Transition Pipe

The transition pipe is used to connect two pipe segments. The pipe has an outer diameter of 1.50" and an inner

diameter of 1.00" [1], fillets of 1/8" [2], and rounds of 1/16" [3]. Other dimensions are shown in the figure below. In

this section, we will create a 3D model for the transition pipe. Note that it is possible to create the curved pipe by

means of , however, as an exercise, we decide to create the curved pipe by using .
