how to automatically calculate angle parametric design

[Anonymous]

I have a question, I am working on a parametric design.

I need to draw a coil that is at a angle, but the angle is not always the same.

for example,

i have a body with these dimensions:

Top:80

Bottom:70

height:90

I need to draw a coil at a angle, that angle needs to be the same as the side of the cylinder.

the angle in this example needs to be: 3.17983 deg

but it has to calculate it automatically, how do i do this?

Create a parameter using this formula atan(( CylinderTop - CylinderBottom ) / 2 / CylinderLength) 

Make sure the unit type is Degrees.

Thanks! it works, but i have one question, the value is 3,2deg but the exact value is 3.17983 deg is it possible to get a more exact value

Go to your preferences and under Angular Precision change to more places on the Unit and Value page. Not sure but I think the system uses more places than's displayed.
