I am trying to create a field that picks a certain numeric value from preexisting text. For example, shown in the picture is "COND-A: #.# in^2". The "#.#" is eventually filled in with a number referring to area, I want to be able to select just that number once filled in. Right now I have my field set up with an object selection and that selects the whole text, I cannot figure out how to select just that numeric value. I know there is a measurement property under object selection but that does me no good. Likewise, I know there is a diesel expression for selecting specific text from one of my layout tabs:
$(substr,$(getvar,ctab),1,4)
This gives me the first 4 letters from my layout tab name rather than selecting the whole layout tab name. If there is a diesel expression for this, there must be one or some other way to do this for that area number in this example. This is very difficult to explain ove text so if there are is anything unlcear please let me know.
