### Default Axes for True Position Dimensions

The Default check box allows you to alter the format of the default output. When the Auto check box is checked, the axes displayed in the dimension are selected according to the default axes of the feature type. However, in some circumstances it may be necessary to override the default setting. To do this you would select the Default check box and any other desired axes.

To alter the output, simply select the desired check boxes:

Auto = prints the default axes based on the feature type.
X = prints X axis value.
Y = prints Y axis value.
Z = prints Z axis value.
Form = prints the integrated form dimension for the feature.
· For a circle or cylinder feature, this is the Roundness (RN) dimension.
· For a plane feature this is the Flatness (FL) dimension.
· For a line feature this is the Straightness (ST) dimension.
Pang = prints polar angle (PA) value.
Prad = prints polar radius (PR) value.
Default = Alters the format of the default output.

Once the output values have been changed to something other than the default, PC-DMIS will use the new setting for all subsequent dimensions. If you want to PC-DMIS to then use the original default axes, you must reset the format to the default settings.

To reset the format to the default settings:

1. Select the Auto check box.

2. Select the Default check box.

3. Click the Create button.

PC-DMIS will automatically reset the dimension to print the default axes according to feature type.

Note: If the Auto check box is marked, PC-DMIS will automatically determine the default axes to print. The default output format is based on the feature type. PC-DMIS will automatically determine the true position of the selected feature using the documented (see box above) axis format.
