the plan view. You can export drawings to other applications or cut objects
to the Clipboard and retain lineweight information.
In model space, lineweights are displayed in pixels and do not change when
zoomed in or out. Thus, you should not use lineweights to represent the exact
width of an object in model space. For example, if you want to draw an object
with a real-world width of 0.5 inches, do not use a lineweight; instead, use a
polyline with a width of 0.5 inches to represent the object.
You can also plot objects in your drawing with custom lineweight values. Use
the Plot Style Table Editor to adjust the fixed lineweight values to plot at a
new value.
Lineweight Scale in Drawings
Objects with a lineweight are plotted with the exact width of the assigned
lineweight value. The standard settings for these values include BYLAYER,
BYBLOCK, and Default. They are displayed in either inches or millimeters,
with millimeters being the default. All layers are initially set to 0.25 mm,
controlled by the LWDEFAULT system variable.
A lineweight value of 0.025 mm or less is displayed as one pixel in model
space and is plotted at the thinnest lineweight available on the specified
plotting device. Lineweight values that you enter at the Command prompt
are rounded to the nearest predefined value.
You set the lineweight units and the default value in the Lineweight Settings
dialog box. You can access the Lineweight Settings dialog box by using the
LWEIGHT command, by right-clicking the LWT button on the status bar and
choosing Settings, or by choosing Lineweight Settings on the User Preferences
tab in the Options dialog box.
