Definition

In our definition,

• Member is the basic structure part with some basic shapes, e.g. rectangle, circle, or I-shape. (TBD)
• Component can be simply divided into four major types -- superstructure, substructure, deck and surface feature. Each of them can be assembled by the basic members. (TBD)
• Bridge is the assemble of different components, which should be in the form of real bridge. (TBD)

Package

Member

In member.py, the superclass Member is defined as an abstract class that represents the common attributes and methods of each concrete "member".

member's attributes

We use cfg to define the name and shape of each different shape. The cfg file should be a dictionary with the following format.

cfg = {
    'name': xxx,
    'shape': {
        'detail1': ,
        'detail2': ,
        ...
    }
}

As an example, the configuration for rectangle is

rectangle_cfg = {
    'name': rectangle,
    'shape': {
        'Flange length': 2,
        'Web length': 1,
    }
}

The other attributes are given in the table.

Attribute	Data Type	Description
name	str	The name of the shape.
shape	dict	A dictionary that includes all the parameters of the shape.
yz	2d numpy.ndarray	The coordination of one cross-section for the shape in the yz-plane.
faces		The collection of the faces of the object.
vertices		The collection of the vertices of the object.
cs_num		The number of cross-sections.
translation		The translation for the cross-sections.
rotation		The rotation for the cross-sections.
npts	int	The number of points in one cross-section.
obj	bpy.types.Object	The corresponding blender object with the specific shape.

member's methods

Methods	Usage
showCrossSection()	An helper method returns the cross-sectional view of the object
createObj(name)	Create a blender object with the input name.
