Lattices display N-dimensional objects as a series of 2-D cross-sections. Lattices have six axes that determine the location and size of each cross-section and may be rotated, or their orientation may be reversed. The perspective axis (x-y) determines the rotation of the lattice and the three orthogonal axes (x-y, y-z, x-z) determine the size of the cross-section. In AutoCAD, the user must specify the characteristics of the lattice. AutoCAD has four basic types of lattices. These are line, solid, curved and surface lattices. An Inventor drawing object can contain more than one lattice. If more than one lattice is used within an object, they can be displayed using different rotation or size attributes. I create different lattices for different objects. For example, I may have a 3-D object containing both a line and curved lattice and a 2-D object containing a surface lattice. For example, to create a solids-like drawing, I can use a smooth lattice. This is accomplished by setting the Tolerance level of the lattice. A Tolerance level of 0.01 inches produces a smooth surface. A Tolerance level of.005 inches produces a slightly jagged surface. Lattices have a number of attributes that can be set or read. For example, the End and Start positions of the line lattice are used as the center of the 3-D region. If the top and bottom of the 3-D region are also specified, then the depth of the lattice is determined. Other attributes of the lattice can be set or read: Bounding Box, Boundary, Edge type, Height, Sides, Width, and Miter Limit.
. (Curved) - Curved lattice curve. (Surface) - Surface lattice surface. (Solid) - Solid lattice solids. The selection of lattice type can be set using the Object Attributes panel in the Mesh panel. For more information on the Mesh panel, see Bounding Box, Curves. (0.01-0.001). Optionally, I can set the smoothness, such as by entering a value
