Automatic Elevation Dimensioning

Module(s): Dimension Lines

You can use the Automatic Elevation Dimensioning tool to automatically dimension the elevation of existing architectural components. Draw a line through the components. The points at which the line and the components intersect are automatically dimensioned.

To dimension elevation points automatically

1. Click Automatic Elevation Dimensioning (How).
   

   Activate Automatic Elevation Dimensioning in one of the following ways

   • Menu bar: Create Dimension Lines

   • Toolbar: Basic Tools Dimension Lines flyout
   • Palette: Tools Create area in the following module(s):

   Dimension Lines

2. If you want, you can now modify the dimension line's parameters.
   Use one of the following options provided on the Context toolbar.
   

   • Click Properties to set the parameters in a dialog box.
   • Click Match to copy the settings form an existing element.
3. Define the position of the dimension line.
   

   • Through point: To set the position of the dimension line freely, click a point through which the dimension line is to pass.
   • Which dimension line: To create the dimension line at a defined distance from an existing dimension line, click just beside the existing dimension line. Make sure you click beside the side on which the new dimension line is to be created. The system will snap to the dimension line and display it in the selection preview color.
     
     
4. Define the angle of the dimension line in one of the following ways:
   • click two direction points.
   • enter the angle in the dialog line and press Enter to confirm.
   • click a line which you want to use as direction line.
5. Place the first point of the section clipping line.
6. Place the next points of the section clipping line (it is displayed as a construction line).
7. Press ESC to finish entering the dimension line.
8. Specify the position of the reference point.
9. Enter the corresponding base value (in the case of buildings, it is usually 0.00).

   The dimension line is displayed on-screen. The reference points are placed on the points where the clipping line and the dimensioned element intersect.

To produce a dimension line with extension lines, the Extension lines option in the Dimension Line Settings dialog box must be enabled.

No extension lines

When this option is enabled, no extension lines are drawn.

Bounded by user polyline (not with Elevation)

The extension lines can be drawn as far as an auxiliary polygon that you enter after creating the dimension line. This way, you can have the extension lines stretch so that they are at a set distance from the dimensioned components.

The offset you enter is interpreted as a positive or negative offset depending on the direction in which the polyline is entered. The following applies: A positive is applied to the right of the direction in which the polyline is entered.

To reference point (with Elevation only)

The extension lines are drawn as far as the reference point.

Predefined length

When this option is enabled, all the extension lines are drawn at a constant length and stretch towards the dimensioned points. With Auto Dimensioning and Automatic Elevation Dimensioning, you need to place an additional point that defines the direction of the extension lines.

Note: The clipping line is always parallel or perpendicular to the dimension line.
