Adding Datum Geometry to Combined States

It may still be necessary to add a few datum items to a combined state for clarity purposes.

• Specific datum entities for clarity: Datum axes, planes, points.

• Displaying all datums can become too cluttered.

• Three methods, depending on geometry: Show annotations

• Use combination states

• Create custom layer state

Adding Datum Geometry to Combined States

Once all annotation elements have been added to annotation features, and any additional surface references have been associated, it may still be necessary to add a few datum items to a combined state for clarity purposes. Displaying all datums can become too cluttered. Rather, it is desired to display only the chosen datum entities specific to that combined state. There are three different methods you can use to add datum geometry to combined states, depending on the type.

Showing Annotations

Figure 1 - Viewing Feature Datum Axes

Figure 2 - Viewing Feature Datum Axes Datum axes that are part of features can be displayed in a combined state by clicking Show Annotations

from the Manage Annotations group. You can then select the feature that the datum axes belong to and enable the display of those specific axes for the combined state. The selected datum axes display in both the detail tree and graphics window.

Using Combination States

If the Supplemental Geometry visibility check box is selected when you redefine a combination state, you can right-click on any supplemental geometry in the graphics window or model tree and select Assign. The supplemental geometry is added to the detail tree and displays in the graphics window.

Using Layer States

If the Supplemental Geometry visibility check box is cleared, then supplemental geometry display in the combination state is handled by the layer state assigned to that combination state. With this behavior, the detail tree is grayed out. Use the following procedure to display datum geometry using layer states:

• Create a new appropriately named layer state for the desired combination state.

• Redefine the combined state and assign the newly created layer state to it.

• Unhide the layer that the desired entities belong to.

• Hide all other entities on the layer.

• Re-save the layer state to capture the updated layer display.

Steps

• Task 1. Display datum axes in a combined state. Disable all Datum Display types.

• In the ribbon, select the View tab.

• Enable Plane Tag Display and Axis Tag Display from the Show group.

• Select the Annotate tab. Select the 7B combined state tab.

• Click Show Annotations from the Manage Annotations group.

• In the Show Annotations dialog box, select the Datums Tab .

• Select the hole feature as shown.

• In the Show Annotations dialog box, select the A_2 and A_3 check boxes. Click OK .

• Click in the background to de-select all geometry.

• Task 2. Display datum planes in a combined state. Select the 7D combined state tab.

• Notice the layer state assigned to this combined state is 0_ALL_ON .

• Right-click the 7D combination state tab and select Redefine .

• Notice that combination states are handling the visibility for annotations and supplemental geometry. Click OK .

• Enable Plane Display .

• In the model tree, right-click datum plane DTM3 and select Assign .

• Click in the background to de-select all geometry.

• Select the View tab and disable Plane Tag Display and Axis Tag Display .
