Selection Options (Filters)
This option shows the Selection Filters dialog. This is helpful for complicated crease and other edge-based operations where a large number of sub-objects are involved. The choices are as follows:
Keep Co-planar Edges: keep only edges in selection list which are between two control mesh faces which lie on the same plane.
Remove Co-planar Edges: keep only edges in selection list which are NOT between two control mesh faces that lie on the same plane.
Keep All Weighted Edges: removes all edges from selection set which have edge weight of zero value
Keep 100% Weighted: removes all edges from selection set which have edge weight less than 100%
Keep Partial Weighted: removes all edges from the selection set which have an edge weight of zero or 100%.
Select Within Boundary: Given a face that is selected within a boundary, this option will select all of the faces within that boundary.
Select Edges Around Faces: selects the set of edges which border a face selection.

Selecting the top edges, (left image), the edge selection used in the following examples, (center image). Note the corner vertex dropped lower. The top outer edge weights set at 20, the top center edge set to 100 and the other two top edges set to 0, (right image).
The selection with non-zero weighted edges remaining, (left image), only edges with a weight of 100% remaining, (center image), and only partial weighted edges, e.g., between 0 and 100, (right image).
Select Within Boundary
Selects all faces within the boundary of the selected face. You will need to utilize the Define Boundary command to create boundaries from groups of faces.
Select Edges Around Faces
Selects all edges bordering one selected face and one non selected face. The left image below shows the initial face selection and the second shows the result of Select Edges Around Faces.
