To control the net display, select the items under the Net submenu in the Display menu.

Show Net

The entire network of control points is shown by itself.

Hide Net

In Perspective, Profile and Plan window only the edges of the surface will be shown. If you wish to hide the edges you should hide or lock the surface.

In Body Plan window, the current control points column of the Current Surface will be displayed. This allows you to adjust the shape of one column at a time. See also Body Plan Window on page 31.

Only Rows are displayed.

Columns

In cases where you are dealing with a complex net of control points, it is sometimes very helpful to be able to select a particular group of control points to remain visible while the remainder of the net is hidden. This is the function of the Mask command.

It can be particularly useful to select the control points you wish to mask in one view and then to manipulate them in another view. For example, when fairing a bulbous bow, it can be helpful to mask the control points in the Perspective or Profile views and then manipulate the surface shape in the Plan view.

When working with a control point net with a large number of columns, it may be very confusing to try to work on particular points in the Body Plan window.

By selecting all the points on one or two columns and then selecting Mask, only the portion of the net selected, and the area of the surface that it exerts an influence on, will be displayed. It will then be much easier to view and modify in the Body Plan or any other window.

When the Unmask command is selected, the entire net will be made visible again.
