But I changed my Nokia E71 phone (amazing piece of engineering, by the way) for a Samsung Galaxy S. My wife says it's a wannabe iPhone... I say under the bonnet it has a very different beast: the android OS.

I got tired of waiting for the android 2.2 version to reach the market... and all manufacturers are promising great new features in the phones "about to be released".

This time it's one of the short easy-come easy-go projects, start to end in 2 hours.

Based on the capability of the new adaptive components I quickly built a family that would drive the height from the coordinates x y (Reporting Parameters) of the Adaptive Point (using in principle the technique described by Zach Kron here), but using the complicated formulas in the report...


The result is a Revit fam…
