How Do You Make a Motion in SolidWorks?

Creating motion in SolidWorks allows you to bring your designs to life, giving them the ability to move and interact. Whether you want to simulate the motion of a simple mechanism or create complex animations, SolidWorks offers a range of tools and features to help you achieve your desired results.

Setting Up the Environment

Before we dive into creating motion, let’s make sure we have everything set up correctly. First, open your assembly file in SolidWorks. If you don’t have one already, create a new assembly by going to File > New > Assembly.

To enable motion studies, go to the Motion Study tab on the left-hand side of the screen. If you don’t see this tab, right-click on any existing tab and select Motion Study from the list.

Defining Constraints

In order for your components to move correctly, you need to define constraints that mimic real-world connections. To do this, go to the Motion Study tab and click on Add Motion. This will bring up a toolbar with various types of constraints you can apply.

For example, if you want two components to be connected with a revolute joint (allowing rotation), select the Revolute Joint option from the toolbar. Then, click on one component and then on another component to create the joint.

TIP:

  • Selecting multiple components: To select multiple components at once, hold down the Ctrl key while clicking on each component.
  • Different types of constraints: Besides revolute joints, SolidWorks also offers other types of constraints such as cylindrical, prismatic, and planar. Experiment with these options to achieve the desired motion.

Creating Keyframes

Now that you have defined constraints, it’s time to create keyframes to specify the position and orientation of your components at different points in time. Keyframes are like snapshots that represent specific moments in your animation.

To create a keyframe, move the time slider (located at the bottom of the screen) to the desired frame. Then, select a component and use the Move Component tool (found in the Motion Study tab) to position or rotate it as needed.

Continue moving the time slider and adjusting components until you have created keyframes for all important moments in your animation.

TIP:

  • Copying keyframes: If there are similar movements that repeat throughout your animation, you can save time by copying keyframes. Simply select a keyframe, right-click on it, and choose Copy Keyframe.

    Then, move the time slider to another frame and right-click again to paste the copied keyframe.

  • Interpolation: SolidWorks automatically interpolates between keyframes to create smooth motion. However, if you want more control over how components move between keyframes, you can adjust interpolation settings by right-clicking on a keyframe and selecting Edit Keyframe Properties.

Analyzing Motion

SolidWorks provides tools for analyzing motion within your assembly. This can help identify any interference or collisions between components during movement.

To analyze motion, go to the Motion Study tab and click on Analyze. SolidWorks will simulate the motion based on your defined constraints and keyframes.

If any interference is detected, components will turn red, indicating a collision. You can then go back and adjust your constraints or keyframes to resolve the issue.

Rendering and Exporting Your Animation

Once you are satisfied with your motion study, it’s time to render and export your animation. SolidWorks offers various output options, including video formats such as AVI and MP4.

To render your animation, go to the Motion Study tab and click on Render Animation. This will bring up rendering settings where you can specify the image quality, frame rate, and output format.

After specifying your desired settings, click on Render to start the rendering process. Once complete, you can save your animation by going to File > Save As.

TIP:

  • Adjusting camera views: To create more dynamic animations, experiment with different camera views. Use the Fly or Walk Through tools (found in the Motion Study tab) to navigate through your assembly and set up interesting perspectives.
  • Additional effects: If you want to add special effects or annotations to your animation, SolidWorks provides tools for that as well. Explore the various options available in the Motion Study tab to enhance your final result.

Congratulations! You have now learned how to create motion in SolidWorks. With the right constraints, keyframes, and analysis tools, you can bring your designs to life and showcase their functionality.

Remember to experiment and have fun with different motion concepts. The more you practice, the more proficient you will become at creating captivating animations in SolidWorks.
