Another way to prevent polygons at the back from being selected is to switch on backface culling,
which hides these polygons from the viewport. In addition, you can also hide polygons to prevent
them from being selected using the Hide Selected and Hide Unselected commands from the Selection
menu. Lastly, set an object’s top visibility dot to red to hide that object and to prevent its elements
from being selected. (You’ll nd the visibility dots in the Object manager, next to the object’s icon.)
Tolerant Selection (Rectangle Selection, Freehand Selection, Polygon Selection)
This option makes sense only in polygon mode. Enabling the option means that an edge or polygon
will be selected if any part of it is inside the selection marquee. If the option is disabled, the polygon
or edge will only be selected if all of its corner points are inside the marquee.
Tolerant Edge Selection / Polygon Selection
This option applies to edge and polygon modes. If the option is enabled, an edge or polygon will be
selected if the Live Selection tool touches any part of it. If the option is disabled, the edge or polygon
will only be selected once 75% or more of it has been painted.
Mode (Live Selection)
Normal
This is the standard mode for the Live Selection tool. It hides away the vertex painting and soft
selection settings.
Vertex Painting
You can also set vertex weights using the Set Vertex Weight command
(Selection menu).
You can use the Live Selection tool not only to select but also to paint vertex maps or weights. Select
the Points tool and drag over the vertices to paint them.
To see the weighting in color, ensure the viewport’s display is set to Gouraud Shading or Quick
Shading. In addition, you can choose if the Live Selection should paint a specic weight or whether
it should lighten or darken the existing weighting (set Mode to the desired operation: Set, Add or
Subtract — Strength denes how much weight to set, add or subtract).
