Sections 13.01-13.13 of Text
• Engineering 1182
Objectives • Learn about the different types of section
views• Decide what category of section view
should be used for particular circumstances
• Create half section views such that they adhere to accepted engineering drawing practices
• Engineering 1182
Section Views
• Although we will only focus on full and half sections in this class, there are many different types of section views: – Offset sections – Removed sections– Revolved sections– Broken out sections
• Engineering 1182
Offset sections
• Offset sections are used to capture internal details of parts where not all details line up along a single cutting plane.
• Engineering 1182
Removed and Revolved Sections
Removed Sections• Shows only ‘new’
surfaces created by a cutting plane.
Revolved Sections• Similar to a removed section,
but it super-imposed onto the object at the location of the cutting plane
• Engineering 1182
Broken-Out Sections• Broken-out sections are used when the
internal detail to be revealed is only a small part of the whole object.
• Engineering 1182
Half Sections
• Half sections are used to save time and space in engineering drawings and are most commonly used for symmetric parts.
• The steps for creating a half section are the same as those for creating a full section, but only half of the object needs to be revealed.
• Hidden lines are not shown on the un-sectioned portion of the section view.

Half Sections
• Engineering 1182
Creating Half Sections• Step 1: Draw the cutting plane and
choose the viewing direction. • Step 2: Outline the base; a
centerline divides the sectioned half from the solid half
• Step 3: Identify intersection points with the cutting plane and see what is happening on the adjacent view.
• Step 4: Outline internal features associated with the intersection points on the cutting plane.
• Step 5: Find the boundaries of air and solid and cross-hatch the solid areas.
• Step 6: Add new edges that were revealed and centerlines where appropriate. CLICK
