The following is intended to provide a more detailed outline of what your
dimensions will look like if you use “Feet & Inches” for your units.
You can change your display units by going to "ToolsOptionsDocument
PropertiesUnitsCustom - Feet & Inches."
Here is a default "IPS (inch, pound, second)" display. SolidWorks is using the values from columns A and B.
We now want our UNITS to display as "Feet and Inches".
First, we must set "Unit System" to "Custom" then column A to "feet & Inches".
As you can see, 13.2150 changes to a feetdecimal format.... 1' 1.2150."
is a Denominator or number of total pieces a whole is divided into.
IE, Cut a pie in 4 slices, the denominator is 4. The decimal
equivalent would be 0.250.
If we set column C - Fractions to a value (i.e., 4), the 13.2150 does not change to a fraction. That is because the decimal value is not a divisible fractional value of 1/C value. Because C = 4,
the decimal would need to be 13.25, 13.50 or 13.75. Then it would
switch to 1' 1-1/4", 1' 1- 1/2" or 1' 1-3/4" respectively.
If you ALWAYS want a decimal value to display as a fraction, (excluding whole numbers), you need to set column D to "Round to nearest fraction."
Important to note, if you input a value of say 1.200", it will display as 1
1/4." This is only graphical. The TRUE length of it is still 1.200."
It's just rounding the display value.
In this case, C = 4 => 1/4 => 0.2500
With our initial length being 13.215 and C evaluating every .25", the evaluation range is 13.25 -- 13.215 --13.00.
Thus 13.215 is within .035 of 13.25 so it rounds up to 1/4".
This results in the 1' 1- 1/4" Value. The larger C is, the closer the fractional display will be to the actualtrue line length.
