Measurement units in Autodesk Inventor 2012
Autodesk Inventor recognizes and processes most commonly used units of measurement. Every part, assembly, and drawing has a default units system. Values that you enter in dialog boxes are assumed to be in the default units unless you specify a unit name.
Changing the units system for a file
The default units are set when you create a file. However, you can change the units at any time. In part and assembly files, the units system is set in the document settings. In drawings, the units system is set by the dimension style and the active drafting standard. You can edit the dimension style or drafting standard to change the units system, or change the drafting standard for the drawing. When you change the units system, all existing values in the file are converted to the new units, and all subsequent entries are assumed to be in the new units.
Using templates to set the units system
When you installed Autodesk Inventor, you specified a units system that is automatically assigned to all new files. You can change the automatically assigned units by editing the templates used to create new files, or replacing the templates with your own.
Overriding the default units
As you enter values into dialog boxes they are assumed to be in the default units system for the file. You can override the default units for a single entry by adding the unit name after the value. For example, 0.05 in. or 3 mm.
