12 | Basics Menus Reference > Create > NURBS Primitives Basics 234 Preserve Position Turn Preserve Position on to preserve overall world-space position by modifying the parented objects' transformation matrix. Create Create > NURBS Primitives Create various geometric primitive shapes using NURBS surfaces or curves. You can create the primitives at the origin or, depending on the primitive options you have set, wherever you click your mouse in the scene view (Interactive Creation). Most of the options are shared between primitive types. When Interactive Creation is turned on and you select a primitive option box, a subset of primitive options appear in a tool window. There are no pivot options in the tool settings. In addition, the Radius/Width/Height/Depth options refer only to single-click creation, not to interactive creation. Note When the Maya workspace is set to High Quality Rendering mode, primitives created using the Interactive Creation option do not appear shaded until the primitive creation steps are complete. Related Links • "Create NURBS primitives" on page 31 of the NURBS Modeling book Create > NURBS Primitives > Interactive Creation You can position and scale primitives as you create them using your mouse, without having to use transformation tools. This option stays on until you turn it off. For more information, see "Create NURBS primitives" on page 31 of the NURBS Modeling book. Create > NURBS Primitives > Exit on Completion This option interacts with Interactive Creation. When Exit on Completion is turned on, you must select a primitive type again in order to create another primitive. When this option is turned off, you can interactively create multiple primitives of the same type, until you select another tool. Create > NURBS Primitives > Type > ˆ Sphere You can create a sphere as the starting point for an assortment of rounded objects, for instance, eyeballs, planets, and human heads.
