Section view creation in Solidworks - Step-by-Step Guide

Introduction

Section views help you see inside a 3D model by cutting it open. This makes it easier to understand complex parts and check internal features without hiding or removing anything.

When you want to inspect the inside of a mechanical part without disassembling it.

When you need to show hidden features clearly in a drawing for manufacturing.

When you want to check if internal components fit together properly.

When presenting a design to explain how internal parts work.

When verifying that holes, slots, or cavities are correctly placed inside a model.

Steps

Step 1: Open

- your 3D model in SolidWorks

The model appears in the main workspace.

Step 2: Click

- the 'Section View' button on the Heads-up View toolbar

The Section View PropertyManager opens on the left side.

Step 3: Select

- a plane or face in the model to define the cutting plane

A preview of the section cut appears on the model.

Step 4: Adjust

- the position of the cutting plane by dragging the arrow or entering a distance value

The section view updates to show the cut at the new position.

Step 5: Choose

- the direction of the cut (flip side if needed) in the PropertyManager

The section view flips to show the opposite side of the cut.

Step 6: Click

- 'OK' or the green checkmark in the PropertyManager

The section view is created and displayed in the workspace.

Step 7: Save

- your model or drawing to keep the section view

The section view is saved with your file.

Before vs After

Before

The 3D model shows all external surfaces with no internal details visible.

After

The model displays a cut through the selected plane, revealing internal features clearly.

Settings Reference

Cutting Plane Selection

📍 Section View PropertyManager

Defines where the model will be cut to create the section view.

Default: No plane selected

Cutting Plane Offset

📍 Section View PropertyManager

Moves the cutting plane forward or backward from the selected plane.

Default: 0 (on the selected plane)

Flip Direction

📍 Section View PropertyManager

Changes which side of the plane is shown in the section view.

Default: Off

Show Section Cap

📍 Section View PropertyManager

Displays the cut surface with a hatch pattern to highlight the section.

Default: On

Common Mistakes

Selecting a non-planar face or edge as the cutting plane.

Section views require a flat plane to cut through the model cleanly.

Always select a planar face or a reference plane for the cutting plane.

Not adjusting the cutting plane position, resulting in cutting through an unimportant area.

The default plane may not show the internal features you want to inspect.

Use the offset control to move the cutting plane to the area of interest.

Forgetting to flip the cut direction when the section view shows the wrong side.

The section view may hide the features you want to see if the cut direction is wrong.

Use the flip direction option to show the correct side of the cut.

Summary

Section views let you see inside a 3D model by cutting it open along a plane.

You must select a flat plane and can adjust its position and direction for the best view.

Remember to save your work to keep the section view for later use.

Practice

1. What is the main purpose of creating a section view in SolidWorks?

easy

A. To show hidden internal details by cutting through the model

B. To change the color of the model

C. To add textures to the surface

D. To create a 3D animation of the model

Solution

1. Step 1: Understand what a section view does

   A section view cuts through a model to reveal hidden internal features that are not visible from the outside.

2. Step 2: Identify the correct purpose

   Changing color, adding textures, or animations are unrelated to section views.

3. Final Answer:

   To show hidden internal details by cutting through the model -> Option A

4. Quick Check:

   Section view = reveals hidden details [OK]

Hint: Section views cut models to reveal inside parts [OK]

Common Mistakes:

• Thinking section views change model color
• Confusing section views with animations
• Assuming section views add textures

2. Which step is necessary to start creating a section view in SolidWorks?

easy

A. Add a dimension to the sketch

B. Apply a material texture to the model

C. Select a plane or face to define the cutting location

D. Export the model as a PDF

Solution

1. Step 1: Identify the first action for section view

   Creating a section view requires selecting a plane or face where the model will be cut.

2. Step 2: Eliminate unrelated steps

   Applying textures, exporting files, or adding sketch dimensions are not part of starting a section view.

3. Final Answer:

   Select a plane or face to define the cutting location -> Option C

4. Quick Check:

   Start section view = select cutting plane [OK]

Hint: Pick a plane first to cut the model [OK]

Common Mistakes:

• Trying to add textures before cutting
• Exporting instead of creating view
• Adding sketch dimensions unrelated to section

3. Given a model and a selected cutting plane, what will happen if you drag the section line further into the model in SolidWorks?

medium

A. More internal features will be revealed in the section view

B. The model color will change to red

C. The model will rotate automatically

D. The section view will close and disappear

Solution

1. Step 1: Understand the effect of moving the section line

   Dragging the section line deeper into the model cuts more material, revealing more internal features.

2. Step 2: Exclude unrelated effects

   Changing color, rotating, or closing the view are not caused by moving the section line.

3. Final Answer:

   More internal features will be revealed in the section view -> Option A

4. Quick Check:

   Drag section line = reveal more inside [OK]

Hint: Drag section line to see more inside [OK]

Common Mistakes:

• Expecting color changes from dragging
• Thinking model rotates automatically
• Assuming section view closes when dragged

4. You created a section view but it shows no internal details. What is the most likely mistake?

medium

A. The model color was set to transparent

B. The model was saved incorrectly

C. The section view was created in a different file

D. The cutting plane was placed outside the model

Solution

1. Step 1: Analyze why no internal details appear

   If the cutting plane is outside the model, the section view won't cut through anything, so no internal details show.

2. Step 2: Rule out unrelated causes

   Saving errors, file mix-ups, or color transparency do not prevent internal details from showing in a section view.

3. Final Answer:

   The cutting plane was placed outside the model -> Option D

4. Quick Check:

   No details = cutting plane outside model [OK]

Hint: Check cutting plane position if no details show [OK]

Common Mistakes:

• Assuming file or save errors cause no details
• Blaming color transparency for missing cut
• Not verifying cutting plane location

5. You need to create a section view that cuts through two different planes at once to show complex internal features. What is the best approach in SolidWorks?

hard

A. Use the standard view and hide external faces instead

B. Create a multi-section view by selecting multiple cutting planes

C. Create two separate section views and combine them manually

D. Export the model and edit it in another software

Solution

1. Step 1: Understand multi-section views

   SolidWorks allows creating section views with multiple cutting planes to show complex internal details in one view.

2. Step 2: Compare alternatives

   Creating separate views and combining manually is inefficient; hiding faces or exporting to other software is unnecessary and less clear.

3. Final Answer:

   Create a multi-section view by selecting multiple cutting planes -> Option B

4. Quick Check:

   Multi-section view = multiple planes cut at once [OK]

Hint: Use multi-section view for complex cuts [OK]

Common Mistakes:

• Trying to combine separate views manually
• Hiding faces instead of cutting
• Exporting model unnecessarily
