Area Object Link (AOL)

Area Object Link (AOL)



Area Object Link (AOL) is an add-in app coded entirely using AutoLISP®/Visual LISP® offering 100% Autodesk® AutoCAD® compatibility. AOL provides a graphic user interface (GUI) adding 4 new & powerful commands to facilitate the implementation of Fields but bypassing the complexity of the Fields GUI.


AOL Area Object Commands:

  1. Link - simplifies steps needed to Link the Area value of already drawn Circles, Ellipses, Hatches, Plines or Regions as Fields to already placed Attribute, MText or Text.
  2. Insert - proceeds to insert a pre-built AOL Block and then links using Fields the Attributes to already drawn Circles, Ellipses, Hatches, Plines or Regions' Area value.
  3. Show - allows the user to select an Attribute, MText or Text with Fields to show the object(s) highlighted & shaded that have linked Area values.
  4. Update - gives the user the option to select pre-built AOL Block, Attribute, MText and Text objects with Fields that contain linked Area values updating them to match the current AOL Option settings.


AOL Option Settings:

  • Both Imperial (1 unit = 1 Foot or Inch) & Metric (1 unit = 1 Meter, Decimeter, Centimeter or Millimeter) drawing units are supported.
  • The Area value can be measured both in Imperial units (Square Feet, Square Inch, Square Yard, Square Mile or Acre) & in Metric units (Square Meter, Square Centimeter, Square Millimeter, Hectare or Square Kilometer). You can also enter a custom area measuring Factor.
  • You can select various Insertion Scale Factors, Rotation Angles, choose to add a Suffix to the Area's value such as SF or SM and show the Area value formatted to a given decimal Precision using Dot or Comma or Rounded Up or Down.

    Great! It took me a lot of work to do this manually. you can add option about decimal separator. in my country use comma instead of period. thanks

    Paul Li (Разработчик) | июля 22, 2021

    Glad this saved you lots of work....I may consider adding the comma option as the decimal separator in future versions.

    Paul Li (Разработчик) | сентября 03, 2021

    Version 4.1.0 released on September 3, 2021 added the comma option as a decimal separator.

    I like most the link function (I use mtexts). But I need more personalization: I work in cm and I need area in sqm, and this can't be done. Thank you anyway

    I had de same issue. In the lisp file, find de line %<\AcObjProp.16.2 Object(%<\_ObjId 681176416>%).Area \f "%lu2%pr2%ct8[1.000000000000000E-006]%th44">% e change de value 1.000000000000000E-006 to 0.0001. This changes de value of the Conversion Factor inside Field Additional Format to 0.0001. It Works.

    Dear Daniel, thank you for yout work-around but I also use drawings in m and mm, so changing the lisp is not a solution for me

    Paul Li (Разработчик) | июня 10, 2021
