Drawing mechanical parts is different from artistic sketching - drawings must
be precise. To achieve this precision use the mouse to get the approximate size
or shape and then tune the drawing by typing numeric values. For example, to draw
a .500" circle draw a small circle with the mouse and then enter .500 in the diameter
edit box.
To change the position or size of lines numerically:
On the numeric bar located under the toolbar enter the desired numeric
values . You can specify " or inch or mm for millimeter after a numeric
value. You can also use / * + - signs to make appropriate arithmetic
operations. For example you can enter 3/16 instead of .1875.
Press Enter to register each numeric value.
To learn what each numeric value signifies, view the tooltip by moving the mouse
cursor to the associated icon in the running application.
