## Dimensioning Surface or Line Profile

Looking for XactMeasure GD&T dimensions? If so, see:

Dimension Surface Profile dialog box | Dimension Line Profile dialog box

The profile's Surface option computes the three-dimensional profile error of a surface or curve feature (Insert | Dimension | Profile | Surface).

The profile's Line menu option computes the two-dimensional profile error of a curve (Insert | Dimension | Profile | Line).

Note: The Profile dimension has changed from PC-DMIS 3.0 and earlier versions. You can now use any type of feature for a profile scan.

Important: By default PC-DMIS uses the 1983 ASME standard to calculate the measured value of a profile dimension. However, PC-DMIS 4.0 and higher allow you to switch between the current ASME standard and a newer ISO 1101 2004 standard. When doing a form and location profile dimension, the ISO standard calculates the measured value as 2 times the max deviation. The tolerance for this case is a diameter zone, all along the profile of the curve. This means the zone isn't just plus tolerance for one side and minus tolerance for the other. Additionally, the given single tolerance value is a diameter, not a radius.
To enable the ISO standard, access the PC-DMIS Settings Editor, navigate to the Option section and set UseISOCalculations to 1.
