Setting Working Units and Grid

	This task shows you how to set the units in which you will be working - inches or millimeters or yards and so on. It also shows you how to set the grid if you choose to have one.
	1.	To set the working units click on `Tools - Options`. Expand the General node, select`Parameters and Measure` and click the `Units` tab.
	2.	Under Magnitudes, select `Length` and click the drop down arrow to set the unit of measure you will be using; Millimeter, Meter, etc.
	3.	Now, scroll down the list in Magnitudes and select `Area`. Select the unit of measure you will be using for area. Note: This is normally consistent with the Length standard.
	4.	To set the grid click `Tools - Options` and, under `Options` click `Mechanical Design - Drafting` and then select the `General` tab.
	5.	In the Grid settings, check the `Display` option if it is not checked. For Primary Spacing enter 50 mm and for Graduations enter 5 mm. Primary Spacing refers to the bold lines in the grid. Graduations are the lighter gray lines.
