Type AOL/POL/APL or select from Autodesk® AutoCAD® Ribbon > Add-ins > Area Object Link panel to start one of these commands. The first time AOL or Area Object Link / POL or Perimeter Object Link / APL or Area Perimeter Link is executed, a graphic user interface (GUI) will appear displaying the current AOL/POL/APL Commands & Options:

AOL/POL/APL Commands:
- Link already drawn Circles, Ellipses, Hatches, Plines, or Regions' Area/Perimeter value using Fields to an already placed Attribute, MText, or Text.
- Insert a pre-built AOL/POL/APL Block with Attributes & then link using Fields to already drawn Circles, Ellipses, Hatches, Plines, or Regions' rea/Perimeter.
- Draw using the Pline command a closed boundary shape and then insert the AOL/POL/APL Block linking the Attribute to the Area/Perimeter value.
- Select already drawn supported objects like closed Plines and then automatically insert the AOL/POL/APL Block at the center of each selected shape linking the Attributes to the area/Perimeter value.
- Show Circles, Ellipses, Hatches, Plines, or Regions highlighted & shaded with Areas/Perimeters linked using Fields to selected Attribute, MText, or Text.
- Update Fields in Attributes, MText, Text & Block Attributes with Area/Perimeter value to match with the current AOL/POL/APL Option settings.

AOL/POL/APL Options:
- Choose Imperial or Metric as your drawing unit standard.
- Select an Insertion Scale factor to bring in the pre-built AOL/POL/APL Block Attribute.
- Use the horizontal slide bar or enter a specific Rotation angle to insert the pre-built AOL/POL/APL Block Attribute.
- The Area/Perimeter can be measured using a number of standard conversion Factors in both Imperial or Metric systems including an option to enter a Custom Factor.
- Select the option to include a prefix/Suffix to the Area/Perimeter value.
- Set a decimal Precision using a Dot or Comma or Round the calculated Area/Perimeter value Up or Down.
After the first time, the following occurrences of running AOL/POL/APL will automatically take on the previously selected Command & Option settings bypassing the GUI.

Type AOLSET/POLSET/APLSET or select from AutoCAD's Ribbon > Add-ins > Area Object Link panel to bring the Command & Option settings GUI up again to make additional changes.

TypeAOT or select from AutoCAD's Ribbon > Add-ins > Area Object Link panel to start the command. The first time AOT or Area Object Table is executed, a graphic user interface (GUI) will appear to generate a Summary Table displaying the following Options:
- Select one of the following to generate the Summary Table. AOL-Label [AOL Module]; 2. POL-Label [POL Module]; 3. APL-Label [APL Module]
- Customize the Summary’s: 1. Table Heading; 2. Column Headings
- Create an Excel file
- Total up the values
After the first time, the following occurrences of running AOT will automatically take on the previously selected Options bypassing the GUI.

Type AOTSET or select from AutoCAD's Ribbon > Add-ins > Area Object Link panel to bring the Options GUI up again to make additional changes.

Type ACL or select from AutoCAD's Ribbon > Add-ins > Area Object Link panel to start the command. The ACL or Attribute Change Layer command changes selected Blocks along with the Attributes’ layer to a selected target object layer.

Type AOLINF or select from AutoCAD's Ribbon > Add-ins > Area Object Link panel to start the command. The AOLINF or Attribute Object Link Information command brings up a graphic user interface (GUI) offering the following: 1.

1.     The end user should leave the Autodesk® AutoCAD® Fieldeval system variable to 31 so that the Area/Perimeter saved as a Field in the Block Attribute or Text will automatically update.

2.     As stated in AutoCAD's help file on Fieldeval, one of the following commands will need to be executed for the Area/Perimeter value to automatically update: Open, Save, Plot, eTransmit, and Regen.

3.     Table totals are dependent on the selected precision of the resultant Area/Perimeter values. The final calculations vary depending on number of decimal places selected.
