The Surface is where objects are arranged to create a custom control screen. Individual controls may be placed from the Control bar. Grouped sets of controls, representing typical multi-function system components, may be placed from the Object bar. The controls can then be customized and assigned to specific component functions within the system design using the Property Sheet. Customized or often-used controls can be copied to the Control Library for future placement into the Surface. Component objects may also be copied directly from the system design file into the Surface, where they will appear as appropriately grouped and assigned controls. There is also a Context Menu that is shown when right clicking on the surface or objects within it.
