Patterns
Patterns are arrays of objects copied in specific arrangements, and controlled parametrically. Patterns of solid objects act as solid and they and/or their elements can be manipulated by 3D tools, like Bend, and patterns can be Booleaned with other 3D objects. There are six pattern tools: Array, On curve, Radial, Spherical, Cylindrical, Pattern on Polyline.
Associative Arrays
You can use the pattern tools to create 2D and 3D arrays of 2D objects, 3D objects and blocks. Update the arrays in arrangement, number, columns, levels, and rows.
