Enla, engineer's Length and Area add-in, is designed to make reading and manipulation with length and area easier.

Select lines, polylines, circles or hatches in Autodesk® AutoCAD® and have their length and area values in a list. 


From this point you can:

  • select all or some items in list to see cumulative values
  • click on "copy" icon to copy selected values to clipboard
  • click on "zoomto" icon to zoom to that object in AutoCAD
  • pin selected items to track object no matter of current AutoCAD selection, and watch values change as you change object's dimensions
  • add a tag on selected items to make easy manipulation once values are pasted to, for example, Excel®
  • choose round and scale options and the way values are shown (system locale or different)
  • insert values in drawing as a text or field (where applicable), next to its originating object
  • insert values as table
  • insert as block and populate attributes or dynamic properties with values
  • evaluate custom math expressions 


To evaluate objects, use standard math expressions in formula tab with optional Enla variables

  • L = length of object (when inserting as field, not all objects can use it)
  • A = area of object (if object has it)
  • n = position of object in list
  • cc = incremental value, number of clicks on cumulative button
  • tag = custom text tag, saved to object in drawing
  • Lt = total length of all objects in list
  • At = total area of all objects in list
  • Ls = cumulative length of selected in list
  • As = cumulative area of selected in list 



L * 100 / sum (Lt) = percentage of length in relation to total length

average (As) = average area of objects selected in list

L > average (Lt) = 1 or 0, compare how individual L relates to the average length



This add-in is the free version of Enla. You may use this add-in for a non-commercial purpose, or you should consider buying Enla.

In terms of software features, the only difference between commercial and student version is just the title.

About This Version

Version 3.2.0, 3/26/2018
major bug fix: 1) if hatch is selected, then without deselection modified only once with mouse - then area value is not updated in list 2) if option is on to include AutoCAD parametric values in Enla formula, and also there are items in list with "pin" on, then when switching layout, CAD will crash changes: removed some options that were confusing or less intuitive 3) Added latest support

    This add-on is very useful. I have looked up so many lisp, and-ons and those are not good as this one. Thank you so much about it. I just want to ask you a question about versions. I'm using student version right now. Is there any limitation student version according to full version.

    Единственное, что хотелось бы добавить, чтоб можно было удалять лишний выбранный объект; а так же при отмене выделения объектов, значения площадей сохранялись в приложении (к примеру, если что-то требуется изменить на чертеже в процессе выбора объектов)?!

    Thank you for your interest in ENLA. To my best undestanding of your question, I will say that ENLA will always follow active AutoCAD window selection. So, to deselect one object in a group of selected objects, click on the desired object in the main AutoCAD window (model space for example), while holding SHIFT key. Object will be removed from AutoCAD selection, and because of that - it will also disapear from ENLA window, unless it has "pin". If it has "pin", it will stay in list until you delete that object in the drawing itself, or until you remove that "pin". So, to be able to modify, select/deselect object and that this specific object is always shown in list - use "pin" on that object. Also, if you have more questions, you are welcome to use support e-mail. Thank you.
