Creating a Half Dimension

Creating a Half Dimension

This section explains how to create a half dimension.
Notes
The value displayed in a half dimension is calculated as the distance between two specified points × 2.

Procedure:

[1] Click [Half Dim] in the [Annotation] tab.

[2] First, select a midpoint or center.
Press the Spacebar to display the menu, then click either [Mid Point] or [Center] and select a point.
Warning
If your keyboard is set to Japanese input mode, pressing the spacebar will not display the menu. In this case, you can also display the menu by pressing the Shift key while right-clicking.


[3] After selecting the Mid Point or Center, select the point to be dimensioned.

[4] Move the cursor to adjust the position of the dimension and click to finalize the placement.

[5] Press the Esc key to exit the Half Dimension command.

When [Half Dim] is selected, the instance menu will appear in the lower left of the screen.

Description of the Instance Menu

1. Length

You can switch between [Length] and [Diameter].
If [Diameter] is selected, the symbol “Φ” will be displayed in the dimension value.

2. Extend beyond extension Line

The leader lines are indicated by the red arrows in the diagram below.
The upper diagram shows an extension length of “5”, and the lower diagram shows an extension length of “1”.

3. Prefix

Symbols or text entered in the Prefix field will be displayed before the dimension.
If you have selected [Diameter] in section 1, entering “%c” will display the “Φ” symbol.

4. Postfix

Symbols or text entered in the Suffix field will be displayed after the dimension.

5. Basic Value

To change the measured dimension to a custom value, enter the desired dimension directly into this field.
