Animation basics in Solidworks - Real Business Scenario

Scenario Mode

👤 Your Role: You are a product designer using SolidWorks

📋 Request: Your manager wants a simple animation showing how a new mechanical part moves during operation

📊 Data: You have a 3D model of the mechanical part with all components assembled

🎯 Deliverable: Create a basic animation in SolidWorks that demonstrates the part's movement step-by-step

Sample Data

Component	Movement Type	Start Position	End Position	Duration (seconds)
Lever Arm	Rotation	0°	45°	3
Slider	Linear	0 mm	20 mm	2
Spring	Compression	0 mm	5 mm	2
Latch	Rotation	0°	30°	1.5

1

Step 1: Open the SolidWorks assembly file containing the mechanical part

File > Open > Select assembly file

Expected Result

Assembly model loads in SolidWorks workspace

2

Step 2: Switch to the Motion Study tab at the bottom of the screen

Click on 'Motion Study 1' tab

Expected Result

Motion Study interface appears with timeline and animation controls

3

Step 3: Add a rotation motor to the Lever Arm component

Insert > Motor > Select Lever Arm > Set rotation from 0° to 45° over 3 seconds

Expected Result

Rotation motor appears on timeline controlling Lever Arm rotation

4

Step 4: Add a linear motor to the Slider component

Insert > Motor > Select Slider > Set linear movement from 0 mm to 20 mm over 2 seconds

Expected Result

Linear motor appears on timeline controlling Slider movement

5

Step 5: Add a compression motor to the Spring component

Insert > Motor > Select Spring > Set compression from 0 mm to 5 mm over 2 seconds

Expected Result

Compression motor appears on timeline controlling Spring compression

6

Step 6: Add a rotation motor to the Latch component

Insert > Motor > Select Latch > Set rotation from 0° to 30° over 1.5 seconds

Expected Result

Rotation motor appears on timeline controlling Latch rotation

7

Step 7: Arrange the motors on the timeline sequentially to show step-by-step movement

Drag motors on timeline so Lever Arm rotates first, then Slider and Spring move together, then Latch rotates last

Expected Result

Timeline shows motors in sequence: Lever Arm (0-3s), Slider & Spring (3-5s), Latch (5-6.5s)

8

Step 8: Play the animation to preview the part movement

Click Play button in Motion Study tab

Expected Result

Animation plays showing the mechanical part moving as per the timeline

9

Step 9: Save the animation as a video file

Save Animation > Choose video format (e.g., MP4) > Save

Expected Result

Video file of the animation is saved for sharing

Final Result

Mechanical Part Animation Timeline

| Lever Arm Rotation (0° to 45°) |----3s----|
| Slider & Spring Movement (0 to 20mm & 0 to 5mm) |----2s----|
| Latch Rotation (0° to 30°) |--1.5s--|

[Play Animation] --> Shows smooth step-by-step movement of parts

✓The animation clearly shows the sequence of mechanical movements

✓Lever Arm rotates first, followed by Slider and Spring moving together

✓Latch rotates last to complete the operation cycle

✓This animation helps visualize the part function for stakeholders

Bonus Challenge

Add camera movements to the animation to zoom in on key parts during their motion

Show Hint

Use the 'Camera' tool in Motion Study to create keyframes for zoom and pan effects

Practice

1. What is the main purpose of animation in SolidWorks?
Animation helps to:

easy

A. Create static 2D drawings

B. Calculate part weight automatically

C. Show how parts move or fit together over time

D. Generate manufacturing cost reports

Solution

1. Step 1: Understand animation purpose

   Animation in SolidWorks is used to demonstrate movement or assembly of parts over time.

2. Step 2: Eliminate unrelated options

   Options about static drawings, weight calculation, or cost reports do not relate to animation.

3. Final Answer:

   Show how parts move or fit together over time -> Option C

4. Quick Check:

   Animation = Show movement [OK]

Hint: Animation = parts moving or assembling over time [OK]

Common Mistakes:

• Confusing animation with static drawing creation
• Thinking animation calculates physical properties
• Assuming animation generates reports

2. Which of the following is the correct way to add a keyframe in SolidWorks animation?

easy

A. Use the 'Export Animation' button

B. Right-click timeline and select 'Add Key Point'

C. Drag parts directly without timeline interaction

D. Click the timeline at desired time and press 'Add Keyframe'

Solution

1. Step 1: Recall keyframe addition method

   In SolidWorks animation, you add keyframes by clicking the timeline at the desired time and selecting 'Add Keyframe'.

2. Step 2: Identify incorrect options

   Options about 'Add Key Point' or dragging parts without timeline are incorrect. Exporting animation is unrelated.

3. Final Answer:

   Click the timeline at desired time and press 'Add Keyframe' -> Option D

4. Quick Check:

   Add keyframe = timeline click + add [OK]

Hint: Add keyframe by clicking timeline at time [OK]

Common Mistakes:

• Confusing 'Add Key Point' with 'Add Keyframe'
• Trying to add keyframe without timeline
• Using export button to add keyframes

3. Given an animation timeline with keyframes at 0s (position A) and 5s (position B), what happens if you preview the animation at 3s?

medium

A. The part is at position A

B. The part is between position A and B

C. The animation shows an error

D. The part is at position B

Solution

1. Step 1: Understand keyframe interpolation

   Between keyframes, SolidWorks animates parts moving smoothly from one position to another.

2. Step 2: Apply to 3s preview

   At 3 seconds, which is between 0s and 5s, the part will be in a position between A and B.

3. Final Answer:

   The part is between position A and B -> Option B

4. Quick Check:

   Between keyframes = smooth transition [OK]

Hint: Preview between keyframes shows in-between position [OK]

Common Mistakes:

• Assuming part stays at first keyframe until next
• Thinking part jumps instantly to next keyframe
• Expecting error without reason

4. You created an animation but the part does not move when previewing. What is the most likely cause?

medium

A. No keyframes were added to the timeline

B. The part is hidden in the assembly

C. The animation was exported instead of previewed

D. The timeline is set to loop

Solution

1. Step 1: Check keyframe presence

   If no keyframes exist, SolidWorks has no instructions to move the part.

2. Step 2: Evaluate other options

   Hidden parts still can be animated if keyframes exist; exporting does not affect preview; looping affects repetition, not movement.

3. Final Answer:

   No keyframes were added to the timeline -> Option A

4. Quick Check:

   No keyframes = no movement [OK]

Hint: No keyframes means no animation movement [OK]

Common Mistakes:

• Ignoring missing keyframes
• Confusing export with preview
• Thinking loop disables movement

5. You want to create an animation showing a part rotating 90 degrees over 4 seconds and then moving 10 cm forward over 3 seconds. How should you set the keyframes?

hard

A. Add a rotation keyframe at 0s and 4s, then a translation keyframe at 4s and 7s

B. Add rotation and translation keyframes both at 0s and 7s only

C. Add translation keyframes at 0s and 3s, then rotation keyframes at 3s and 7s

D. Add a single keyframe at 7s with both rotation and translation

Solution

1. Step 1: Plan rotation timing

   Rotation happens over first 4 seconds, so keyframes at 0s (start) and 4s (end rotation).

2. Step 2: Plan translation timing

   Translation starts after rotation, from 4s to 7s, so keyframes at 4s (start move) and 7s (end move).

3. Step 3: Combine keyframes correctly

   Set rotation keyframes first, then translation keyframes sequentially to show smooth animation.

4. Final Answer:

   Add a rotation keyframe at 0s and 4s, then a translation keyframe at 4s and 7s -> Option A

5. Quick Check:

   Sequential keyframes = smooth staged animation [OK]

Hint: Set keyframes sequentially for each motion phase [OK]

Common Mistakes:

• Overlapping keyframes causing simultaneous moves
• Missing intermediate keyframes
• Using single keyframe for multiple motions
