Log Post Diameter Parameters

[dholmes8]

Creating a simple log post that needs to be able to change diameter and height.  The height will flex as needed.  But when I adjust the diameter the reference planes will adjust correctly, but the log diameter does not follow.  How do I lock that extruded circle to the reference plane?  Family file is attached.

Thanks!  Do you mind sharing the trick?  Comparing your BB2 to the original and I do not see what was changed in the set up...other than yours actually works!

One is controlled via a radius dimension (placed in Sketch Mode) associated to a parameter that is driven by formula =Diameter/2. 

The other is 2 halves of a circle constrained to x and y Ref. Planes.  Enter Sketch Mode to see.

You can simply place a diameter dimension to the sketch.
