Adding AreaNotes

Use the AreaNote command to highlight and annotate areas in a drawing.

You can specify areas by clicking a point within a closed boundary or by specifying points that comprise an area to measure.

Along with the calculated area, the command applies solid hatches and fills in bounded areas with a specified color.

Filled areas help to differentiate areas. For example, within a floor plan of a building, you can highlight each room with a different color.

For calculating areas, you can also use the GetArea command.

The command calculates the following:

• Area, Perimeter, Length or Circumference of an entity
• Areas defined by specifying points

The command displays a dialog box where you can specify drawing units, solid fill properties, such as fill color and transparency. In addition to the calculated area, you can display a description.

To calculate the area and perimeter by specifying internal point:

1. Type AreaNote at the command prompt.
2. Do one of the following:
   • On the menu, click Draw > Area Note.
   • On the ribbon, click Annotate > Revision > Area Note.
   • Type AreaNote.
3. Specify the Internal option, if it is not the default.
4. Optionally, specify the Settings option to define fill properties. See Area Note dialog box.
5. In the graphics area, click points in enclosed areas to define the boundaries of the area to calculate.
6. Press Enter.

To calculate the area and perimeter by specifying entities:

1. Type AreaNote at the command prompt.
2. Do one of the following:
   • On the menu, click Draw > Area Note.
   • On the ribbon, click Annotate > Revision > Area Note.
   • Type AreaNote.
3. Specify the Entity option.
4. Optionally, specify the Settings option to define fill properties. See Area Note dialog box.
5. In the graphics area, specify entities for which to calculate geometric areas (such as Circles, Ellipses, Arcs, or closed PolyLine contours).
6. Press Enter.

   The calculated values display. The displayed information depends on the type of the specified drawing entity. For example, for Circles and Ellipses the command displays area and circumference.

To annotate the area and perimeter by specifying points:

1. Type AreaNote at the command prompt.
2. Do one of the following:
   • On the menu, click Draw > Area Note.
   • On the ribbon, click Annotate > Revision > Area Note.
   • Type AreaNote.
3. Specify the Vertices option.
4. Optionally, specify the Settings option to define fill properties. See Area Note dialog box.
5. In the graphics area, specify points that comprise an area to annotate.

   The defined area highlights dynamically in the graphics area as you specify points.

   

   If you want to use specific points from drawing entities, for instance, a start or end point of a drawing entity, use the EntitySnap functions.

6. Press Enter when you finish specifying points.

   The calculated area display.

To calculate combined areas:

You can calculate the total area of several adjacent regions by specifying points or by selecting entities. Define an area by specifying points or using the Entities option.

1. Type AreaNote at the command prompt.
2. Do one of the following:
   • On the menu, click Draw > Area Note.
   • On the ribbon, click Annotate > Revision > Area Note.
   • Type AreaNote.
3. Specify the Entity option.
4. Specify the Settings option and press Enter.
5. In the Area Note dialog box, do the following:
   • In Mode, disable Create area note for each boundary.
   • In Boundary, click Specify internal points.
6. In the graphics area, click within each of the adjacent boundaries for which to calculate the area.
7. Press Enter.
8. In the Area Note dialog box, click OK.

   The combined area is calculated.

   Note: If areas intersect, the intersection area is subtracted from the main area.

The Area Note Dialog Box

General

Groups options for specifying what to display in the area annotation.

• Description. Lets you type a description to label the area.
• Calculated area. Displays the calculated area of a specified boundary.
• Show the area perimeter. When enabled, the command calculates the perimeter of the specified area.
• Current drawing units. Shows the unit system of the specified drawing.
• Show units format in. Lets you convert the calculated area value into other units.

Mode

Groups options for combining areas.

• Create area note for each boundary. When enabled, the command adds an area note for each specified boundary. Otherwise, the command calculates the combined area of the specified boundaries.
• Number area note boundaries. When enabled, the command automatically numbers annotated boundaries and labels areas with a number.

Boundary

Boundary Options

Button	Function	Description
	Specify boundaries	Lets you specify closed entities as boundaries.
	Specify internal points	Lets you click points in enclosed areas to define the boundaries.
	Create new boundary	Lets you define enclosed area by specifying points.

Settings

Groups options for customizing the solid fills.

• Transparency. You can set the transparency level for each filled area.
• Color. Lets you specify the color of the solid fill.
• Text style. Lets you specify the style for the label text.
• Text height. Lets you modify the text height.

  Specifies the text height for subsequent or selected text. Select a value from the list or type a value. The text height is the distance from the baseline to the top of a regular uppercase glyph (cap line) and is also known as the cap height.

• Format. Lets you set the units format: Decimal or Scientific.
• Precision. Lets you set the precision of the area value from 0 to 8 decimal places.
