Draw Two-Point Perspective

Begin by drawing your horizon line, and placing the front corner
 of your pyramid.(Remember, in two-point perspective, the object
 is turned at an angle, so we begin with a front corner rather than 
a parallel side). For best results, make your vanishing points as 
wide apart as possible. Draw the vanishing lines from the front 
corner to the vanishing points.

Judge by eye how far along the vanishing lines you think the
 back edges of the pyramid ought to begin, and draw a line 
from there to the opposite vanishing point.These lines form
 a diamond shape - where they intersect (cross) is the back
 corner of the base. Then draw the diagonal lines connecting 
the opposite corners as shown. Though they might be nearly 
at right angles,the important thing with these lines is that 
they connect exactly to the corners - they are NOT supposed 
to be parallel or at right angles to the horizon line (though 
they may happen to be so).

Now you need to draw a vertical line to the top of the pyramid. 
Just imagine how high you want it to be, and draw the line that 
far. This line DOES need to be perpendicular (at right angles) 
to the horizon line. Straight up-and-down.

Now you simply draw a line from the top of your vertical line 
to each corner of the base.

If you're drawing a solid pyramid, erase any lines hidden 
by the front two faces - the two biggest triangles - to make
 them look opaque. Erase your vanishing lines. 

other example :

Let's draw a simple box using two-point perspective. 
First, draw a horizon line about one-third down your page. 
Place your vanishing points on the edges of your paper
 using a small dot or line .

Now draw the front corner edge of your box, just a 
simple short line like this, leaving a space below the 
horizon line. Don't put it too close, or you'll end up with 
corners that are tricky to draw.

Now draw a line from each end of the line to both 
vanishing points, like this. Make sure they are straight,
 touch the very end of the line, and finish exactly at the 
vanishing point.

Now we complete the visible sides of the box by 
drawing the corners, shown here with red lines. 
Draw yours likewise, making sure they are nice and 
square, at perfect right angles to the horizon line.
 Not even a hint of a tilt!

This is the tricky part. Drawing the back,hidden sides
 of the box. You need to draw two sets of vanishing lines. 
One set goes from the right-hand corner line (top and 
bottom) to the LEFT VP (VP1). Another set goes from the 
left-hand corner line to the RIGHT VP (VP2). They cross 
over.Make sure you don't try to make any lines meet, 
don't draw lines to any other corners, and don't worry 
about any of the other lines they might pass through. 
Just draw straight from the end of each back line to its 
opposing VP, as in the example

Now you simply have to draw a vertical line from the
 where the lower two vanishing lines cross, to the 
intersection of the upper two lines - the red line in the
 example. Sometimes this can be tricky - the slightest 
of errors can make them a little off center. If this 
happens, either start again making your drawing more 
accurate, or make a 'best fit', keeping your line vertical 
and fitting it between the corners as best you can. 
Don't just join the corners with a tilted line, as that 
will make the box misshapen.

Finish off your two-point perspective box by erasing
 the excess vanishing lines. You can erase the lines of 
the box that would be hidden by they closer sides, or
 leave them visible if it is transparent. In this example, 

the top of the box is open, so you can see part of the back 
corner.

Here are a few more two point perspective examples.
 The steps are just the same as before, but the results
 look a little different depending on where you draw them.
