3D BSpline Surface Edit Mode

Makes the point following in the cross-wise direction the current active point active.

Makes the point preceding in the cross-wise direction the current active point active.

Makes the point following in the length -wise direction the current active point active.

Makes the point preceding in the length-wise direction the current active point active.

Activates the point nearest to the cursor.

Point is moved continuously, so that the x and y coordinates change while z remains constant.

Point is moved continuously, so that the z coordinate changes while x and y remain constant.

Changes the coordinates of the active point by entering numeric parameters for the coordinates of the point.

Changes the coordinates of the active point by adding values entered as numeric parameters to the coordinates of the point. This has the effect of moving the point by the amount entered.

Picks a cross-wise curve of the surface for curve editing on a plane. The chosen curve is the one that goes through the active point, or, if the control mesh is being edited, the nearest cross-wise section.

Picks a length-wise curve of the surface for curve editing on a plane. The chosen curve is the one that goes through the active point, or, if the control mesh is being edited, the nearest cross-wise section.

Any action that changes the curve may be canceled by clicking this icon immediately after the erroneous action. Only the last one action can be canceled by this command.

Erases the screen and redraws the contents. This may be needed to clean up the display after graphical moving.

Finishes editing the surface and saves the edits.

Finishes editing the surface but does not save the surface. All edits made will be discarded.

Makes the point following in the cross-wise direction the current active point active.

Makes the point preceding in the cross-wise direction the current active point active.

Makes the point following in the length -wise direction the current active point active.

Makes the point preceding in the length-wise direction the current active point active.

Changes the coordinates of the active point by entering numeric parameters for the coordinates of the point.

Changes the coordinates of the active point by adding values entered as numeric parameters to the coordinates of the point. This has the effect of moving the point by the amount entered.

Changes the coordinates of the active point by entering numeric parameters for the coordinates of the point. Neighboring points will not change so this function may produce a sharp corner.

Picks a length-wise curve of the surface for curve editing on a plane. The chosen curve is the one that goes through the active point, or, if the control mesh is being edited, the nearest cross-wise section.

Inserts a new curve on the surface. Point and click with the left mouse button where you want to add the new curve. The system asks whether you want to add a cross-sectional curve, a lengthwise curve or both.

Any action that changes the curve may be canceled by clicking this icon immediately after the erroneous action. Only the last one action can be canceled by this command.

Erases the screen and redraws the contents. This may be needed to clean up the display after graphical moving.
