Expression Builder and Zoom Formula Field

[Nurlan-A.]

Problem:  Sometimes, writing a formula in the family editor can be daunting. One have to use Notepad to build a formula, copy and paste parameter names, open a formula guide for reference, insert a written formula into a field and get a syntax error, look for error, because Revit does not specify where the error is. Also additional steps are needed to overview an excising formula since a small single-line field does not allow one to see the entire formula.

Idea: Please introduce the "Expression Builder" which will allow users: zoom-in the formula field with a hotkey, insert parameter names, add build-in functions and operations and highlight syntax errors.

The idea was "inspired" by a similar function in the MS Access.
