Suppressing and unsuppressing features in Solidworks - Step-by-Step Guide

Introduction

Suppressing features temporarily hides them from your model without deleting them. This helps you focus on other parts or test changes. Unsuppressing brings the features back to the model.

When you want to test how your model looks without a specific feature like a hole or fillet

When your model is slow and you want to speed it up by hiding complex features temporarily

When you need to create different versions of a part by turning features on or off

When troubleshooting errors caused by a feature and you want to isolate the problem

When preparing a simplified model for presentations or analysis by hiding details

Steps

Step 1: Right-click the feature you want to suppress

- FeatureManager design tree

A menu appears with options related to the feature

Step 2: Click 'Suppress'

- Right-click menu

The feature icon in the tree turns gray and the feature disappears from the model view

💡 You can suppress multiple features by selecting them with Ctrl or Shift before right-clicking

Step 3: Right-click the suppressed feature (gray icon)

- FeatureManager design tree

The menu shows the option to unsuppress

Step 4: Click 'Unsuppress'

- Right-click menu

The feature icon returns to normal color and the feature reappears in the model

Step 5: Use the 'Suppress' and 'Unsuppress' buttons on the toolbar

- Features toolbar

Selected features are suppressed or unsuppressed without right-clicking

Before vs After

Before

FeatureManager design tree shows all features in normal color and the model displays all details

After

Suppressed features appear gray in the tree and are hidden from the model view

Settings Reference

Suppress

📍 Right-click menu on feature in FeatureManager design tree

Temporarily hide a feature from the model without deleting it

Default: Feature is unsuppressed by default

Multiple Feature Selection

📍 FeatureManager design tree

Allows suppressing or unsuppressing multiple features at once

Default: Single feature selection

Common Mistakes

Deleting a feature instead of suppressing it

Deleting removes the feature permanently and can break the model

Use suppress to hide the feature temporarily without losing it

Trying to suppress a feature that is required by others without unsuppressing dependencies

Suppressing dependent features can cause errors or broken references

Check feature dependencies and unsuppress required features before suppressing others

Summary

Suppressing hides features temporarily without deleting them

Unsuppressing brings features back to the model

Use suppress to test changes, speed up modeling, or create variations

Practice

1. What does suppressing a feature in SolidWorks do?
Suppress means:

easy

A. Permanently deletes the feature from the model

B. Locks the feature to prevent changes

C. Creates a copy of the feature

D. Temporarily hides the feature without deleting it

Solution

1. Step 1: Understand the meaning of suppress

   Suppressing a feature means hiding it temporarily so it does not affect the model but is not deleted.

2. Step 2: Compare options

   Only Temporarily hides the feature without deleting it describes hiding temporarily without deletion, which matches suppressing.

3. Final Answer:

   Temporarily hides the feature without deleting it -> Option D

4. Quick Check:

   Suppress = Temporary hide [OK]

Hint: Suppress means hide temporarily, not delete [OK]

Common Mistakes:

• Thinking suppress deletes the feature
• Confusing suppress with locking
• Assuming suppress duplicates the feature

2. Which of the following is the correct way to unsuppress a feature in SolidWorks?

easy

A. Right-click the feature and select Delete

B. Right-click the feature and select Unsuppress

C. Double-click the feature to hide it

D. Drag the feature out of the feature tree

Solution

1. Step 1: Identify the correct unsuppress action

   Unsuppressing means bringing back a hidden feature, done by right-clicking and choosing Unsuppress.

2. Step 2: Eliminate incorrect options

   Deleting removes the feature, double-click hides or edits, dragging out is invalid.

3. Final Answer:

   Right-click the feature and select Unsuppress -> Option B

4. Quick Check:

   Unsuppress = Right-click + Unsuppress [OK]

Hint: Unsuppress by right-clicking and choosing Unsuppress [OK]

Common Mistakes:

• Choosing Delete instead of Unsuppress
• Thinking double-click unsuppresses
• Trying to drag features to unsuppress

3. Given a model with three features: A (unsuppressed), B (suppressed), and C (unsuppressed). If you unsuppress feature B, what will be the visible features in the model?

medium

A. Features A, B, and C

B. Features A and C only

C. Only feature B

D. No features visible

Solution

1. Step 1: Understand current feature states

   Feature A and C are visible; B is hidden (suppressed).

2. Step 2: Unsuppress feature B

   Unsuppressing B makes it visible along with A and C.

3. Final Answer:

   Features A, B, and C -> Option A

4. Quick Check:

   Unsuppress B shows all three features [OK]

Hint: Unsuppress shows hidden features again [OK]

Common Mistakes:

• Assuming unsuppress hides other features
• Thinking only the unsuppressed feature shows
• Confusing suppress and unsuppress effects

4. You tried to unsuppress a feature but it remains hidden. What is the most likely cause?

medium

A. The feature is deleted, not suppressed

B. You did not save the model before unsuppressing

C. The feature is suppressed by a parent feature

D. The feature is locked and cannot be unsuppressed

Solution

1. Step 1: Analyze why unsuppress fails

   If a parent feature is suppressed, child features remain hidden even if unsuppressed.

2. Step 2: Check other options

   Deleted features cannot be unsuppressed; saving does not affect visibility; locking is not a standard feature.

3. Final Answer:

   The feature is suppressed by a parent feature -> Option C

4. Quick Check:

   Parent suppression blocks child unsuppress [OK]

Hint: Check parent feature suppression if unsuppress fails [OK]

Common Mistakes:

• Trying to unsuppress deleted features
• Assuming saving affects suppression
• Confusing locking with suppression

5. You have a complex assembly with multiple features suppressed to test a design change. After testing, you want to restore the original model quickly. What is the best practice to unsuppress all features efficiently?

hard

A. Use the Unsuppress All command in the feature tree

B. Unsuppress each feature one by one manually

C. Delete all suppressed features and recreate them

D. Restart SolidWorks to reset feature states

Solution

1. Step 1: Understand the need for efficiency

   Manually unsuppressing many features is slow and error-prone.

2. Step 2: Identify the best tool

   SolidWorks provides an Unsuppress All command to restore all suppressed features quickly.

3. Step 3: Eliminate wrong options

   Deleting features loses data; restarting does not change suppression; manual unsuppress is inefficient.

4. Final Answer:

   Use the Unsuppress All command in the feature tree -> Option A

5. Quick Check:

   Unsuppress All restores features fast [OK]

Hint: Use Unsuppress All to restore features fast [OK]

Common Mistakes:

• Unsuppressing features one by one
• Deleting suppressed features unnecessarily
• Restarting expecting suppression reset
