### Default Axes for Location Dimensions

When the Auto check box in the Axes area is checked, the axes displayed in the dimension are selected according to the default axes of the feature type, but are grayed out:

If you select multiple features of different types (for example a circle feature and a point feature), the Axes area will select the axes to use for the last selected feature:

In some circumstances it may be necessary to override the default setting. The Default check box remains available so you can alter the format of the default output.

To alter the default output:

1. Select the feature(s) to dimension.

2. Select the Default check box. The Auto check box is cleared and all axes become available for selection.

3. Select the appropriate axes as needed.

X = prints X axis value.
Y = prints Y axis value.
Z = prints Z axis value.
Prad = prints the Polar Radius.
Pang = prints the Polar Angle.
D = prints Diameter value. For an ellipse, this is the minor diameter value (same as H).
R = prints Radius (half of Diameter) value.
A = prints Angle value.
L = prints Length (used for cylinder, cones, slots, and ellipses.) For an ellipse, L gives you the major diameter value.
H = prints the Height (used on cones, cylinders, and ellipses). For an ellipse, H gives you the minor diameter value.
V = prints the Vector location.
Form = prints the feature's integrated form dimension with the location dimension

- For a circle, cylinder, or cone 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.

3. Click the Create button.

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 Default check box.

2. Select the Auto check box. All the axes check boxes become grayed out.

3. Select the feature(s) to dimension. The original default axes are selected.

4. Click the Create button.

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