The UV grid acts as a guide in patterning the surface. Manipulating the divided surface also manipulates the parametrically dependant patterns and components. Certain parameters of the divided surface can be edited in the drawing area of the conceptual design environment.
Since surfaces are not necessarily planar, the UVW coordinate system is used to plot location. This maps a grid adjusting for the contours of a non-planar surface or form. UV grids, as used in the conceptual design environment, are comparable to XY grids.
