Create an Assembly

Now you build a new assembly based on the skeleton part.

1. Start an assembly based on the Standard(mm).iam template.
2. On the ribbon, click Assemble tab Component panel Create . In the Create In-Place Component dialog box:
   • Enter Strap as the name of the new component.
   • If your standard part template is inch-based, click the Browse Templates button to the right of the Template list. Click the Metric tab of the Open Template dialog box, and then select the Standard(mm).ipt template. Click OK to return to the Create In-Place Component dialog box.
   • Click OK to create the Strap part in the assembly.
   • Expand the Origin folder in the Model browser, and place the component on the XY Plane of the assembly origin.
3. Click Finish Sketch on the ribbon to exit the sketch environment.
4. Delete Sketch1 in the Strap part to tidy up the Model browser.
5. Click Manage tab Insert panel Derive . From the Tutorial Files folder, select the SkeletonBase.ipt file and open it. The Derived Part dialog box opens.
6. The Strap part requires only the CIRC STRAP SKETCH. Expand Sketches in the Derived Part dialog box. Select the CIRC STRAP SKETCH node, and click the Add button (+) at the top of the dialog box. Alternatively, you can click the Exclude icon on the node itself to switch its status.
   

   You may receive a warning that the base component will be modified. It is fine. Click OK to allow the sketch to be exported.

7. If the Work Geometry icon is in a hybrid state (half yellow and half gray), click the icon to change it to an Exclude state .
   Note: Sketches, surfaces, and work geometry must be visible in the originating part to derive into the new part. You can turn off the visibility of items before using the Derived Component command. It reduces the number of items you must clear in the dialog box.
8. Ensure the icons next to Surfaces Bodies and Parameters are set to the Exclude state.
9. Click OK and reposition the geometry in the graphics window. Click Return. The part should match the following image.
   
10. Click 3D Model tab Create panel Revolve . Select the closed profile of the strap.
11. Click Axis in the Revolve dialog box, and then select the line highlighted in the following image.
12. Click OK to create the Strap part.
    
    Tip: You can add features to the part as you can with any part created from scratch. The derived sketch controls the size and position of the base feature in this example. You can use Derived Component at any point in the modeling process, not just as the first feature in a part. For example, a second feature derived from the component might bring in a second sketch, It is then used to add or subtract geometry from the first feature based on the derived component.
13. Click Return on the Quick Access toolbar to return to the assembly level.
14. Save the assembly. Use Skeleton.iam for the file name.
