Units Options
Specify how units are displayed
for the active part, assembly, or drawing document.
If you use small units such as
angstroms, nanometers, microns, mils, or microinches, it is helpful to
create templates
as the basis for documents that use the units. The templates could include
settings such as:
To set units for the active document:
Click Options or
Tools, Options.
On the
Document Properties tab, select
Units.
Select
from the options described below, then click OK.
Unit system
Select a unit system. Use the matrix below the options to specify configurable
options for your selection.
MKS
(meter, kilogram, second)
CGS
(centimeter, gram, second)
MMGS
(millimeter, gram, second)
IPS
(inch, pound, second)
Custom.
Lets you set the Length units,
Density units, and Force.
Matrix
The options you can select in the matrix depend on the open document
and the unit system you select. The matrix is divided into:
To
display dual dimensions, select Dual
dimensions display in the Detailing
options.
Select Length,
Mass, and Per
unit volume units. Mass properties involving length (such as volume,
surface area, center of mass, and so on) are based on this Length
unit rather than the length unit specified by the document unit system.
Units can be mixed; for example, moments of inertia are units of Mass*Length^2 and so can be grams*square
inches.
For all unit systems, you can specify decimal
precision.
For a Custom
unit system, you can specify units of Time, Force,
Power, and Energy .
Defining Precision
Where applicable, you can specify precision as Decimals
or Fractions. The
following rules apply:
Select up to 8 decimal places of precision.
For length dimensions under Basic
Units, if the unit selection is microinches,
mils, inches,
or feet & inches, you can
select Fractions instead of Decimals.
Under More:
If you specify Fractions,
you can select Round to the nearest fraction.
If your unit selection is feet
& inches, you can select Convert
from 2'4" to 2'-4" format.
The
format for feet & inches in
the SolidWorks software is 2'-4". If you import a document in the
2'4" feet & inches format,
you can convert the document to 2'-4".
Once you convert a document
to 2'-4" format, you cannot convert back to the 2'4" format.
