Revolved cut in Solidworks - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a Revolved Cut in SolidWorks?

A Revolved Cut is a feature that removes material by revolving a 2D sketch around an axis, creating a cut with a circular shape.

beginner

Which sketch elements are essential for creating a Revolved Cut?

You need a closed 2D sketch and a centerline or axis around which the sketch will revolve to create the cut.

intermediate

How does the axis of revolution affect the Revolved Cut?

The axis of revolution determines the path around which the sketch is rotated to remove material, shaping the cut's geometry.

intermediate

Can a Revolved Cut be used to create asymmetric cuts?

Yes, by adjusting the sketch shape and revolution angle, you can create asymmetric cuts with a Revolved Cut.

beginner

What is the difference between Revolved Cut and Revolved Boss/Base?

Revolved Cut removes material by revolving a sketch, while Revolved Boss/Base adds material by revolving a sketch.

What is required to create a Revolved Cut in SolidWorks?

A A surface and a curve

B A 3D model and a plane

C Only a 3D sketch

D A 2D sketch and an axis of revolution

A Revolved Cut needs a 2D sketch and an axis to revolve around to remove material.

What does the axis of revolution do in a Revolved Cut?

A Defines the centerline for the sketch

B Determines the path for revolving the sketch

C Creates a new plane

D Adds material to the model

The axis of revolution is the line around which the sketch is rotated to cut material.

Which feature is opposite to a Revolved Cut in SolidWorks?

A Revolved Boss/Base

B Extruded Cut

C Fillet

D Chamfer

Revolved Boss/Base adds material by revolving a sketch, opposite to Revolved Cut which removes material.

Can you create a partial Revolved Cut by changing the revolution angle?

A Yes, by setting the angle less than 360 degrees

B No, it must always be 360 degrees

C Only if the sketch is open

D Only with a 3D sketch

You can create partial cuts by setting the revolution angle to less than 360 degrees.

What happens if the sketch for a Revolved Cut is not closed?

A The software will automatically close the sketch

B The cut will be created normally

C The cut will fail or produce unexpected results

D The cut will add material instead

A closed sketch is required; otherwise, the Revolved Cut may fail or behave incorrectly.

Explain how to create a Revolved Cut in SolidWorks step-by-step.

Think about sketch, axis, and revolve action.

Describe the difference between Revolved Cut and Revolved Boss/Base features.

Focus on add vs remove material.

Practice

1.

What does the Revolved Cut feature do in SolidWorks?

easy

A. Adds material by extruding a sketch

B. Mirrors a feature across a plane

C. Creates a flat surface on a part

D. Removes material by rotating a sketch around an axis

Solution

1. Step 1: Understand Revolved Cut purpose

   Revolved Cut removes material by spinning a sketch around a defined axis.

2. Step 2: Compare with other features

   Extrude adds material, mirror duplicates features, and flat surface creation is unrelated.

3. Final Answer:

   Removes material by rotating a sketch around an axis -> Option D

4. Quick Check:

   Revolved Cut = Remove by rotation [OK]

Hint: Revolved cut spins sketch to remove material [OK]

Common Mistakes:

• Confusing cut with extrude
• Thinking it adds material
• Mixing with mirror feature

2.

Which of the following is the correct syntax to start a Revolved Cut in SolidWorks?

Insert > Cut > Revolved Cut

easy

A. Insert > Boss/Base > Revolved Cut

B. Insert > Hole Wizard > Revolved Cut

C. Insert > Cut > Revolved Cut

D. Insert > Surface > Revolved Cut

Solution

1. Step 1: Recall menu path for Revolved Cut

   The correct menu path is Insert > Cut > Revolved Cut.

2. Step 2: Eliminate incorrect options

   Boss/Base adds material, Surface is for surfaces, Hole Wizard is for holes, not revolved cuts.

3. Final Answer:

   Insert > Cut > Revolved Cut -> Option C

4. Quick Check:

   Menu path = Insert > Cut > Revolved Cut [OK]

Hint: Revolved Cut is under Insert > Cut menu [OK]

Common Mistakes:

• Choosing Boss/Base instead of Cut
• Confusing Hole Wizard with Revolved Cut
• Selecting Surface instead of Cut

3.

Given a sketch of a semicircle with radius 10 mm and an axis along the diameter, what will be the result of a Revolved Cut feature?

medium

A. A solid hemisphere cut with 10 mm radius

B. A hollow sphere cut with 10 mm radius

C. A full cylinder cut with 10 mm radius

D. A hollow cylinder cut with 10 mm radius

Solution

1. Step 1: Understand sketch and axis

   A semicircle revolved around its diameter axis creates a solid hemisphere shape.

2. Step 2: Identify cut shape

   The Revolved Cut removes material in a solid hemisphere form, not a hollow sphere or cylinder.

3. Final Answer:

   A solid hemisphere cut with 10 mm radius -> Option A

4. Quick Check:

   Semicircle revolve = solid hemisphere cut [OK]

Hint: Semicircle revolve around diameter = solid hemisphere cut [OK]

Common Mistakes:

• Thinking it creates a hollow cylinder cut
• Confusing cylinder with sphere
• Assuming full cylinder cut

4.

Why does a Revolved Cut fail when the sketch is not closed?

medium

A. Because the sketch cannot form a solid profile to revolve

B. Because the axis is missing

C. Because the sketch is too complex

D. Because the material thickness is zero

Solution

1. Step 1: Understand sketch closure requirement

   Revolved Cut needs a closed sketch to create a solid profile for cutting.

2. Step 2: Identify failure cause

   An open sketch cannot form a solid shape when revolved, causing the feature to fail.

3. Final Answer:

   Because the sketch cannot form a solid profile to revolve -> Option A

4. Quick Check:

   Closed sketch needed for revolve [OK]

Hint: Sketch must be closed to revolve cut [OK]

Common Mistakes:

• Blaming missing axis instead of open sketch
• Assuming complexity causes failure
• Confusing material thickness with sketch closure

5.

You want to create a groove inside a cylindrical part using Revolved Cut. Which two things must you ensure before applying the feature?

hard

A. The sketch is closed and the part is flat

B. The sketch is closed and the axis is defined

C. The sketch is open and the axis is undefined

D. The sketch is open and the part is hollow

Solution

1. Step 1: Identify sketch requirements

   The sketch must be closed to form a valid profile for cutting.

2. Step 2: Confirm axis definition

   A clear axis must be defined to revolve the sketch correctly.

3. Final Answer:

   The sketch is closed and the axis is defined -> Option B

4. Quick Check:

   Closed sketch + defined axis = successful revolved cut [OK]

Hint: Always close sketch and define axis before revolved cut [OK]

Common Mistakes:

• Using open sketches
• Not defining axis
• Assuming flat or hollow part is required
