Sectional Views Questions

• The visible lines adjacent to a revolved section may be broken out if desired.
• The pattern used for hatching a section can be something other than diagonal lines.
• In technical drawing a section view is often used to reveal some or all of an object's internal features.
• When a cutting plane line would obscure important details, just the ends of the line outside the view and the arrows can be shown.
• It is not acceptable to use the general-purpose symbol at different angles for different parts.
• In AutoCAD the Hatch tool is used to designate what pattern is to be used for a section view.
• The Cutting Plane line should be displayed at the same line weight as object lines.
• One of the outcomes of using section views in a technical drawing is the elimination of hidden lines.
• When a part is cut fully in half, the resulting view is called a half section.
• The ANSI 131 hatch pattern is the AutoCAD default hatch pattern.
• The section lines in all hatched areas for an object must be parallel.
• The Cutting Plane line reveals the type of material that the object is to be made from.
• Omit hidden lines from both halves of a half section whenever possible.
• If you set the ANSI 131 hatch pattern to an angle of 45 degrees the lines will be placed vertically.
• A section-lined area is always completely bounded by a visible outline.
• Removed sections should be labeled and arranged in order from right to left.
• Quarter sections expose the interior of one half of the object and the exterior of the other half.
• The preferred cutting plane line style is made up of equal dashes ending in arrowheads.
• The angle of revolution should always be less than 45 degrees for an aligned section.
• In offset sections, the bends in the cutting plane are typically shown in the sectional view.
