This type of plane is perpendicular to one of the co-ordinate axes.

Figure 2:27. Form for creation and modification of principal plane.
The Axis field: If you select X for instance, then the plane will be perpendicular to the x-axis.
The Coord field: Here you give one or several co-ordinate values, for example, "FR40(10)80", "FR40,FR50,FR60". (If Axis is set to X then the Coord field contains co-ordinate values along the x axis and ditto for the y and z axes).
The Select Type button: Lets you change the type of the plane to any of the plane types described in this section. This button is only displayed when modifying an existing plane.
The Apply button: Create a plane with the given input, but keep the form open. This is practical if several planes are to be created at the same time. This button is only displayed when creating a new plane.
The Ok button: Accept the input and create a new plane or modify an existing one according to the input.
The Cancel button: Exit the function without creating or modifying any plane.
