AdvClearMidVtsDelete the verts which has only two edges,but that verts which angel is smaller than threshold value will be ignore.

SnapZ | ZMove |SnapToP


SnapZSnap a point and set all z coordinates of selected vertices to z value of the point coordinates.
ZMoveSnap two points ,move selected vertices in Z-AXIS from first point to second one.

MoveOnDir|FlattenEgs |RightAgl|ClearChaosEgs


MoveOnDirSnap two points as direction, which the selected verts will move along on moving mouse.
FlattenEgsOne by one make each of selected edges flat.
RightAglOne by one ,make each selected edge perpendicular to an arbitrary adjcent edge.
ClearChaosEgsClear these co-plane edges which can cause visual chaos.
