This chapter is about constructing dimensions. Figure 36 shows the notation that is used when referring to dimension parts.

36: Notation for dimensions.
Options Toolbar:
The dimensioning tools may show individual option toolbars, but also share one common toolbar. It allows you to enter a text label for the dimension:
This text label can be any text. When left empty, the label is generated
automatically and contains the measured distance (or angle) of the
dimension. To add additional signs or letters to a measured dimension, you
can use the combination
<>
to insert the automatically generated label anywhere
in the text you enter.
Examples:

The toggle button with the diameter sign can be used to show a diameter sign before the dimension label. Use the edit field right after that button to enter any text to be displayed as the label. The combo box contains some often used symbols. Select a symbol from the list to insert it into the edit field for the label. The two edit fields at the right are usually used to indicate tolerances. The first for the upper tolerance of a value (e.g. +0.1) and the second one for the lower tolerance (e.g. -0.05). See Figures 37 and 38 for an example.
Figure
37: These example options generate a
dimension label as shown in Figure
38.

CAD Toolbar:
Menu:
Dimension - Aligned
Hotkey:
da
Command:
dimaligned
Description:
Creates aligned dimensions. Aligned dimensions usually measure the length of an existing line (Figure 39). The dimension line is always parallel to the line between the two extension line endpoints.
Figure
39: Example for an aligned
dimension.
Procedure:
CAD Toolbar:
Menu:
Dimension - Linear
Hotkey:
dr
Command:
dimlin
Options Toolbar:
Description:
Creates linear dimensions. Linear dimensions are usually used to measure vertical or horizontal distances but can also measure distances with any other angle. Figure 40 shows a horizontal version of a linear dimension.
Figure
40: Example of a horizontal, linear
dimension.
Procedure:
CAD Toolbar:
Menu:
Dimension - Horizontal
Dimension - Vertical
Hotkey:
dh, dv
Command:
dimhor
dimver
Description:
These tools are provided for convenience and behave essentially like the tool described above (Linear Dimension). The only difference is that you don't have to enter an angle.
CAD Toolbar:
Menu:
Dimension - Radial
Command:
dimrad
Description:
Creates radial dimensions for circle or arc entities (Figure 41).

41: Example of a radial
dimension.
Procedure:
CAD Toolbar:
Menu:
Dimension - Diametric
Command:
dimdia
Description:
Creates diametric dimensions for circle or arc entities as shown in Figure 42.
Figure
42: Example of a diametric
dimension.
Procedure:
CAD Toolbar:
Menu:
Dimension - Angular
Command:
dimang
Description:
Creates angular dimensions between two reference lines as shown in Figure 43.
Figure
43: Example of an angular
dimension.
Procedure:
CAD Toolbar:
Menu:
Dimension - Leader
Hotkey:
dl
Command:
dimlea
Description:
Leaders are arrows that usually point from a text entity to an other entity as shown in Figure 44. In the example, the text entity "N7" is describing a surface property by pointing to it with a leader.
