Length and area. Select, calculate, increment, zoom, copy to clipboard, insert next to object as text, field, table, (dynamic) block, or simply export to text, CSV, JSON or XML file.

General Usage Instructions

Start app by typing "Enla" or clicking on icon, and the palette will show up. Select lines, polylines, circles, or hatches in Autodesk® AutoCAD®, and the list will populate. Select lines, polylines, circles or hatches in AutoCAD and have their length and area values in a list.

Use variables L, A, n, cc and standard math functions, including some range functions like median(), standard deviation stdev(), or sum() with symbols Lt, Ls, At, As. You can also use if(condition,true,false), or and() and or(). When using range functions, function arguments are separated with comma or semicolon(depending on your country).

It's fun to play, but never forget that some functions may have different syntax in formula (or Excel) then in AutoCAD, such as:

  • angle is in radians in Enla (like Excel), but when inserted as field, AutoCAD may expect degrees
  • for decimal numbers, the decimal sign (point or comma) in set in the settings tab, and default sign is used for selected language
  • use expressions with caution and common sense



Ribbon/Toolbar Icon Command Command Description


Main command, shows palette with list and options.


The installer that ran when you downloaded this plug-in from Autodesk App store has already installed the plug-in. You may need to restart the Autodesk product to activate the plug-in.

Additional Information

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.

Known Issues

Notice: use common sense!

Values returned need further inspection. Just because some value is shown doesn't mean it is also a useful value. Objects may overlap, self-intersect, be non-closed and a source of otherwise dubious numbers.

Version History

Version Number Version Description


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


insert as block. Is now possible to use AutoCAD parametric variables.


Added 2017 support


minor update with new, aditional types of objects available to evaluate:

  • region
  • surface


new options allow you to:

  • type custom formula to evaluate length and area objects using standard math functions and expressions, with the place to test results (calculator)
  • store multiple math evaluations and set one to be active
  • insert text values can now be rotated for best view in different UCS
  • insert text positions can now also be central (to imaginary bounding box) and centroid (if applicable)
  • indication of potentially non-usable polylines is now both in color and in sign
  • cleaner way to turn on or off displaying of either length, area, math functions or tags


new options allow you to:

  • insert values (length and area) as text, next to its originating object
  • indicate some polylines that may have non-usable values (self-overlapping, self-intersecting, hard to close...)



new options allow you to:

  • choose default actions when you double click on item in list (zoom or copy)
  • control the way selection works when picking items in list
  • tailor the way round and sum works
  • ability to control units style and export for different localizations


  • Live properties - select object in drawing and as you move its grips, length and area values in list will change.
  • Zoom to - selected items in list, and click to zoom to extents, or double click on item in list.
