Units options

 

You can set the units for dimensions, the sketch grid, and text height.

To customize units

  1. Select DS Mechanical Options from the File menu to display the DS Mechanical Options window.

  2. Click Units from the navigation panel on the left.

  3. Select one of the following from the Units settings for drop-down list:

  4. Modify the options on the page.

  5. Click OK to save all your changes and close the window.

     

If you try to enter a value that is out of the allowed range in the Options panelClosed or the DS Mechanical Options dialog, you will see a red exclamation mark icon next to the field. You can hover over the icon to see a tooltip that will explain the valid values for the option.

 

Units

Type: Select Metric or Imperial from the menu.

Length: Select the default units used for length.

Decimal/fraction: If you use Imperial units, you can select Decimal or Fraction to display distance measurements that are less than 1 unit.

Angle: Select from the following options. For SCDM only, a checkbox to Use project units when available will be active only when you are modifying settings for all new documents. The option will be disabled by default. NoteClosed: When radians are chosen, their angle dimensions will show the appropriate values and unit suffix (rad).

MassClosed: Select the default units used for mass.

Density: Select Independent to specify the density units from the density fields or Derived to calculate the units from your selections for length and mass.

Symbol: Select the abbreviation you want displayed for unit type you selected for Length.

Primary precision: The number of decimal places you want displayed for distance measurements for the primary units.

Angular precision: The number of decimal places you want displayed for angle measurements for the primary units.

Show trailing zero: Select this option to display trailing zeros in decimal measurements.

Use tight tolerances: When this option is selected, tolerances are rounded to a value that gives a tighter tolerance when you have dual dimensions or when a dimension from the design window is shown in the drawing window with a different unit setting than the design window. The purpose is to not lose any precision when converting from one unit system to another. When this option is not selected, the values are rounded according to method A in ISOClosed 370-1975 (E). When selected, values are rounded according to method B.

Show symbol in user interface: Select this option to display the units abbreviation in DS Mechanical. The abbreviation will appear in measurement fields, such as a distance field when you pull a face.

Show symbol in annotations: Select this option to display the units abbreviation after the measurement in annotation dimensions.

Show "-" separator: Select this option to display a hyphen between whole values and fractions.

Use Dual dimensions: Select this option to display annotation dimensions in both Metric and Imperial. The unit type you have selected is displayed first and the other is displayed in square brackets. You can see a preview of the display below this option category.

Secondary precision: The number of decimal places you want displayed for distance measurements for the secondary units.

Show nearest fraction: Check this option to show the nearest fractional value Less Than the nominal dimension and the nearest fractional value Greater Than the nominal dimension. It allows for Ruler-style dimensions. For example, if you were to lay a ruler down and the distance falls between the marks on the ruler, these values tell you the nearest marks on either side of the dimension value.

Grid

Reset to Defaults: Click this button to reset the grid settings to the DS Mechanical defaults.

Minor grid spacing: Type the distance you want between the smallest grid lines.

Number of grid lines per major: Type the number of smaller grid lines between larger, darker grid lines.

Text

Text height units: Select a unit type for note text.
