q3d 指导书 Overview of Draw Primitives In solid modeling, the basic element or object is often called a primitive. Examples of primitives are boxes, cylinders, rectangles, circles, etc. There are two types of primitives: 3D primitives or solids, and 2D primitives or surfaces. By placing a collection of primitives in the correct location and of the correct size we can create a represent complex structural objects. To create complex objects, primitives can be used as “tools” to cut holes, carve away, or join. The operations that are performed with these “tools” are often referred to as Boolean operations. 2D primitives can be swept to create arbitrarily shaped solid primitives 2D Draw Objects The following 2D Draw objects are available: Rectangle, Circle, Line, Point, Spline, Ellipse, Regular Polygon 3D Draw Objects The following 3D Draw objects are available: Box, Cylinder, Sphere, Torus, Helix, Bond Wire, Cone, Regular Polyhedron True Surfaces Circles, Cylinders, Spheres, etc are represented as true surfaces. In versions prior to release 6, these primitives would be represented as faceted objects. If you wish to use the faceted primitives (Cylinders or Circles), select the Regular Polyhedron or Regular Polygon. To control the mesh generation of true surfaces objects, see the section on Mesh Contro
