Drawing in three dimensions

Creating Surfaces

Creating boxes
  1. You can create rectangular boxes, or cubes. A box consists of six rectangular surface planes. The base of the box is always parallel with the xy plane of the current UCS. You position the box by specifying either a corner or the center of the box. You determine the size of the box by either specifying a second corner and the height; defining the box to be a cube and then providing its length; or specifying the length, width, and height.
To create a box as a three-dimensional surface
  1. Do one of the following:
  2. Choose Draw > Surfaces > 3D Surface and than type Box.
  3. On the Surfaces toolbar, click the Box tool (
  4. ).
  • Type ai_box and then press Enter.
  • Specify the first corner of the base.
  • Specify the lenght of side of box.
  • Specify the width of box.
  • Specify the height.

  •  

    First corner of the base ( A ), the opposite corner of the base ( B ), and the height ( C ).

Creating wedges
  1. You can create three-dimensional wedges consisting of five surface planes. The base of the wedge is always parallel with the xy plane of the current UCS with the sloped face opposite the first corner. The height is always parallel with the z-axis. You position the wedge by specifying either a corner or the center of the wedge. You determine the size of the wedge by either specifying a second corner and the height; defining the wedge based on a cube having a given length; or specifying the length, width, and height.

Creating pyramids
  1. You can create tetrahedrons (three-sided pyramids) or four-sided pyramids. The sides of the resulting pyramid can meet at a point (the apex) or can form a three- or four-edged top. The sides of a four-sided pyramid can also meet along a ridge defined by two points. The base of the pyramid is always parallel with the xy plane of the current UCS. You position the pyramid by specifying a corner of the base. You determine the size of the pyramid by specifying the base points and either the apex, the corners of the top surface, or the endpoints of the ridge.
