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

 

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

variable description
L length
A area
V volume
tag custom text tag, saved to object in the drawing
n position of the object within the list
cc incremental value, number of clicks on the 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 applicable functions)

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

 

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

function name description
fx(n)

group function returns an array of results of the previous function

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

x(), y(), z() get a single value out of point (start, end...)
val("any text")  evaluates text (useful 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 the list
L * 100 / sum (Lt) percentage of length in relation to the 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.
  • remember the order of calculations (top to bottom, then left to right)
  • take care, double check results - it may be not what you need, or it may be wrong altogether
