In this tutorial I am going to show you the basic of Isometric drafting in AutoCAD
Now first of all you need to know what is actually Isometric Drafting ?
Well it is all in 2D,you draw lines,circles and by this way you can draw a 2D and make it look like a 3D,but it is all on one plane and it does not matter if it is TOP,RIGHT or FRONT.
How to turn on Isometric Drafting?
In newer versions of AutoCAD there is an icon at the bottom with ORTHO,POLAR and those features so you are automatically in Iso mode.
I have an older version of AutoCAD and if you have too then right click on GRID icon and choose Settings.
In this window check Isometric snap.It is at deafult on Rectangular snap.
You will notice how your cursor will change.The cursor represents the planes (Top,Right,Left) which you can change by pressing F5.
Now if you choose Line command you will see that it does not go vertical or horizontal like usual but it goes down Y and X axis on plane you are currently on,
Try it and you will see how it changes while you are drawing,but remember it is all on one plane (View),it will look like 3D if you form a nice shape but it id all 2D.
Here is the example,I am on TOP view and this looks like a 3D but it is not ;)
When I choose SE Isometric view you realize that it is just a 2D drawing which would be harder to draw if we did not use Isometric Drafting ;)
I Hope you understood and learned something from this tutorial,if you did not you can always read another tutorial or watch a video,just dont give up ;)
