Understand Rounding and Precision
When you specify the display precision of units, the values for coordinates
and distances are rounded off. However, the internal precision of coordinates
and distances is always maintained regardless of the display precision.
For example, if you set the display precision of decimal-format units to 1 (or
0.0), the display of coordinates is rounded to one place after the decimal point.
Thus, the coordinates 0.000,1.375 are displayed as 0.0,1.4, but the internal
precision is still maintained.
Use a Drawing Template File
A drawing template file provides consistency in the drawings that you create
by maintaining your standard styles and settings.
Select a Drawing Template File
A set of drawing template files is installed with AutoCAD LT. Many of them
are provided either for imperial or for metric units, and some are optimized
for 3D modeling. All drawing template files have a .dwt file extension.
While these drawing templates provide a quick way to start a new drawing,
it is best to create drawing templates specific to your company and the type
of drawings you create.
Create a Drawing Template File
When you need to create several drawings that use the same conventions and
default settings, you can save time by creating or customizing a drawing
template file instead of specifying the conventions and default settings each
time you start. Conventions and settings commonly stored in template files
include
Unit format and precision
Title blocks and borders
Layer names
Snap and Grid spacing
Text styles
Dimension styles
Multileader styles
