Convert from Metric to Inch or vice versa

 

Instructions:

1. Create the QC Plan from a pdf drawing (for this example, let's assume the drawing is in Metric)
2. Make sure all (non-angle) dimensions have units set to "mm"
3. Once the QC plan is ready, click on the "Convert" tab above the QC Plan table
4. Select Convert from "mm to inch" [Note: If there are existing inspections using the plan, then the QC Plan conversion will fail. So please make sure you do this for a new plan, or delete any old inspections if needed.]
5. Your QC Plan will remain in "mm" to match the drawing
6. But when you create an inspection, you'll find that all features have been converted, and data now must be collected in "inch"
7. Finally, when you run any report, the data will be converted back to "mm" for reporting to the customer.

Conversion Display and Calculation:

Converted specs are displayed with an asterisk (e.g. 38.100 ± 0.253 mm*) that signifies the following:
1. Spec Display Precision:
-- When the spec is converted from mm to inch we display up to 5 decimal places in the spec.
-- When the spec is converted from inch to mm we display up to 3 decimal places in the spec.
2. Actual Precision:
-- However, Behind the scenes, we go out to 10 places after the decimal to ensure that in-spec and out-of-spec determination is always consistent between the original and converted units.
