Units

After selecting the Units option from the selection tree located on the left side of the Job Preferences dialog, the right part of the dialog displays the options shown below.

The top part of the dialog contains the field for selection of the preference option set.

You can specify the work units in Autodesk AutoCAD Structural Detailing.

Select one of the following unit systems:

• imperial

  type:

  o   architectural (0'-0)

  o   engineering (0'-0'')

• metric.

There is also the Description and length format option which is used to parameterize the length unit. The option is applied only for dimensions and description of reinforcement length (reinforcement presented outside the drawing contour). You can select imperial or metric system for description. If the imperial format is selected, choose the engineering or architectural type. For metric format, the option is used to determine how to present length values less than 1m and length values over 1m. For example, if centimeters are selected in the format for < 1.0 mfield, then the dimension 0.33 m will be displayed as 33 cm.

In the bottom part of the dialog you select the units applied in the Autodesk AutoCAD Structural Detailing - Reinforcement dialogs. Units have been divided into the following categories:

• Length unit, including the following components: cover, spacing, reinforcement length, formwork dimensions, etc.
• Unit of reinforcement diameter
• Unit of reinforcement area
• Mass unit
• Number of decimal places for description and table styles.

Units are selected from the drop-down list available for each of the categories. For all the units, it is possible to change the manner of presenting the format of numbers of the quantities listed. These fields define the number of decimal places for each of the quantities. To change the number of decimal places, select the relevant item on the 2nd selection list to the right of the unit. The unit precision is reflected in descriptions of reinforcement, dimensions, etc. Note: Reinforcement tables have their own precision settings.
