Selecting#

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

Select all.

None Alt-A

Select none.

Inverse Ctrl-I

Selects all the geometry that is not selected, and deselect currently selected components.

Box Select B

Interactive box selection.

Circle Select C

Select Similar Shift-G

Checker Deselect#

Reference

Mode:

Edit Mode

Menu:

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

The number of deselected elements in each pattern repetition.

Selected

The number of selected elements in each pattern repetition.

Deslocamento

Offset from the starting point.

Select Linked#

Reference

Mode:

Edit Mode

Menu:

Selecionar ‣ Selecionar vinculados(as)

Atalho:

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.

Selecionar por similaridades#

Reference

Mode:

Edit Mode

Menu:

Selecionar ‣ Selecionar por similaridades

Atalho:

Shift-G

Selects control points that have certain similar properties to the active one. The Adjust Last Operation panel provides several selection options:

Tipo
Tipo

Seleciona splines que tem o meu Tipo de spline, isto é, Bézier, NURBS ou Poly.

Raio

Seleciona pontos de controle que tem valor de Raio similares.

Weight

Seleciona todos pontos que tem valores de Peso similares.

Direção

Seleciona pontos de controle que tem uma direção de manípulo similar.

Comparação

For quantitative properties, this property selects the type of comparison to between the two numerical values.

Equal:

Select items with the same value as the active item’s chosen property.

Greater:

Select items with a larger value as the active item’s chosen property.

Less:

Select items with a smaller value as the active item’s chosen property.

Ajuste

For quantitative properties, this property controls how close the property’s values have to be in the comparison.

Select Control Point Row#

Reference

Mode:

Edit Mode

Menu:

Select ‣ Control Point Row

Atalho:

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.

Selecionar mais ou menos#

Reference

Mode:

Edit Mode

Menu:

Selecionar ‣ Mais / Menos

Atalho:

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:

  1. Primeiro, quando todos os pontos de controle da superfície estão selecionados, nada irá ocorrer (bem como ocorre com a opção Menos, todos os pontos vinculados estão sempre selecionados, e, obviamente, a opção Mais não poderá realizar mais adições). Conversivamente, o mesmo ocorre quando nenhum ponto de controles está selecionado.

  2. Segundo, estas ferramentas nunca irão «para fora» de uma superfície (elas nunca «saltarão» para outra superfície presente no mesmo objeto).
