I am wondering if anyone knows a way to accomplish a code what Updates with a Dimension. Simple Example: Say I have a Dimension that reads 10'-0" And I have a object above it Is there a way to Have like a string of code do..."10'-0" + 6" / 2....And so on Then have the reading above it Adjust when ever the Dimension Increases or Decreases? The reason why is we have a code that Gets the Length of a Dimension and passes that number through a Code and Writes it to a Block attribute. Is there a way to have this Automatically Update when the Dimension Changes? Any help would be much appreciated!!! Thanks Mark
