Whats the difference between mate and planar alingnment relationship commands in solid edge?
Why there are two diff commands mate and planar alignment when perform same operations?how different are they?
Mate and planar are different: Mate is when two faces are aligned with their normals on opposite directions; Planar is when two faces are aligned with their normals on the same direction. Imagine a book: when you open it on top of a table, two pages are shown and pointing out in the same direction (planar); if you now close the book, those two pages are now facing opposite directions (mate).
