True Position

Utilities

You need to know the basic dimensions of the drawing. This will calculate them for you.
1.
Put in the Tolerance according to the drawing.
2.
Check the Diameter checkbox if Diameter True Position.
3.
Fill in all the maximum and minimum dimensions from the drawing. This will calculate the
mean basic dimensions for you.
4.
Fill in the Actual X and Actual Y dimensions you measure on the part.
5.
If using Drawing Tolerance allows Maximum Material Condition, check the checkbox and fill in
the Actual Hole Diameter on the part.
No need to press Enter. Calculation is automatically updated whenever anything is changed.
When True Position calculated result is in RED, the value is out of tolerance.
Maximum Material Condition - MMC
If the tolerance callout has the M symbol then you are allowed extra tolerance. This extra tolerance
comes from how much the actual size of the hole is larger than the minimum allowed size.
Short-Cut Method
For the short cut way, if you already know how much the hole is off in the X and Y direction, you
can just put the deviation from basic in the Actual X and Actual Y boxes along with the Tolerance,
and leave all the other boxes blank.
MMC requires the min allowed diameter and the actual diameter of the hole.
Inch or Millimeter input doesn't matter as long as you use the same everywhere.
Radial or Diameter True Position.
Most tolerances on the drawings you see will have the diameter symbol in the feature control
frame. So .005 means the tolerance zone is a circle around the basic point with that diameter.
Without this symbol the .005 is a circle with that radius around the basic point - which is twice the
size.
Plus and Minus Dimensions
You can also enter dimensions in the plus and minus form to make it
easier if your drawing has this kind of dimensioning.
Using only the Max edit boxes, after the main number add plus and minus
symbol or just plus or just minus and then the second number, into the
Max dimension box.
You can also have 0.2525+.01-.005
The min, max and mean are automatically calculated from this. You can see the calculated mean
dimensions in parentheses.
This can also be used for Basic dimensions. If you have basic dimensions on the blueprint you can
put them in the Max box with a + or - on the end to signify a calculation. Like, 0.2525+
Printing
The Print button will print a picture of the form as shown on the screen.
