Hi,

Fabrice, you have a problem with the definition of the path b: this path include q and b. To see this, replace your lines with :

           draw q anglestriped (1,45,2) withcolor cyan;
           draw b anglestriped (1,45,2) withcolor red;

And you will see that the path b is drawn twice : once in red, once in cyan. So if you change your instructions to :

           draw q anglestriped (1,45,2) withcolor cyan;
           draw r anglestriped (1,45,2) withcolor cyan;

This will correct the problem, because each path is now drawn only once. 

Fabrice.
