Border
edges are the edges that lie either on the exterior or
interior perimeter of a polygon mesh. Border edge selection works
in a manner similar to the ring and edge loop selection types. Depending
on which edge you initially select (exterior or interior), the associated
border edges along the polygon mesh get selected.
Border edge selections
save you from having to select each border edge individually.
To select interior and exterior border
edges on a polygonal mesh
- In the scene view, select the polygonal
mesh upon which you want to select the border edges.
The selected polygonal
mesh highlights in a green color.
- From the Polygons menu
set, choose
Select > Select Border Edge Tool.
The selected polygonal
mesh highlights in a blue color to indicate edge selection
mode.
- If you want to select the exterior border
edges for the mesh, double-click on an exterior edge of the polygon
mesh.
The exterior border edges
on the mesh become selected.
- If you want to select the interior border
edges on the mesh, double-click on an interior edge of the polygon
mesh.
The interior border edges
on the mesh become selected.
- If you want to cancel the selection of
a particular edge, + on the
desired edge. If you want to cancel the edge selection entirely,
click anywhere in the scene view off of the mesh.
NoteYou can also click
border edges to create a partial border selection. For example,
if you click one exterior border edge and then click a second exterior
border edge that is connected through the border edges along the
mesh, the border edge segment between the first and second click
will be selected. See the diagram below.
TipIf you need to perform
a lot of edge selection you can view the Tool Settings and easily
switch between the various edge selection modes without having to
repeatedly select the tool items from the Edit menu.
