Editing Dimension Extension Line Properties

This task explains how to access and, if needed, edit dimension extension line properties.
Open the Brackets_views02.CATDrawing document. Create a diameter dimension, for example.
1. Select the dimension you created (whatever the type).

2. Select the Edit-> Properties command.

You can also right-click on this dimension and then choose Properties from the contextual menu.

3. In the Properties dialog box that appears, click the Extension Line tab. The associated panel is displayed.




Color: choose a color for the extension line.
Thickness: specify the thickness of the extension line.
Display first extension line: check to display or uncheck to hide the first extension line, when applicable.
Display second extension line: check to display or uncheck to hide the second extension line, when applicable.
Slant: set the slant angle for the extension line. This angle is contained between 90 degrees and -90 degrees excluded, the default angle being 0 degree.
This functionality works only on linear dimension line and the line linking extension line anchor points (blanking excluded) has to be parallel to the dimension line, as shown below.


Extremities: it allows you to increase or decrease extension line Overrun and Blanking.
Overrun is the overrun minimum value. As an example, for a cumulated dimension (for ISO Standard):

To set extension line length and text position for cumulated dimensions, use the CUMLExtMode dimension parameter in the standards.

the Height,
the Angle,
the Width,
the funnel mode: external or internal

the Funnel side allows you to apply funnel only on one extension line or both of them.
You cannot create interruptions on funneled dimension lines.
