Figure 2.60b–f illustrates the steps to insert a newpart using the information of other parts in the assembly model (Fig. 2.60a). Firstly, the new part option under the insert tool is activated to begin the process of creating a new part in the assembly model. Secondly, the symmetric plane of the light body is selected as the associated sketch plane of the first feature of new part. Thirdly, the hole profile of the handle is projected on the sketch plane and converted as a circle in the sketch. Fourthly, an extruded feature is created by specifying the newly created sketch and two sides on the handle as the bounds on two extrude directions, respectively. Finally, a new part is fully defined, and the inserting process is terminated and returned to the assembly model with a newly created pin.
