) method uses OCR

File) () method uses OCR
to identify the GD&T tolerance information to import.
You can access GD&T Selection Mode (from File) from one of these:
File | Import menu
For more information, see the "Using GD&T Selection Mode (from File)" topic.
Resolution
OCR detection works best with an image that has at least 300 DPI. Lower resolutions may produce less accurate results.
Supported FCF Types
The described OCR methods support these FCF types:
The 14 characteristic symbols
The Diameter symbol
M, L, P, and other modifier symbols bounded by circles
Data within the boxes and size data above boxes
Single-line tolerances, multi-line non-composite tolerances, composite tolerances
Unsupported Items
The OCR methods above do not support some complex elements. These include items like square brackets, extended characters, double-headed arrows, and so on.
FAQ
Question: What happens if my measurement routine already has a datum defined with the same label as a datum defined in the drawing?
Answer: If a datum definition with the same name already exists in your measurement routine, PC-DMIS does not request that you to create a new datum feature of the same name. Instead, PC-DMIS uses the existing datum feature from your measurement routine.
Question: Do I need to use OCR to recognize a datum all by itself?
Answer: No. Since datums are always defined for a GD&T tolerance, the OCR does not recognize them as separate GD&T notes. You only need define the GD&T tolerances and PC-DMIS prompts you to select the datum features as needed.
Question: What happens if there is size text immediately above the GD&T tolerance?
Answer: PC-DMIS parses this additional line and assigns the data to created FCF.
Question: What happens to multi-line non-composite GD&T tolerances?
Answer: PC-DMIS imports these as two separate FCF commands.
