Surface ‣ Spin

Similar to its mesh counterpart, this operator extrudes the selected control points several times along a circle that’s centered on the 3D Cursor and parallel to the viewing plane. The weights of the new control points are set up to produce a circle, and the surface is marked as Cyclic , Bézier , and Endpoint in the extrusion direction (see Active Spline).

Add Duplicate

Reference

Mode:

Edit Mode

Menu:

Surface ‣ Add Duplicate

Shortcut:

Shift-D

Duplicates the selected control points and creates a new surface based on them. The new control points are placed in the Move mode: move the mouse to bring them to the desired position, then click LMB to confirm. Alternatively, press RMB or Esc to keep them at their original position.

Note that the selected control points must form a single, valid sub grid. If this is not the case, the duplication will fail with an error.

Split

Reference

Mode:

Edit Mode

Menu:

Surface ‣ Split

Shortcut:

Y

Disconnects the selected sub grid from the rest of the surface, keeping it within the same Surface object. The control points at the border are duplicated so that both the original surface and the disconnected surface have them.

The sub grid must consist of one or more complete rows or columns of the surface grid.

Separate

Reference

Mode:

Edit Mode

Menu:

Surface ‣ Separate

Shortcut:

P

Disconnects the selected sub grid from the rest of the surface and moves it into a new Surface object. The control points at the border are duplicated so that both the original surface and the disconnected surface have them.

The sub grid must consist of one or more complete rows or columns of the surface grid.

Toggle Cyclic

Reference

Mode:

Edit Mode

Menu:

Surface ‣ Toggle Cyclic

Shortcut:

Alt-C

Opens a popover menu with the options Cyclic U and Cyclic V. The surface is made cyclic (closed) or non-cyclic (open) in the corresponding direction.

If a surface is cyclic, the last row or column of its control point grid is connected back to the first. A cylinder is cyclic along either the U or V direction, while a sphere is cyclic along both.

The Cyclic settings are also in the Active Spline panel in the Sidebar.

Shortcut:

H, Shift-H, Alt-H

Hides the selected or unselected control points, or unhides all hidden control points.

By default, unhiding control points adds them to the selection. To prevent this, uncheck the Select option in the Adjust Last Operation panel.

Delete

Reference

Mode:

Edit Mode

Menu:

Surface ‣ Delete

Shortcut:

X, Delete

Removes the selected Vertices (control points) or Segments (lines) from the surface. In both cases, the selection must consist of one or more complete rows or columns of the surface grid.

Vertices

Deletes the selected control points. The resulting gap is bridged with new grid lines so that the surface stays contiguous.

Segments

Deletes the lines and control points that lie between the outermost selected control points. The resulting gap is not bridged.

Dissolve Vertices

This feature only works for Curves.
