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.

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

Deselected

Selected

The number of selected elements in each pattern repetition.

Offset (смещение)

Offset from the starting point.

Select ‣ Select Linked

Горячая клавиша:

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 ‣ Select Similar

Горячая клавиша:

Shift-G

Selects control points that have certain similar properties to the active one. The Настройки последней операции panel provides several selection options:

Type

Type

Selects splines that have the same spline Type i.e. Bézier, NURBS or Poly.

Radius (радиус)

Selects control points that have a similar Radius value.

Weight (вес)

Selects all points that have a similar Weight value.

Direction

Selects control points that have a similar handles direction.

Compare (сравнение)

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

Equal (равно):

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.

Threshold

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

Select Control Point Row

Справка

Mode:

Режим редактирования

Меню:

Select ‣ Control Point Row

Горячая клавиша:

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

Справка

Mode:

Режим редактирования

Меню:

Select ‣ More/Less

Горячая клавиша:

Ctrl-NumpadPlus / Ctrl-NumpadMinus

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

Прочие узлы

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. 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.

2. Second, these tools will never «go outside» of a surface (they will never «jump» to another surface in the same object).
