M.L.T.E. (pronounced "multi") is program extension that is used inside Autodesk® Revit. It is a multiline text editor that can be used for editing the parameters of anything inside Revit but in a multi-line view instead of the single line that Revit's Properties Palette gives you. In addition to editing the values of parameters M.L.T.E. can also edit the formulas when used inside the Revit Family Editor. It even has syntax highlighting and auto-formatting to make complex nested if statements easier to follow and debug.
