In this rollout everything dealing with
edges is handled:
Div:
Divide edges. Similar to Edit Mesh.
Cut: Cut Edges. Similar
to Edit Mesh.
SlicePl/Slice: Slice
Plane. Similar to Edit Mesh.
Turn: Turn Edges.
Similar to Edit Mesh.
Flip: "Flip" Edges.
This means all polygons bordering this edge are flipped. Useful when creating new polys by shift-dragging edges.
VisMode: Sets eges
visible or invisible with one click. Clicking with Shift key pressed
deselects.
Extr: Extrude. Similar to
Edit Mesh.
Local: Extrude Normal
local. Similar to Edit Mesh's Normal:Group/Local Option.
Cham: Chamfer. Similar to
Edit Mesh.
Visible: Set selected
edges visible. Similar to Edit Mesh.
Invisible: Set selected
edges invisible. Similar to Edit Mesh.
AllVis: All edges
visible.
AllInvis: All edges
invisible.
MatVis: All edges, where
the material id change, become visible, plus the border. All others
become invisible.
TileVis: All edges,
where the material id change, where the mapping changes, plus the
border become visible. All others become invisible.
This won't work correctly in some cases of mirrored textures.
Edges before (all visible)
Edges after MatVis - texture ID borders
become visible
Edges after TileVis - texture ID borders
and texture tiling becomes visible
SelOpen: Select open
edges. Similar to Edit mesh. This button has become more or less
obsolete, because of the "Open" button in the selection panel.
This button always selects the invisible edges too (in opposite to the
"Open"-button, where invisible edges are not selected (if object has
"Edges Only" flag).
BorderVis: All
edges on the border (open edges) become visible, all other invisible.
