Instead of having to make sure you add your parameters beforehand (which works if you already know what they will be as in the case of this geneva wheel, but very often you wont know ahead of time</P></BLOCKQUOTE><P>&nbsp;</P><P>I agree. You can always dimension things first, then go into the list of user parameters and name them but it would be way better if you could just name them on the fly. You should add that as a feature request in the forums if it's not already there.</P><P>&nbsp;</P><P>Rob</P> Sat, 15 Aug 2015 18:52:51 GMT robduarte 2015-08-15T18:52:51Z
