You can use the arrow keys ( , ) to
change the selection of edges to a full edge loop on a polygonal
mesh. You can then quickly change or walk the edge loop selection
along the mesh.
To select and then walk an edge loop
selection across a mesh
- Select either of the following:
- A full edge loop on the mesh.
You can select an edge
loop using
Select > Select Edge Loop Tool or
by Ctrl + right-clicking on the desired edge and choosing the Select
Edge Loop Tool from the Edge Loop Utilities marking
menu item.
- A single edge that is within the edge
loop you want selected.
NoteWhen you select a
single edge, you must click a second time using either the left
or right arrow keys to expand the selection to an edge loop.
- Continue to click either the left or
right arrow keys to change the selection to the neighboring parallel
edge loop along the mesh.
Clicking either key changes
the direction of the pick walk.
NoteClicking a key in
succession, walks the edge loop selection across the mesh until
it reaches and selects the border edges on the mesh. Continue to click
the same key to reverse the direction of the pick walk.
The following limitations
exist for edge loop selection with arrow keys:
- This feature works best when the initial
selection is either a single edge or edge loop. Otherwise, when
multiple edges are selected, the tool chooses a single edge loop
from the selection arbitrarily.
- The left and right arrow keys change
the direction of the pick walk, but may not be predictable in terms
of the initial pick walk direction in relation to the orientation
of the mesh.
- You cannot revert the edge selection
back to the initial selection state; that is, if you press left-arrow
to expand the edge selection to a full loop, pressing the right-arrow
will not select the original single edge.
- The up-arrow and down-arrow have no effect
on the edge loop selection or pick walk.
- To change the direction of the edge loop
selection once it has been selected, (the edge loop runs across
the mesh in a horizontal manner, and you want it to run in a vertical
manner) you must change the selection to a vertical edge or edge
loop.
