The goal of this exercise is to further the concepts developed in Exercise 02 to create a 3-Dimensional parametric shape through geometric controlling operations. The script created will generate a 3D representation of a user-defined auditorium space.

Given the limitations posed by the simple array toolset explored in Exercise 01, the objective of this exercise is to create a parametric script that use variables and invokes functions to have more meaningful control on how shapes and objects are drawn, which in this case, is 2-Dimensional section representation of a tiered auditorium space. The goal of exploring these concepts is to further understand how the program can evolve into one that takes of advantage of control structures in the multi-dimension.

The objective of this exercise is to create a Python Batch program that generates a simple array of a 3D object.

#this links python to rhino
import rhinoscriptsyntax as rs

#this prompts user to select desired object to array
rs.SelectObjects

#Array = Number in X Direction _ Number in Y Direction _ Number in Z Direction _ Spacing in X _ Spacing in Y Direction _ Enter
rs.Command ("selall")
rs.Command ("Array 5 5 1 12 14 enter")
