Selección

This page discusses specific selecting tools for surface objects in Edit Mode. The Surface Edit also uses the general select tools used which are described in the interface section.

Surface selection in Edit Mode is very similar to NURBS curve selection. The basic tools are the same as with meshes, so you can select a simple control point with an LMB-click, add to current selection with Shift-LMB clicks, Border Select, and so on.

Select Menu

The Select menu (in the 3D Viewport header) is even simpler than for curves…

All these options have the same meaning and behavior as in Object Mode and mesh Edit Mode.

All A: Seleccionar todo.
None Alt-A: Seleccionar nada.
Inverse (Invertir) Ctrl-I: Selects all the geometry that is not selected, and deselect currently selected components.

Selección de Caja B: Interactive box selection.
Circle Select C: Interactive circle selection.
Lasso Select: Interactive free-form selection.

Select Random: Select random control points.
Checker Deselect: Select every Nth control point.
Select Linked Ctrl-L: Select control points that are connected to the current selection.
Select Similar Shift-G: Select control points that have similar properties to the current selection.

Select Control Point Row: Select a whole row of control points.

Select More/Less: Select objects based on their parent child relationships.

Select Random

Referencia

Modo: Modo Edición
Menú: Select ‣ Select Random

Select random control points.

Percent: Selects the defined percentage of control points.
Random Seed: Seed used by the pseudo-random number generator.
Action: Controls whether the operator Selects or Deselects control points.

Checker Deselect

Referencia

Modo: Modo Edición
Menú: Select ‣ Checker Deselect

This tool applies an alternating selected/deselected checker pattern. This only works if you already have more than one control point selected.

It works by changing the current selection so that only every Nth control points will remain selected, starting from the active one.

Deselected (Deseleccionados): The number of deselected elements in each pattern repetition.
Selected (Seleccionados): The number of selected elements in each pattern repetition.
Offset: Desplazamiento desde el punto de inicio.

Seleccionar Vinculado

Referencia

Modo: Modo Edición
Menú: Select ‣ Select Linked
Atajo: L, Ctrl-L

Select Linked will add to the selection the mouse cursor’s nearest control point, and all the linked ones, i.e. all points belonging to the same surface.

Select Similar

Referencia

Modo: Modo Edición
Menú: Select ‣ Select Similar
Atajo: Shift-G

Selects control points that have certain similar properties to the active one. The Ajustar la Última Operación panel provides several selection options:

Tipo

Tipo: Selects splines that have the same spline Type i.e. Bézier, NURBS or Poly.
Radius (Radio): Selects control points that have a similar Radius value.
Weight: Selects all points that have a similar Weight value.
Direction: Selects control points that have a similar handles direction.

Compare

Equal, Greater, Less. (only for Radius, Weight) (ToDo 2.76)

Threshold

Precision (ToDo 2.76)

Select Control Point Row

Referencia

Modo: Modo Edición
Menú: Select ‣ Control Point Row
Atajo: Shift-R

This option works a bit like edge loop selection for meshes, inasmuch it selects a whole row of control points, based on the active (the last selected) one. The first time you press Shift-R, the V row passing through (containing) the active point will be added to the current selection. If you use again this shortcut, you will toggle between the U and V row of this point, removing everything else from the selection.

Select More/Less

Referencia

Modo: Modo Edición
Menú: Select ‣ More/Less
Atajo: Ctrl-NumpadPlus / Ctrl-NumpadMinus

Expand or contract the selection based on current selected control points.

More: For each selected control point, select all its linked points (i.e. two, three or four).
Less: For each selected control point, if all points linked to this point are selected, keep it selected. For all other selected control points, deselect them.

This implies two points:

First, when all control points of a surface are selected, nothing will happen (as for Less, all linked points are always selected, and of course, More cannot add any). Conversely, the same goes when no control point is selected.
Second, these tools will never «go outside» of a surface (they will never «jump» to another surface in the same object).
