Animation basics in Solidworks - Step-by-Step Guide

Introduction

Animation basics in SolidWorks help you show how parts move or fit together. This makes it easier to explain designs and check if everything works well.

When you want to show how a machine part moves step-by-step.

When you need to explain assembly instructions clearly to a team.

When you want to check if parts collide or fit during movement.

When you want to create a presentation to show your design in action.

When you want to simulate how a product works before building it.

Steps

Step 1: Open your assembly file

- SolidWorks main window

Your assembly model appears on screen

Step 2: Click the Motion Study tab

- Bottom left of the SolidWorks window

The Motion Study timeline and controls appear below the model

Step 3: Select Animation from the Motion Study type dropdown

- Motion Study toolbar

The timeline is set for animation mode

Step 4: Drag the timeline cursor to the desired time

- Motion Study timeline

The time indicator moves to the chosen point

Step 5: Move or rotate parts in the assembly

- Graphics area

Parts move to new positions at the selected time on the timeline

Step 6: Add keyframes by clicking the 'Calculate' or 'Add Key' button

- Motion Study toolbar

SolidWorks records the part positions at that time

Step 7: Click Play to preview the animation

- Motion Study controls

The assembly moves smoothly between keyframes showing the animation

Before vs After

Before

Assembly parts are static and all in starting positions at time 0

After

Parts move and rotate smoothly over time showing how the assembly works

Settings Reference

Motion Study Type

📍 Motion Study toolbar dropdown

Choose the type of motion simulation you want to create

Default: Animation

Timeline Cursor

📍 Motion Study timeline

Select the time point to set part positions or keyframes

Default: Start at 0 seconds

Keyframe

📍 Motion Study toolbar

Record part positions at specific times to create animation steps

Default: No keyframes at start

Common Mistakes

Not adding keyframes after moving parts

Without keyframes, SolidWorks does not record the movement and animation won't play

Always add a keyframe after moving or rotating parts at a timeline position

Using Basic Motion or Motion Analysis mode when only simple animation is needed

These modes require more setup and can slow down the process for simple animations

Use Animation mode for basic part movement and visual explanations

Summary

Animation basics let you show how parts move in your assembly over time.

Use the Motion Study tab to create and control animations with keyframes.

Remember to add keyframes after moving parts to record their positions.

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
