Cartesian coordinates

In this session, we are going to take a closer look at Model space, otherwise known as our drafting board. Our approach is going to be a little bit different because we are going to look at a Model space from the computer's point of view. Taking this behind the scenes look can be very helpful in teaching us how AutoCAD maintains our line work. Model space is essentially an infinitely large sheet of graph paper. We use this graph paper to construct our geometry and AutoCAD uses this graph paper to maintain our accuracy. AutoCAD maintains our accuracy through the use of baselines.

The first baseline I want to talk about is a major east/west baseline, otherwise known as the X-axis. Now, the X-axis is also a number line and any value to the right of zero is considered positive x, any value to the left of zero is considered negative x. Now, there is another baseline AutoCAD uses. This is a major north/south baseline, it is called the Y-axis. The Y-axis is also a number line. Any value above the X...
