Interactivity

A filter for Design ID allows selecting one or multiple designs. When applied, all components update to show data only for the selected designs. For example, selecting D002 and D004 updates KPIs, charts, and table to reflect only those designs.

Hovering over bars or scatter points shows tooltips with exact values for better understanding.

Self Check

If you add a filter to show only designs with Mirror Features greater than 3, which components update?

• Average Mirror Features KPI updates to average of filtered designs.
• Average Design Time KPI updates accordingly.
• Bar Chart shows only designs with Mirror Features > 3.
• Scatter Plot shows points only for filtered designs.
• Table shows only rows matching the filter.

Key Result

Dashboard analyzing SolidWorks Mirror feature usage across designs, showing averages, counts, and relationships with errors and design time.

Practice

1. What is the primary purpose of the Mirror feature in SolidWorks?

easy

A. To scale a part uniformly

B. To create a symmetrical copy of a part or feature

C. To rotate a part around an axis

D. To delete unwanted features

Solution

1. Step 1: Understand the Mirror feature function

   The Mirror feature is used to create a copy of a part or feature that is symmetrical about a plane or face.

2. Step 2: Compare options with the Mirror feature purpose

   Only To create a symmetrical copy of a part or feature describes creating a symmetrical copy, which matches the Mirror feature's purpose.

3. Final Answer:

   To create a symmetrical copy of a part or feature -> Option B

4. Quick Check:

   Mirror feature = symmetrical copy [OK]

Hint: Mirror copies symmetrically about a plane or face [OK]

Common Mistakes:

• Confusing Mirror with Rotate or Scale
• Thinking Mirror deletes features
• Assuming Mirror changes size

2. Which of the following is the correct first step when creating a Mirror feature in SolidWorks?

easy

A. Select the mirror plane or face

B. Select the feature to mirror

C. Create a new sketch

D. Save the file

Solution

1. Step 1: Identify the mirror reference

   To create a Mirror feature, you must first select the plane or face about which the feature will be mirrored.

2. Step 2: Confirm the correct order of selection

   After selecting the mirror plane or face, you then select the feature to mirror. So the first step is selecting the mirror plane or face.

3. Final Answer:

   Select the mirror plane or face -> Option A

4. Quick Check:

   First step = select mirror plane [OK]

Hint: Always pick mirror plane before features [OK]

Common Mistakes:

• Selecting features before mirror plane
• Starting with a new sketch unnecessarily
• Saving before creating the mirror

3. Given a part with a single extruded boss feature on the right side, what will happen if you apply a Mirror feature about the center plane of the part?

medium

A. A symmetrical extruded boss will appear on the left side

B. The original feature will be deleted

C. The part will be scaled down by half

D. Nothing will change

Solution

1. Step 1: Understand the Mirror feature effect on a single feature

   Mirroring about the center plane creates a symmetrical copy on the opposite side of the plane.

2. Step 2: Apply this to the extruded boss on the right side

   The extruded boss on the right will be copied symmetrically to the left side, creating a matching feature.

3. Final Answer:

   A symmetrical extruded boss will appear on the left side -> Option A

4. Quick Check:

   Mirror about center plane = symmetrical copy opposite side [OK]

Hint: Mirror duplicates features symmetrically [OK]

Common Mistakes:

• Thinking Mirror deletes original features
• Assuming Mirror scales the part
• Believing Mirror does nothing without multiple features

4. You tried to create a Mirror feature but received an error saying "No valid entities selected to mirror." What is the most likely cause?

medium

A. You selected the wrong file format

B. You selected multiple mirror planes

C. You forgot to save the part before mirroring

D. You did not select any features or bodies to mirror

Solution

1. Step 1: Analyze the error message

   The error "No valid entities selected to mirror" means the software did not detect any features or bodies chosen for mirroring.

2. Step 2: Identify the common cause

   This usually happens when the user selects the mirror plane but forgets to select the features or bodies to mirror.

3. Final Answer:

   You did not select any features or bodies to mirror -> Option D

4. Quick Check:

   Error means no features selected [OK]

Hint: Always select features after mirror plane [OK]

Common Mistakes:

• Ignoring the need to select features
• Confusing error with file or save issues
• Selecting multiple mirror planes incorrectly

5. You have a complex part with multiple features on one side. You want to mirror all these features about a mid-plane but exclude one small feature. What is the best approach?

hard

A. Use the Mirror feature on the small feature only

B. Mirror the entire part and then delete the small feature on the mirrored side

C. Select all features except the small one before applying the Mirror feature

D. Create a new sketch excluding the small feature and mirror that sketch

Solution

1. Step 1: Understand selective mirroring

   The Mirror feature allows selecting specific features to mirror, so you can exclude unwanted ones by not selecting them.

2. Step 2: Compare options for excluding a feature

   Select all features except the small one before applying the Mirror feature directly excludes the small feature by not selecting it, which is efficient and clean. Mirror the entire part and then delete the small feature on the mirrored side wastes effort deleting after mirroring. Create a new sketch excluding the small feature and mirror that sketch is complex and unnecessary. Use the Mirror feature on the small feature only mirrors only the small feature, which is opposite of the goal.

3. Final Answer:

   Select all features except the small one before applying the Mirror feature -> Option C

4. Quick Check:

   Exclude by selection before mirroring [OK]

Hint: Pick only features you want mirrored [OK]

Common Mistakes:

• Mirroring everything then deleting
• Trying to mirror sketches instead of features
• Mirroring only the unwanted feature
