CAD II - Chapter 3: Section of Solids

To understand some of the hidden geometry of components an imaginary plane is used to cut the object which is called _____________.

• auxiliary plane

• picture plane

• section plane

• additional plane

Which of the following is not the purpose of using a cutting (section) plane?

• Interpretation of object

• Visualizing of object

• Cutting the objects

• Invisible features

To find the true shape of the section, it must be projected on a plane parallel to the _____________.

• Profile plane

• Vertical plane

• Auxiliary plane

• Section plane

The type of line used to represent the cutting plane in the drawing is.

• 
• 
• 
• 

A section plane is parallel to the vertical plane (VP) the top view gives ___________ which is _________ to the xy line.

• true shape, parallel

• straight line, parallel

• straight line, perpendicular

• true shape, perpendicular

The projection of a section plane, on the plane to which it is perpendicular is a straight line.

• True

• False

The projection of section surface on the other plane to which it is inclined is called the auxiliary section.

• True

• False

The section plane is perpendicular to the Horizontal plane (H.P.) and inclined to the vertical plane (V.P.) the front view of section if section is a line. It ________________ xy line.

• is perpendicular to

• is parallel to

• is inclined to the vertical plane (V.P.)

• crosses

The section plane is perpendicular to the horizontal plane (H.P.) and inclined to the vertical plane (V.P.) the top view of section if section is a line. It ________________ xy line.

• is perpendicular to

• is parallel to

• is inclined to the vertical plane (V.P.)

• crosses

A section is perpendicular to both the reference planes the true shape and size are obtained by taking the projection of the section onto _________ plane.
