OnShape Lesson 2.3 Vocabulary Assessment

The purpose of construction geometry in sketching is (a)  

• To create features directly
• to aid in construction w/o adding features
• To measure angles
• To convert sketches into 3D models

A "constrained" sketch in CAD is best described as a sketch that is (a)  

• A sketch with no dimensions
• A sketch that is fully controlled.
• A sketch that is only partially defined
• A sketch that is used for construction

How does the "revolve" feature function in CAD software?

• It creates a part by extruding a sketch linearly

• It creates a part by revolving sketches around a central axis

• It mirrors a sketch across an axis

• It scales a sketch to a larger size

Which unit is not part of the metric system?

• Millimeter

• Centimeter

• Inch

• Kilometer

What does the symbol Ø represent in technical drawings?

• Radius

• Diameter

• Circumference

• Area

How does design intent contribute to the stability of a CAD model when changes are implemented?

• Design intent ensures that changes to one component automatically update related parts.

• Design intent blocks any changes from impacting the design.

• Design intent allows modifications to one component to be independent of others.

• Design intent disregards changes in the design.

Why is it important to add dimensions to sketch geometries in CAD?

• To make the sketch look more complex

• To ensure the sketch is fully defined and accurate

• To convert the sketch into a 3D model

• To change the color of the sketch

In what scenario would you use a bearing in a machine design?

• To connect electrical circuits

• To reduce friction between a rotating part and its housing

• To increase the weight of the machine

• To measure the temperature of the machine

How does the use of metric units benefit international engineering projects?

• It simplifies communication by using a common measurement system

• It increases the cost of the project

• It limits the project to specific regions

• It complicates the design process

Elijah and Lily are working on a technical drawing for a new machine part. They need to understand the symbols used in the drawing. What is the difference between the symbols Ø and R in technical drawings?

• Ø represents radius, R represents diameter

• Ø represents diameter, R represents radius

• Both represent diameter

• Both represent radius
