PC-DMIS displays the tolerance zone for form dimensions as a linear graphic. For text mode reporting, this zone is comprised of characters with the number sign (#) indicating the amount of deviation. For non-text mode reports, this is shown as a bar graph with the bar growing larger from left to right as the deviation increases. For the non-text mode dimensions the color of the bar graph changes as deviations move towards out of tolerance.
For form dimensions (Straightness, Flatness, Circularity, and Cylindricity) there is no negative tolerance, so the linear graphic represents the deviation from perfect form (0 tolerance) where the extreme left of the graphic is 0 tolerance and the extreme right of the graphic is the maximum allowed tolerance.
Example Depicting Both Text Mode and Non-Text Mode Tolerance Zones
In the graphical example given above, the tolerance zone is indicated in both text-mode and non-text-mode with a deviation of 0.186 and a maximum tolerance of 0.3.
Here are some additional examples showing how a Circularity dimension's tolerance zone appears inside of PC-DMIS as a text-mode and non-text mode report respectively:
