as 'same-domain' if a group of neighbouring faces/edges are lying on coincident surfaces/curves. In this case these faces/edges can be unified into one face/edge. ShapeUpgrade_UnifySameDomain is initialized by a shape and the next optional parameters: UnifyFaces - tries to unify all possible faces UnifyEdges - tries to unify all possible edges ConcatBSplines - if this flag is set to true then all neighbouring edges, which lay on BSpline or Bezier curves with C1 continuity on their common vertices, will be merged into one common edge.

The input shape can be of any type containing faces or edges - compsolid, solid, shell, wire, compound of any kind of shapes. The algorithm preserves the structure of compsolids, solids, shells and wires. E.g., if two shells have a common edge and the faces sharing this edge lie on the same surface the algorithm will not unify these faces, otherwise the structure of shells would be broken. However, if such faces belong to different compounds of faces they will be unified.

The output result of the tool is the unified shape.

All the modifications of initial shape are recorded during unifying. Methods History are intended to:

• set a place holder for the history of modifications of sub-shapes of the initial shape;
  
• get the collected history.
  The algorithm provides a place holder for the history and collects the history by default. To avoid collecting of the history the place holder should be set to null handle.
