Suppressing and unsuppressing features in Solidworks - Real Business Scenario

Scenario Mode

👤 Your Role: You are a product design analyst at a manufacturing company.

📋 Request: Your manager wants you to analyze how suppressing and unsuppressing features in SolidWorks affects the final product design and assembly.

📊 Data: You have access to a SolidWorks assembly file with multiple parts and features. Each feature can be suppressed or unsuppressed to test different design options.

🎯 Deliverable: Create a report showing which features are suppressed or unsuppressed in different design scenarios and how this impacts the assembly structure and part count.

Sample Data

Feature Name	Status	Part Count	Assembly Impact
Base Extrude	Unsuppressed	1	Included
Cut Hole	Suppressed	0	Excluded
Fillet Edge	Unsuppressed	1	Included
Boss Extrude	Suppressed	0	Excluded
Chamfer	Unsuppressed	1	Included
Pattern Feature	Unsuppressed	4	Included
Mirror Feature	Suppressed	0	Excluded

1

Step 1: Open the SolidWorks assembly file and list all features with their current suppression status.

Use the FeatureManager Design Tree to identify each feature and note if it is suppressed or unsuppressed.

Expected Result

A list of features with their suppression status as shown in the sample data.

2

Step 2: Create a table summarizing the number of parts affected by each feature based on its suppression status.

Count parts included when feature is unsuppressed; count zero when suppressed.

Expected Result

Table with Part Count column showing 1 or more for unsuppressed features and 0 for suppressed features.

3

Step 3: Analyze the assembly impact by checking which features contribute to the final assembly structure.

Mark features as 'Included' if unsuppressed, 'Excluded' if suppressed.

Expected Result

Assembly Impact column showing 'Included' or 'Excluded' accordingly.

4

Step 4: Create a report or dashboard visualizing feature suppression status and its effect on part count and assembly inclusion.

Use a bar chart with features on X-axis, part count on Y-axis, color-coded by suppression status.

Expected Result

A clear visual showing which features are suppressed and how many parts they affect.

5

Step 5: Interpret the results to advise on design options by suppressing or unsuppressing features.

Summarize key findings from the table and chart.

Expected Result

Insight that suppressing features reduces part count and assembly complexity, useful for design optimization.

Final Result

Feature Suppression Report

Feature Name   | Status      | Part Count | Assembly Impact
---------------------------------------------------------
Base Extrude   | Unsuppressed| 1          | Included
Cut Hole      | Suppressed  | 0          | Excluded
Fillet Edge   | Unsuppressed| 1          | Included
Boss Extrude  | Suppressed  | 0          | Excluded
Chamfer       | Unsuppressed| 1          | Included
Pattern Feature| Unsuppressed| 4          | Included
Mirror Feature| Suppressed  | 0          | Excluded

✓Unsuppressed features contribute parts to the assembly and are included in the final design.

✓Suppressed features do not add parts and are excluded from the assembly, simplifying the design.

✓Pattern Feature adds the most parts (4) when unsuppressed, significantly impacting assembly complexity.

✓Suppressing features can optimize the design by reducing part count and assembly size.

Bonus Challenge

Create multiple design scenarios by selectively suppressing and unsuppressing features, then compare their assembly impacts side-by-side.

Show Hint

Use configuration management in SolidWorks to save different suppression states and export data for comparison.

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
