I have a couple of ideas for you. When you project art in CADtools, do you have the “Foreshorten” option checked? If so, the projected art should match AxoTools.
You can also use AxoTools’ Measure tool to get measurements along the different axes, then in the AxoTools Information panel, click the “All” radio button. Now your measurement fields will all be available to select and copy, then paste into your measurement text. It won’t be automatic or dynamic, but in many cases should get you by.
