====== Template CATPart for Assignment 3 ======

~~DISCUSSION~~
We’ve prepared a sample CATPart to help with the set-up for the bus stop component model.  It’s in the materials section of the wiki under assignment 3:\\
http://php.twofourfour.org/dokuwiki/stanford/materials

All of the ‘driver’ parameters and their associated ranges have been added to the part.  Note the following changes to the ranges:\\
Sidewalk_Width: 8-14ft (to give you a little more room to work with)\\
Person_Age: 5-100 years\\
Waiting_Time: 0-90min\\
Sun_Direction (Solar_Elevation): 75.5deg (highest point during summer equinox) – 28.8deg (highest point during winter equinox)\\

Some additional parameters have been added to define the curb (Under ‘Site_Config’ in the parameter tree):\\
Site_slope: The slope of the street measured from the horizontal plane (0-20deg)\\
Site_orientation: The orientation of the street with respect to North\\ 
Curb_Y_length: The length of the curb which can be devoted to the bus stop (30-80ft)\\ 
Curb_radiusOfCurvature: The curve of the street (infinite to 50 ft)\\

Also, there are a couple of geometric sets in there for reference:\\
1.	‘global_axes’: 3 lines (length 1ft) corresponding to north, east and vertical.  These directions will remain the same regardless of the street (curb) orientation.\\
2.	‘site’: Contains a geometric set, some lines and sketches –\\
2.1	‘site axes’: 3 lines defining the x,y and z axes for a particular street/curb configuration.\\
2.2	‘curb’: sketch defining the street curb (grey arc)\\
2.3	‘site_boundary’: sketch defining the sidewalk (green arc), which is the side and rear boundary of your site\\ 
2.4	‘wind direction’: (blue) line corresponding to the direction of the wind measured from the site X axis\\
2.5	‘view direction’:  (purple) line corresponding to the direction of the view measured from the site X axis\\
2.6	‘sun direction’: (yellow) line corresponding to the solar elevation measured from the horizon\\
