This tutorial follows the ASME standard for defining GD&T. For other models, you can change the standard in the 
Preferences in the Model Settings category.
We will add variation to the Bracket using GD&Ts on the surfaces of the part. Recall that Feature Points will vary with the surfaces while Coordinate Points will not. Coordinate Points must be directly added to a GD&T in order for them to vary. GD&T will be added to the Bracket according to the print shown below.
First, we must define the datum features of the Bracket. The datum features need to be defined before we can created the datum reference frame (DRF) for the other callouts. We will start with the A datum features which are highlighted in the image below.
•Click 
GD&Ts then select the Bracket. This will open the GD&Ts dialog.
•Select Datum Feature as the type from the drop-down list next to [Add].
•Click [Add]. This will open the GD&T dialog for Datum Features.
•Change the Name to "A_Datum_Features".
•In the Datum Feature tab, select [Add].
•Select the three surfaces highlighted in the image below. These surfaces are the A datum features in the print.
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Verify the Label is "A".
The completed GD&T dialog should look like the image below. Your CadSurf numbers may be different.
•Select [OK] in the GD&T dialog.
Next, we will add the size tolerance for the B datum feature.
•Select Size as the type from the drop-down list next to [Add] in the Actions area.
•Click [Add]. This will open the GD&T dialog for Size.
•Change the Name to "Size_Hole_B".
•In the Tolerance tab, in the Features section, click [Add].
•Click the hole highlighted in the image below (click the cylindrical surface, not the edge).
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Select Ø diametrical for the zone type.
•Enter 0.1 for Upper value.
•Uncheck Symmetric (so there is no check in the checkbox).
•Enter 0mm for the Lower value. The completed dialog should look like the image below. Your CadSurf number may be different.
•Click [OK] in the GD&T dialog.
That is all we need for the size tolerance. Now, we will specify the hole as the B datum feature.
•In the GD&Ts dialog, select Datum Feature as the type.
•Click [Add]. This will open the GD&T dialog for Datum Features.
•Change the Name to "B_Datum_Feature".
•In the Datum Feature tab, click [Add] in the Features section.
•Click the same hole used for the size tolerance (highlighted in the image below).
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Verify the Label is "B".
•Click [OK] in the GD&T dialog.
Datum feature C is a slot. We will create the size tolerance on it next.
•In the GD&Ts dialog, select Size as the type from the drop-down list.
•Click [Add].This will open the GD&T dialog for Size.
•Change the Name to "Size_Slot_C".
•In the Tolerance tab, click [Add] in the Features section.
•Select the slot O_Fixture_Z in the Bracket. You can select the slot in the tree or in the graphics. Alternatively, you could select the two surfaces that were used to define the slot.
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Select blank (not diametrical or spherical) for the zone type.
•Enter 0.1 for Upper value.
•Uncheck Symmetric (so there is no check in the checkbox).
•Enter 0mm for the Lower value. The completed dialog should look like the image below.
•Click [OK] in the GD&T dialog.
Now, we will specify the slot as the C datum feature.
•In the GD&Ts dialog, select Datum Feature as the type.
•Click [Add].
•Change the Name to "C_Datum_Feature".
•In the Datum Feature tab, click [Add] in the Features section.
•Select the slot O_Fixture_Z in the Bracket.
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Click [OK] in the GD&T dialog.
Now we will add the surface profile for the four surfaces of the Bracket that the Headlamp and Turnlamp contact.
•In the GD&Ts dialog, select Surface Profile for the type and click [Add].
•Change the tolerance Name to "Surface_Profile".
•In the tolerance Description, enter "Surface profile at mounting holes."
•In the Tolerance tab, click [Add] then select the four surfaces of the Bracket highlighted below (every feature marked "S" in the drawing). The order does not matter. These surfaces control the variation of the primary planes to the two lamps.
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Set the Range to 1 mm.
We haven't created a datum reference frame (DRF) yet so we will do that now.
•Select the [Edit DRFs...] button in the lower-right of the Tolerance tab.
•In the Datum Features list of the Edit DRFs dialog, click A_Datum_Features. This will add the label "A" to the first DRF field.
•Next select B_Datum_Feature then C_Datum_Feature. This will add the labels "B" and "C" to the second and third DRF fields.
•Click [Add]. This will add a DRF with reference A | B | C to the Datum Reference Frames list. This can now be used in the tolerance.
•Select the [OK] to return to the GD&T dialog.
•Select A | B | C from the drop-down menu to set it as the DRF for the profile tolerance. The completed dialog should look like the image below. Your CadSurf numbers may be different.
•Click [OK] in the GD&T dialog.
Next we will add Size and Position tolerances for the holes to the Headlamp and Turnlamp. The tolerances will be created according to the call outs highlighted below. Because the Size and Position are the same tolerances, only applied on different nominal size holes, we can create the tolerances for all five holes at the same time.
It can be good modeling practice and is helpful when looking at results to group the features by their function. In this case, we have five holes, three are used to mount the Turnlamp, and two are used to mount the Headlamp, so we will create two separate callouts in 3DCS. First we will create the Turnlamp holes callout.
•In the GD&T list dialog, select Size for the type and click [Add].
•Change the Name to "Hole_Size_Turnlamp".
•For the Description, enter "Size of Turnlamp mounting holes."
•Click the [Add] button then select the three holes of the Bracket highlighted below (the holes associated with the Turnlamp).
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Set the Upper to 0.25.
•Leave the Symmetric checkbox checked. This makes the Lower symmetrically opposite at -0.25.
This completes the size tolerance. Now we will add the position.
•Click [+] to add a new frame.
•Change the name to "Hole_Position_Turnlamp".
•Add a description of "Turnlamp mounting hole position."
•In the new frame, change the type to 
Position.
•Set the zone type to Ø diametrical,.
•Set the Range to 1.
•Select 
Maximum Material Condition as the material condition
•Select A | B | C as the DRF. Each DRF only has to be defined once then it can be reused for multiple tolerances.
The completed Size and Position tolerances for the Turnlamp holes in the Bracket will look like the image shown below. Your CadSurf number may be different.
•Click [OK] in the GD&T dialog Size and Position tolerances.
Next we have to add the size and position tolerance to the two Headlamp mounting holes. The two holes included in these tolerances are highlighted below.
•Repeat the steps from above to create a size tolerance called "Hole_Size_Headlamp" and description "Size of Headlamp mounting holes."
•Repeat the steps from above to create a position tolerance called "Hole_Position_Headlamp" and description "Headlamp mounting hole position."
The completed Size and Position tolerances for the Headlamp holes in the Bracket will look like the image shown below. Your CadSurf number may be different.
Now the slot to the Headlamp needs to be toleranced for Size and Position.
•In the GD&Ts dialog, select Size as the type then click [Add].
•Change the Name to "Slot_Size".
•Change the Description to "Size of Headlamp mounting slot."
•Click [Add] and select the feature slot T_HeadLp_Z in the Bracket. You can select this from the graphics window or the tree3DCS Model Navigator.
•Click [OK][Close] in the Pick FeatureSelect dialog.
•Select blank for the zone type.
•Set the Upper to 0.25 and leave the Symmetric checkbox checked.
•Click [+] to add a new frame.
•Change the name to "Slot_Position".
•Add a description of "Position of Headlamp mounting slot."
•Change the new frame tolerance type to Position.
•Set the zone to blank, set the Range to 1, set Maximum Material Condition as the material condition, and select A | B | C for the DRF.
The completed Size and Position tolerances should look like the image below.
•Click [OK] in the GD&T dialog for Slot Position.
The GD&Ts dialog should look like the following image.
•Click [OK] in the GD&Ts dialog.
You can visualize the tolerances on the parts to verify they are varying as intended.
•If the mesh is off, click 
Show Mesh to turn the mesh on.
•Go to 
Creation Mode if not already there.
•Click the 
Deviate button.
•Zoom in on the Bracket to inspect the deviating features.
•Click [Close] in the Deviate dialog after you have verified the features are deviating as expected.
