How to Set Units in SketchUp

By Alan Sembera

The SketchUp 3-D modeling application makes it easy to change the units of measure for you drawing, and gives you several units from which to choose: inches, feet, meters, centimeters or millimeters. When you change the units for a drawing, it affects only that drawing. To change the default measurement units for new drawings, you must change your default template.

Change Units for Current Drawing

Step 1

Select "Model Info" from the "Window" menu.

Step 2

Select the "Units" tab in the Model Info dialog box.

Step 3

Select the unit of measurement you wish to use for the current model: either inches, feet, millimeters, centimeters or meters. If you select inches or feet, you can also choose to show them either as decimals or as fractions.

Step 4

Change the "Precision" setting to control how many decimal points show in your measurements. If you chose inches or feet, you can also control the fraction used, such as one-eighth or one-sixteenth of an inch.

Change Default Units

Step 1

Select "Preferences" from the "Window" menu.

Step 2

Select the "Templates" tab in the System Preferences dialog box.

Step 3

Select one of the templates from the list. Each template description includes the units of measure used in the template.

Step 4

Click "OK" to save your selection. Changing this setting does not affect any model you currently have open, but instead changes the units of models you create in the future. The units of measurement in the template also affect the default units in Layout mode.

  • If you use SketchUp Pro, you can access the unit controls in layout mode by selecting "Document Setup" from the "File" menu, and then selecting the "Units" tab.
