This invention relates in general to three-dimensional (3D) computer-aided design (CAD) systems, and more particularly, to a method, apparatus and article of manufacture for generating a (U,V) texture mapped surface. To overcome the limitations in existing systems the present invention discloses a method, apparatus and article of manufacture for (U,V) texture mapping of object surfaces in a 3D graphics system in such a way that the size of the texture is preserved, and the texture wraps around curved surfaces, even when the surface is scaled. One or more triangles are selected from an arbitrary mesh of triangles. A plane normal and a (U,V) origin of the plane normal is determined for each selected triangle. The surface of the selected triangle is texture mapped using the plane normal and the (U,V) origin.
