class Loop2d from Partition
|

|
|

|
|
---Purpose: Builds the loops from a set of edges on a face.
|
||
|
|
-- It works in supposition that all constant edges
|
||
|
|
-- are split edges of an initialization face and all
|
||
|
|
-- section edges are new on the face
|
||
|
|
|

|
|
---Purpose: Build faces from the wires result.

-- <EdgeImage> serves to find original edge by new

-- one.
