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.

  • add current precision to value formatting
    tung nguyen | enero 25, 2024 Descarga verificada (¿Qué es esto?)

    this plugins work perfectly but could you add current precision to value formatting because sometimes i need to change all the attribute (i created ) value precisions to more or less zeros

    Paul Li (Editor) | enero 26, 2024

    I'm glad the AOL app is working out for you. You should be able to select a different precision under the "Precision" section on the lower left hand corner of the app window before "Inserting" the AOL Block Attribute. After "Inserting" the AOL Block Attributes if they all have the same formatting (scale & suffix) and you want to change their precision format, you can select under the "Area Object Commands" section on the top right hand corner the "Update" radio button then on the drop down list choose "All AOL Blks". Then select a different "Precision" and after clicking "OK", all the previously inserted AOL Blocks precision values will be updated to match.

    sorry for misunderstanding. I mean i just need the area field follow the current precision or current units so i can quickly change the number of the zeros by change the units setup

    Paul Li (Editor) | marzo 26, 2024

    Unfortunately, the app currently does not have an option to select precision/unit values to match with the current precision/units value. Perhaps this option is something that can be added in a future release. Thanks again for your interest in the AOL app.

    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 (Editor) | julio 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 (Editor) | septiembre 03, 2021

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

  • more personalization
    harinezumi 針鼠 | enero 22, 2017 Descarga verificada (¿Qué es esto?)

    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

    Daniel Moraes | marzo 28, 2018

    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.

    harinezumi 針鼠 | abril 04, 2018

    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 (Editor) | junio 10, 2021

    harinezumi, this feature has been added in version 4.0.0. Please download the latest and give it a try.
