assonometry with tipping

[fenicotteroblu]

I have to draw a 'parallel solo of a parallelepipedo using the method of tipping.
I have understood more or less how to represent the assonometrics but when using the tipping it is difficult to me.
When do I turn the triangle as it should be? and the measures of the parallelepiped how do I find them?

here is an example of axometry quarry with the method of tipping.

It's not exactly what my teacher wants, but thank you anyway.

then you should post a drawing, a sketch also made by hand, that gives the idea of what the professor wants.
For example, it would suffice the view in the plant, something that gives the idea of how the parallelepiped is placed in space 3d so that you can understand how to start doing the asonometry.
