3D Modeling: Pear Cam Tutorial in Onshape

The video tutorial explains the concept of cams, focusing on creating a pair cam using specific dimensions. It guides through sketching in a part studio, adding construction lines, and finalizing the design with tangent lines. The process concludes with extruding the cam and preparing it for 3D printing. The tutorial ends with instructions for further tasks and encourages questions.

What is the primary function of a cam in mechanical systems?

• To provide electrical power

• To reduce friction

• To allow for various styles of motion

• To store mechanical energy

What is the thickness of the pair cam being created?

• 1/2 inch

• 1/4 inch

• 1 inch

• 3/4 inch

What is the diameter of the outer circle used in the pair cam?

• 1 inch

• 2 1/2 inches

• 3 inches

• 1 1/4 inches

What tool is used to ensure lines are tangent to circles in the cam design?

• Tangent tool

• Dimension tool

• Circle tool

• Line tool

What is the purpose of adding tangent lines to the cam design?

• To edit and refine the shape

• To ensure the circles are connected

• To create a 3D model

• To measure the diameter

What is the final step in completing the cam design?

• Extruding the shape

• Adding a fillet

• Drawing the circles

• Printing the design

What additional task is suggested after completing the pair cam?

• Designing a new cam

• Reviewing the video tutorial

• Creating other cams from the task list

• Submitting the design for review
