Hi ,

One of the problems that I've to constantly dealt with when drawing in perspective is foreshortening an object that is tilted at a certain angle. Can anyone provide me something like a formula or a tutorial on the net on how to deal with foreshortening precisely and not just by mere estimating (This is how I do it and it often ends up really crappy!). THANKS IN ADVANCE!!

If you are drawing from life or reference, just force yourself to look beyond the subject matter and just draw the shapes. If it's a reference image, turn it upside down and you'll be able to draw just the shapes much more easily. If you are working from your mind... try blocking in a simple perspective box (bounding box) to grasp the overall shape and foreshortening. Hopefully you can use this as a reference kind of frame to help you continue. I have done this once or twice and it seems to work relatively well for me, although sometimes it doesn't.

You have to 'draw through' your drawings.

This site can guide you to the right direction

The tutorials there would help.

Apparently 'draw through' principle is so important that the guy [scott neville] named his website after it.
