LESSON 2 - PRIMITIVES
This video will outline what to expect as you progress through this Chapter. Primitives are the most
basic and easy to use tools in the program and a great place to start designing. Within these tools
you will be able to insert full objects into the 3D space and change the size within the options box
at the bottom of the screen. Objects can be placed on the grid or on top of another object.
The following video outlines every object within this toolset and the geometry involved with each.
OVERVIEW
7
BOX
The box command is the most basic 3D object you will work with. It has six sides, just like
a traditional set of dice you play with
Length of the Box.
Width of the Box.
Height of the Box.
Insertion Point of the box.
8
SPHERE
The Sphere tool creates an object similar to a basketball or marble. A sphere has one length
from the centre to every other point on the surface and therefore is smooth and has no corners.
The radius of the sphere.
The insertion point of the Sphere.
9
CYLINDER
The Cylinder is just like the shape of a pop can, you have two measurements to work with.
First you have a radius that makes it thinner or fatter and second you have a height which makes
it taller or shorter.
The radius of the Cylinder.
The height of the Cylinder.
insertion point of the cylinder.
10
CONE
The cone tool is very similar to the cylinder tool.It needs both a radius and a height before it can
be put in the drawing. Some examples of cones that are found in the world include: ice cream
cones and orange traffic cones.
The Radius for the base of the Cone.
The Height of the Cone.
The Insertion Point the Cone.
11
TORUS
The cone tool is very similar to the cylinder tool.It needs both a radius and a height before it can
be put in the drawing. Some examples of cones that are found in the world include: ice cream
cones and orange traffic cones.
The Major Radius of the Torus.
The Minor Radius of the Torus.
The Insertion Point of the Torus.
12
2D OBJECTS:
RECTANGLE
The Rectangle Tool can draw Rectangles or square shapes. The size and shape is determined by
the Length and the Width.
The Length of the Rectangle.
The Width of the Rectangle.
The Insertion Point of the Rectangle.
13
CIRCLE
The Circle tool will draw a perfectly round circle. The length of the radius will determine the
length from the centre of the circle to the edge.
The Radius of the Circle.
The Insertion Point of the Circle.
14
ELLIPSE
To draw an Ellipse, start by clicking on the plane or surface you want it drawn on. Then, enter
the measurements you want for the Major and Minor radius.
The Major Axis of the Ellipse.
The Minor Axis of the Ellipse.
The Insertion Point of the Ellipse.
15
POLYGON
The Polygon tool draws shapes with multiple sides that are the same length. The radius will
outline the distance from the centre to the outside points of your polygon. Choose the number of
sides of your polygon, This is a great way to make a Triangle too.
The Radius of your Polygon. From the Centre to the outer points.
The number of Sides of the Polygon.
The Insertion Point of your Polygon.
16
The Polygon tool allows you to create many different shapes. Essentially,
a polygon is a 2D shape with as many sides as you want, as long as the
sides are straight. For example, a stop sign is an octagon, meaning it has 8
straight sides.
You can make many different types of shapes by changing the number
of sides on your Polygon.
