Selecting Surface Elements

When editing a Surface object, it’s only possible to select control points. There are no edges, faces, or Bézier handles.

Menu:

Select ‣ Select Random

Adds random control points to the selection. The Adjust Last Operation panel offers the following options:

Ratio

The ratio of control points that should end up selected, e.g. 0.5 to select half of all points (that are not hidden).

Note that the existing selection is ignored: if half of the control points are already selected, setting Ratio to 0.1 won’t deselect anything, nor will it select 10% of the unselected points. Instead, it always picks 10% of all visible points and adds them to the selection.

Random Seed

A number that influences which specific control points get picked.

Action

Select:

Add random control points to the selection.

Deselect:

Remove random control points from the selection.

Checker Deselect

Reference

Mode:

Edit Mode

Menu:

Select ‣ Checker Deselect

Deselects control points according to a repeating pattern, starting at the active point. For example, if Deselected is set to 2 and Selected to 3, the operator will deselect the first two consecutive points, leave the next three unchanged, deselect the two that come after those, and so on. This is done in both the “horizontal” and “vertical” direction of the grid.

Deselected

The number of control points to deselect in each pattern repetition.

Selected

The number of control points to leave unchanged in each pattern repetition.

Offset

Offset from the starting point.

Select More/Less

Edit Mode

Menu:

Select ‣ More/Less

Shortcut:

More

Adds the neighbors of the selected control points to the selection.

Less

Removes the control points with at least one unselected neighbor from the selection.

Select Linked

Select ‣ Select Linked

Shortcut:

Ctrl-L, L

Press Ctrl-L to select all control points that are “linked to” (belong to the same surface as) a control point that’s already selected.

Alternatively, press L to select the control point under the mouse cursor and all control points that are linked to it.

Select Similar

Reference

Mode:

Edit Mode

Menu:

Select ‣ Select Similar

Shortcut:

Shift-G

Selects control points that are similar in some way to a selected control point. The Adjust Last Operation panel provides options for this:

Type

Which property to compare for determining similarity.

Type:

This option does not apply for Surfaces because, unlike Curves, they only support one handle type.

Radius:

Selects control points that have a similar Radius value. See Transform Panel.

Weight:

Selects control points that have a similar Weight value. See Transform Panel.

Direction:

Selects control points that have a similar normal vector.

Compare

How to compare unselected control points to selected ones.

Equal:

Select control points whose property is equal to that of a selected point.

Greater:

Select control points whose property is greater than or equal to the smallest property among the selected points.

Less:

Select control points whose property is less than or equal to the greatest property among the selected points.

Threshold

Tolerance value for also including control points whose property is close to the property of a selected point. For example, if a selected control point has a Weight of 0.6 and the Threshold is set to 0.1, Select Similar will include all control points that have a Weight between 0.5 and 0.7.

Select Control Point Row

Reference

Mode:

Edit Mode

Menu:

Select ‣ Control Point Row

Shortcut:

Selects the control points that are on the same grid line as the active one (similar to edge loop selection for meshes). Invoke the operator again to use the grid line in the other direction.
