Double-click the part.
Place this first part to the origo of the assembly
Instead of an indication, press the "Done" button (= V key of middle mouse button or Right-click function: OK.)
Use the Esc key to abort the addition of parts
If you press the V key or select the Right-click function OK, the program interrupts the addition of the selected part and asks you to select the next part to be added.
The program locks the first part in place by default, so you can't drag it.
Use a browser to add parts
The Add > Model function described above opens the so-called a model addition browser whose functions are trimmed to add parts to the assembly.
If you are using a universal browser that opens with the B key, click the part and drag it a short distance and release the mouse selection button to add the part to the assembly.
Double-clicking in the universal browser (B) does not add the part, instead it opens the model in separate window.
Add two teeth to the assembly
Right-click function: Add > Model.
Find the model, for example, in the History > Recent branch.
Click the tooth part and drag it a short distance and release the mouse selection button.
The program asks you to select a configuration.

Function: Coincidence (in the Ribbon).
Click the face of the body and face of tooth you want to add the considency.
Order 1) and 2) then 3) and 4).
Note that you can select the face behind the edge if the cursor is slightly outside the edge and there are no other faces under the cursor.
Add a constraints for both teeth.
OK:stop adding constraints.
Drag teeth
Click the tooth and hold down the mouse select button and drag the tooth.
The tooth slides according to constraints (as if it were moving on rails).
Place the centerline of the tooth on the centerline of the body
We can take advantage of the coincidency constraint and auxiliary levels because we extruded both the body and the tooth In both directions.
If we had not done so, then our teeth would have to be placed with a distance constraints.
Put the parts in place:
Restore the auxiliary geometry if it is hidden (G key).
First select body and tooth (Remember Ctrl key)
Right-click function: Constraints > Coinsidence.
The program stains the first part with attention color.
Click the auxiliary plane.
The program stains the second part with attention color.
Click the auxiliary plane.
The program announces: Assembly is fully defined!
Make a pattern of the first tooth
In this exercise, a teeth pattern is added to using the features pattern of the body.
Click to the first tooth, either from the model or feature tree.
Right-click function: Pattern.
In the Pattern Data dialog, change the location of the pattern: From New pattern to Fase from feature pattern.
Click on a face of feature.
The program deactivates the dialog fields (except for the Deleted field).
OK completes the pattern.
Make a pattern of the secont tooth
You can do the pattern in exactly the same way as above.
Or you can use a part in a pattern to create a new, similar pattern.
In the Pattern Data dialog, change the location of the pattern: From New pattern to Part from pattern.
The file also contains sub-models: Blade frame VX_PART10A and tooth VX_PART10B.
