Trouble with perspective

Hi there everyone!
I just started reading Andrew Loomis' "Figure drawing for all it's worth", but i'm stucked right at the first pages, when it comes to draw the "projection plane". I'm having trouble drawing those lines (ie the parallel lines that divide the figure in 8 equivalent parts) which are supposed to be equidistant. I don't really know how much distance is decreased by perspective, because i really never worried about that.

Any suggestion? Are there free resources about perspective basics?

Thanks,

Cheers!

Projection plane

Hello

A projection plane is in drawing about like in 3d, it is a Orthographic Plane, mean no depth so there is no perspective. It is as if you could flatten a person down to a single plane, those would be the distances on average.
Even a photo if you took it from waste level of a person facing directly towards you would show perspective distortion, as it is Perspective or 3D space.

If you are having problems with maintaining ratio suggest web search on foreshortening, or perhaps trying Amazon or such sites for books on foreshortening.

Don't know if this is exactly what you mean, but from what you've said I think you're having trouble with distance.

Simple way of sorting it is with use of Orthogonals (receding lines) a horizon and a vanishing point, as below.

The Loomis book "Successful Drawing" covers the fundamentals of perspective.
I have found it at:
