|Target Version||[OCCT] Unscheduled||Fixed in Version|
|Summary||0030528: Reduced data model with edges with an unique TEdges|
|Description||In case when shape contains many egdes sharing the same TEdge with different locations it would be useful to keep a single reference edge and locations within model's faces separately.|
This will potentially reduce amount of memory needed to keep model edges and reduce number of tesselation operations that can be performed several times for the similar edge.
|Tags||No tags attached.|
|Test case number|
|It is needed to analyze all consequences of such changes. E.g., if the same edge would get different subdivision depending on neighboring faces (if subdivision depends on curvature of the face) we will have to duplicate such edge anyway.|
|Or, take the maximal subdivision among all instances?|

Actually, BRepMesh considers geometry on neighboring faces to produce unified polygon suitable for entire set of faces sharing particular edge.
Another effect that we should be sure about in this case is correct orientation of an edge within face.
