Update area information automatically





You can now find higher, more general functionality in our new application - LiveLabel

AreaUtil reactor

AreaUtil The AreaUtil utility (for AutoCAD and AutoCAD LT) transfers information about the area of the selected closed polyline or polygon into the selected block attribute. A live link is created in your drawing and then the attribute value is updated automatically or on demand at a change of the polyline.

You can link any user block with attributes. Current area (acreage) is updated automatically at any change of the border polyline. Can be used eg. for simple and precise display of true area of parcels, rooms...


Installation

Unpack the distribution archive to any folder on your hard disk. Load the application into AutoCAD by the ARX or APPLOAD commands.
If you want to load the application automatically when launching AutoCAD, add the areautil.arx reference to your acad.rx file - located usually in AutoCAD Support folder.

Example of the acad.rx file

D:\Utility\Areautil\areautil.arx


Commands

Application contains only a single command - AREAUTIL. This command contains these options:
Create creates a new link between a polyline and selected block attribute.
Options displays dialog for option settings. If you are using always the same attribute name, you can check the Run in quiet mode options and enable the "quiet mode" with a default attribute name. Command then doesn't show the Select attribute dialog and uses instead the default attribute name set in the Default attribute box.
Update updates all drawing entities with links created.


Example

Create link

  • Open the tutorial1.dwg drawing
  • Use the ARX command to load areautil.arx (or areautil_demo.arx)
  • On the command line, enter AREAUTIL command
  • Enter the Create option
  • Select the red polyline
  • Select the rectangle inside the red polyline
  • In the Select attribute name dialog select the AREA attribute
  • Close the dialog by OK button

Automatic update

  • On the command line, enter AREAUTIL command
  • Enter the Options option
  • In the Options dialog, check the Allow automatic update
  • Close the dialog by OK button
  • Use grips to change shape of the polyline
  • New value of the area is displayed automatically in the attribute

Manual update

  • On the command line, enter AREAUTIL command
  • Enter the Options option
  • In the Options dialog, uncheck the Allow automatic update
  • Close the dialog by OK button
  • Use grips to change shape of the polyline
  • On the command line, enter AREAUTIL command

  • New value of the area is displayed in linked attributes

You can even create several links from one border polyline to more blocks - eg. one descriptive in the center of an area and another in the legend. You can use the attached AREABLK.DWG as an example for the description block.
