Виділення – Selecting¶
This page discusses specific selecting tools for surface objects in Edit Mode. The Surface Edit more 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, B order-select, and so on.
Select Random¶
Орієнтир – Reference
Mode: | Edit Mode |
---|---|
Menu: |
Select random control points.
- Percent

Checker Deselect¶
Орієнтир – Reference
Mode: | Edit Mode |
---|---|
Menu: |
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.
- Nth Selection
- Skip every Nth element leaving it selected.
- Skip
- Number of consecutive elements to skip (keep selected) at once.
- Offset
- Offset from the starting point.
Виділити Пов’язане – Select Linked¶

Hotkey: | 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¶
Орієнтир – Reference
Mode: | Edit Mode |
---|---|
Menu: | |
Hotkey: | Shift-G |
Selects control points that have certain similar properties to the active one. The Наладнати Останню Операцію – Adjust Last Operation panel provides several selection options:
- 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
- Equal, Greater, Less. (only for Radius, Weight) (ToDo 2.76)
- Threshold
- Precision (ToDo 2.76)
Select Control Point Row¶
Орієнтир – Reference
Mode: | Edit Mode |
---|---|
Menu: | |
Hotkey: | 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¶
Орієнтир – Reference
Mode: | Edit Mode |
---|---|
Menu: | |
Hotkey: | Ctrl-NumpadPlus / Ctrl-NumpadMinus |
Expand or contract the selection based on current selected control points.
- Більше – More
- For each selected control point, select all its linked points (i.e. two, three or four).
- Менше – 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.
Це передбачає два моменти:
- Перше, коли усі керувальні точки поверхні виділені, то нічого не відбувається (оскільки для Less усі пов’язані точки завжди виділені, а, звичайно, More не може додати вже нічого). І навпаки, те ж саме відбувається, коли жодна з керувальних точок не виділена.
- Друге, ці засоби ніколи «не виходять за межі» поверхні (вони ніколи «не стрибатимуть» на іншу поверхню у цьому ж об’єкті).
