19. Intersecting pipes

This exercise shows the use of the Boolean tool to draw intersecting pipes.

Draw the base (circle)

q Tool: 2D Drawing tool, Circle q Do it: Face view (2), then top view (5). Draw a circle. q See the detailed explanations in the chapter: User Manual/Tools/Drawing/Circle

Make a cylinder

q Tool: Extrusion q Do it: 1. Face view (2). 2. Extrude the Circle (with a vertical constraint) toward the top. 3. Then click on the two red faces to close them. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Extrusion, User Manual/Tools/Assistant Palette/Cursor movement and positioning constraints

Making the crossing

Þ Step 1: Copy while rotating

q Tool: Rotate (+Control) q Do it: 1. To do the crossing, we simply, while holding the Control key pressed, select the Rotate tool. 2. Then, click on the center of gravity of the cylinder and rotate 90°. 3. When leaving the tool, we can see we have made a perpendicular copy of the cylinder. q See the detailed explanations in the chapter: User Manual/Tools/Assembly/Rotation

Þ Step 2: Finish the crossing

q Tool: Boolean q Do it: Now, do a Boolean operation to produce a single object. q See the detailed explanations in the chapter: User Manual/Tools/Modeling/Cut/Boolean
