CREATING THE FIRST COMPONENT PART

In this section the entire model, except the T junction, will be created. The model to be created is composed of two pipes forming a 60-degree angle. To start with, the first pipe will be created. This pipe will then be rotated to create the second pipe.

Creating the profile

NOTE : To select the profile once the first rotation has been performed, first select all the lines and then delete those that do not form the profile. Use the option RotateTrackball from the mouse menu to rotate the model and make the process of selection easier.

Creating the union of the main pipes
