Sometimes a low-quality drawing will cause the OCR to have difficulty accurately capturing the characteristics. Unfortunately, in some instances, updating your OCR Project Options will not solve this issue. This article will explain how to move forward if you cannot get the OCR to capture accurately.
If your drawing is low quality, and your attempts to improve the OCR have not worked, you can move forward by following the steps below to complete the extraction manually.
Balloon Your Drawing
Balloon your entire drawing as you normally would, ignoring the values captured by the OCR for now. We will come back and correct those later.
Manually Update Your Characteristic Properties
Once you have ballooned your entire drawing, select characteristic #1 in your table manager, and look to the Properties/Preferences Panel on the left side of your screen. There you will see the image that was captured at the top, and all of the extracted properties beneath it.
Here you will manually update all the properties (type, units, full specification, etc.) by clicking into each field with your mouse, and selecting from the dropdown or simply typing in the correct value. Simply choose the appropriate Tolerance Type and your tolerances will update automatically.
When you have finished updating the characteristic, use the right arrow (located in the upper right of the properties panel) to move on to the next characteristic. Continue updating all your characteristics until all the values are correct.
If the characteristic you are attempting to update contains a special character or symbol, use the symbol button (indicated by the omega icon) and select the symbol you need from the various subsets.
Building Feature Control Frames
If the characteristic you are attempting to update is inside a feature control frame, use the GD&T Builder in the Properties/Preferences Panel to update the value, as you normally would.
