Selecting (Selecteren)

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

Curve selection in Edit Mode has fewer options than with meshes. Mainly this is, because there is only one selectable element type, the control points (no select mode needed here…). These points are a bit more complex than simple vertices, however, especially for Bézier curves, as there is the central vertex, and its two handles…

The basic tools are the same as with meshes, so you can select a simple control point with the LMB, add to current selection with Shift-LMB, Box Select B, and so on.

One word about the Bézier control points: when you select the main central vertex, the two handles are automatically selected too, so you can move it as a whole, without creating an angle in the curve. However, when you select a handle, only this vertex is selected, allowing you to modify this control vector…

Note that, unlike mesh edges, you cannot directly select a segment. Instead, select all of the control points that make up the segment you want to edit.

Select Random

Menu:

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 (Actie)

Controls whether the operator Selects or Deselects control points.

Checker Deselect

Reference (Referentie)

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

The number of deselected elements in each pattern repetition.

Selected

The number of selected elements in each pattern repetition.

Offset (Offset)

Offset from the starting point.

Select More/Less

Reference (Referentie)

Mode (Modus):

Edit Mode (bewerkingsmodus)

Menu:

Select ‣ More/Less

Shortcut (Sneltoets):

Ctrl-NumpadPlus, Ctrl-NumpadMinus

Their purpose, based on the currently selected control points, is to reduce or enlarge this selection.

More

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

Less

For each selected control point, if all points linked to this point are selected, keep this one selected. Otherwise, deselect it.

This implies two points:

1. When all control points of a curve 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 points are selected.

2. Second, these tools will never “go outside” of a curve (they will never “jump” to another curve in the same object).

Select Linked (Selecteer Gelinkte)

Reference (Referentie)

Mode (Modus):

Edit Mode (bewerkingsmodus)

Menu:

Select ‣ Select Linked

Shortcut (Sneltoets):

L, Ctrl-L, Shift-L

L (or Ctrl-L for all) will add to the selection the cursor’s nearest control point, and all the linked ones, i.e. all points belonging to the same curve. Note that for Bézier, using L with a handle selected will select the whole control point and all the linked ones.

Select Similar

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

Selects all points that have a similar Weight value.

Direction

Selects control points that have a similar handles direction.

Compare (Vergelijken)

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.

Threshold (Drempel)

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

(De)select First/Last

Reference (Referentie)

Mode (Modus):

Edit Mode (bewerkingsmodus)

Menu:

Select ‣ (De)select First, Select ‣ (De)select Last

These operators will toggle the selection of the first or last control point(s) of the curve(s) in the object. This is useful to quickly find the start of a curve (e.g. when using it as path…).

Select Next/Previous

Reference (Referentie)

Mode (Modus):

Edit Mode (bewerkingsmodus)

Menu:

Select ‣ Select Next, Select ‣ Select Previous

These operators will select the next or previous control point(s), based on the current selection (i.e. the control points following or preceding the selected ones along the curve). In case of a cyclic curve, the first and last points are not considered as neighbors.

Pick Shortest Path

Reference (Referentie)

Mode (Modus):

Edit Mode (bewerkingsmodus)

Menu:

Menu Search ‣ Pick Shortest Path

Shortcut (Sneltoets):

Ctrl-LMB

Selects the curve segments between two control points: the active and the one under the cursor. In the case of a closed curve, the shortest path will be selected.
