Four Point Surface Use the Four Point Surface command to create a surface by specifying four points. This is useful for creating base surfaces that support the surface based Class-A workflow. You can easily modify such a surface by increasing the degree and patch into a more complex surface with the desired shape. You must follow these point specifying conditions No three selected points can be collinear. No two selected points can be the same or at the very same location in space. Four points must be specified to create the surface. If you specify three or fewer points an error message is displayed. Four Point Surface Where do I find it Application Modeling Menu Insert Surface Four Point Surface Surface drive24ward mes NX8-HELP SURFACE 2 . Create a surface using four points 1. Choose Insert Surface Four Point Surface to open the Surface by 4 Points dialog box. 2. Select the four surface corner points in the graphics window. You can specify the four points using any of the following methods o Select an existing point in the graphics window. o Select any arbitrary point in the graphics window. o Define the coordinate location of a point using the Point Constructor SLdialog box. o Select a base point and create a point offset from the base point. Note The Snap Point options are useful when you want to specify an existing point on a particular curve or surface. 4. Four specified points 5. Specifying subsequent points displays a polygonal preview on the screen. You can modify any points before finalizing the shape of the surface. 6. Change the location of the points as required. 7. Relocated specified points 8. Click OK or Apply to create the surface. 9. Four Point Surface feature Surface drive24ward mes NX8-HELP SURFACE 3 . Four Point Surface .
