Ohh, that site pretty much covers it. Or you can also try loading a scene into some 3d program that has isometric view and check it out.

I interested in making isometric drawings, do you guys have any pointers ? |

Isometric, as in non-perspective, "2.5-D"? I don't think you'll find many pointers as it's far from being tricky... all parralel guidelines. |

For abstract references, you may try out POVRay http://www.povray.org/ (a freeware raytracer) with an isometric (I think it's called "orthografic" there) camera. |

You want to do Isometric? or perspective? theres oblique aswell? Isometric (part of the axonometric group!) drawing is based on 3 main angles. 30, 60, 90 using a set square. I did all this stuff in technical graphics at school.
Isometric is pretty limiting though, not too mention un-realistic. Perspective is by far the coolest looking.
I dont know of any websites, but I have a book or two about it, that maybe I could scan a few pages. depends on how much you beg! |

Blithe,
Ian is right. Isometric is usually drawn with 30, 60, 90 degree angles.
It's not intended to be realistic, but it is practical. Before 3D Cad drawing was possible, isometrics were used to draw parts, assemblies, and entire machines. It was practical because if drawn at a specified scale, various drawings could easily be combined and fit together properly.
The procedure for setting up 30, 60, 90 degree angles is pretty easy, but slightly different for each program.
Angles are determined beginning from 0 degrees (a horizontal line) and rotating counterclockwise so that 90 degrees is a vertical line. If you want an angle drawn below 0 degrees, moving clockwise, type for instance -30.
There are no vanishing points in isometric drawings as a box turned to 3/4 view is a wide at the back as it is at the front.. all lines going in the same direction are parallel, in other words.
The principles are quite simple and easy to learn. The thing most beginners get screwed up is the ellipses. They need to be drawn within either an imaginary or guideline box turned to represent the appropriate plane (or flat side of the object).
An ellipse is simply a circle that's been rotated in one direction or the other and depending on the degree of the rotation, the circle (or ellipse) will become more or less narrow. For instance, a 30 degree ellipse is more narrow than a 60 degree ellipse.

I see what you guys mean now, after a few hours in corelDraw the whole think just out of hand, I remember doing isometirc drawings in grade 9 or 10 in autocad (hate the program), stuff like screws, hindges and stuff within those boarders.
Anyways, I just wanted to give it a shot and see what's it all about. Thanks for the input guys. |
