Selecting Surface Elements

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 (Selectiemenu)

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

Alles selecteren.

None Alt-A

Niets selecteren.

Invert Ctrl-I

Selecteert alle geometrie die niet is geselecteerd en deselecteert momenteel geselecteerde componenten.

Select Random (Selecteer Willekeurig)

Reference (Referentie)

Mode (Modus):

Edit Mode (Bewerkingsmodus)

Menu:

Select ‣ Select Random

Select random control points.

Procent

Selects the defined percentage of control points.

Random Seed (Willekeurige Zaadwaarde)

Seed used by the pseudo-random number generator.

Action (Actie)

Controls whether the operator Selects or Deselects control points.

Checker Deselect (Patroon Deselecteren)

Mode (Modus):

Edit Mode (Bewerkingsmodus)

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) Gedeselecteerd

Het aantal gedeselecteerde elementen in elke patroonherhaling.

Selected (Geselecteerde)

Het aantal geselecteerde elementen in elke patroonherhaling.

Offset (Offset)

Offset van het startpunt.

Select Linked (Selecteer Gekoppeld)

Reference (Referentie)

Mode (Modus):

Edit Mode (Bewerkingsmodus)

Menu:

Select ‣ Select Linked

Shortcut (Sneltoets):

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 (Selecteer Vergelijkbaar)

Reference (Referentie)

Mode (Modus):

Edit Mode (Bewerkingsmodus)

Menu:

Select ‣ Select Similar

Shortcut (Sneltoets):

Shift-G

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

Type (Type)

Type (Type)

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

Radius

Selects control points that have a similar Radius value.

Weight (Gewicht)

Selects all points that have a similar Weight value.

Direction (Richting)

Selects control points that have a similar handles direction.

Compare (Vergelijken)

Voor kwantitatieve eigenschappen selecteert deze eigenschap het type vergelijking tussen de twee numerieke waarden.

Equal (Gelijk):

Selecteer items met dezelfde waarde als de gekozen eigenschap van het actieve item.

Greater (Groter):

Selecteer items met een grotere waarde als de gekozen eigenschap van het actieve item.

Less (Minder):

Selecteer items met een kleinere waarde als de gekozen eigenschap van het actieve item.

Threshold (Drempel)

Voor kwantitatieve eigenschappen bepaalt deze eigenschap hoe dicht de waarden van de eigenschap bij elkaar moeten liggen in de vergelijking.

Select Control Point Row

Reference (Referentie)

Mode (Modus):

Edit Mode (Bewerkingsmodus)

Menu:

Select ‣ Control Point Row

Shortcut (Sneltoets):

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 (Selecteer Meer/Minder)

Reference (Referentie)

Mode (Modus):

Edit Mode (Bewerkingsmodus)

Menu:

Select ‣ More/Less

Shortcut (Sneltoets):

Ctrl-NumpadPlus / Ctrl-NumpadMinus

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

More (Meer)

For each selected control point, select all its linked points (i.e. two, three or four).

Less (Minder)

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).
