How to do a coil spiral with a outside diameter vs inside

[rcpettit]

I'm doing a solidworks tutorial for fusion and doing great with a few different commands being different.  I'm trying to use the spiral function in coils and need to have it start from an outside diameter vs inside.  I managed to get the desired results but it took time tweaking the inside diameter in tiny increments to get everything to align right.  Is there a way to do this in fusion?

Coil has triangular profile options, inside / outside, select one.  The diameter will adjust accordingly.

Might help...

The spiral function uses the following formula:  Outside radius (center to mid section) = Pitch * Revolutions + (Diameter / 2)

I'm using the flat spiral coil function which doesn't have that option.

Yep, sorry, I didn't read it properly.

Put the formula I posted previously into User Parameters then you can easily control the outside diameter:

Thanks that cleared it up for me.
