Enla, engineer's Length and Area add-in.

Select lines, polylines, circles or hatches in Autodesk® AutoCAD® and have their length and area values in a list. You can also select solids, and have their volume or centroid.

 

Basic use:

  • select, copy, zoom
  • check values, to find the object you need
  • insert into drawing, as MText, Text or (dynamic) Block
  • export to TXT, CSV, or JSON

And of that will cover most of your daily needs.

 

Advanced use

  • use formula field to evaluate values received from objects with your own custom math expressions
  • insert as combined text, next to each object, or pick location
  • insert (dynamic) blocks, with attributes filled with result of functions
  • override block position to match results of math expression
  • override dynamic block properties such as flip parameters or visibility to match result of expressions

 

To evaluate objects, use standard math expressions in formula tab with optional Enla variables, read directly from selected object:

variable description
L length
A area
V volume
tag custom text tag, saved to object in drawing
n position of object within list
cc incremental value, number of clicks on cumulative button
start start point of line, polyline or similar
end end point
center center point of any object
centroid centroid point, if available

 

or group variables (for aplicable functions)

group variable description
Lt total length of all objects
Ls length of objects selected in list
At total area of all objects
As area of objects selected in list

 

Functions are standard math or logic functions, with introduction of a few special

function name description
fx(n)

group function, returns array of results of previous function

Important: to avoid circular definitions, all functions are calculated from top to bottom for each function in sequence

x(), y(), z() get single value out of point (start, end...)
val("any text")  evaluates text (usefull for custom vars, since they are all text)
text(num,"0#") apply custom formating, using custom strings

 

Examples:

sum(Lt) sum of lengths of all objects
average(As) average area of objects selected in list
L * 100 / sum (Lt) percentage of length in relation to total length
L > average (Lt) 1 or 0, compare how individual L relates to the average length
   

 

Important:

  • if some function accepts two parameters, they must be separated properly with either ; or , sign, depending on your preset windows settings.
  • rembember the order of calculations (top to bottom, then left to right)
  • take care, double check results - it may be not what you need need, or it may be wrong all together

 

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.

    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.
