How Do I Change a Plane in a SolidWorks Assembly?

by

Changing a plane in a SolidWorks assembly is a fundamental skill that every user should know. Whether you need to reposition a plane or create a new one altogether, SolidWorks provides easy-to-use tools that make the process efficient and straightforward. In this tutorial, we will explore the different methods to change a plane in a SolidWorks assembly.

Method 1: Changing an Existing Plane

If you already have a plane in your assembly and want to modify its position or orientation, follow these steps:

  1. Select the Plane: In the FeatureManager Design Tree, locate the plane you want to change and click on it to select it.
  2. Edit the Plane: Right-click on the selected plane and choose “Edit Sketch” from the context menu.
  3. Modify the Sketch: The selected plane’s sketch will now be displayed. Make any necessary changes to its geometry using SolidWorks sketching tools.
  4. Exit Sketch Mode: Once you have made the desired modifications, click on “Exit Sketch” from the sketch toolbar or press Esc on your keyboard.

This method allows you to quickly edit an existing plane without recreating it from scratch. However, keep in mind that modifying an existing plane may affect other features or components dependent on it.

Method 2: Creating a New Plane

If you need to create a completely new plane in your assembly, SolidWorks offers several options:

A) Using Reference Geometry

  1. Select Reference Geometry: Go to the Features tab on the CommandManager and click on “Reference Geometry.”
  2. Create Plane: From the drop-down menu, select “Plane” to open the Plane PropertyManager.
  3. Define Plane Parameters: Specify the desired position and orientation of the new plane using available reference points, edges, or faces.
  4. Finish: Once you have defined all necessary parameters, click on “OK” to create the new plane.

B) Using 3D Sketching

  1. Select 3D Sketching: Go to the Sketch tab on the CommandManager and click on “3D Sketch.”
  2. Create Sketch Geometry: Use sketching tools to draw a series of lines or curves that define the desired plane’s shape and position.
  3. Exit Sketch Mode: Once you have completed defining the sketch geometry, click on “Exit Sketch” from the sketch toolbar or press Esc on your keyboard.

Note that creating a new plane gives you more flexibility in positioning it exactly where you need it. You can choose different methods based on your assembly requirements and design intent.

Tips for Efficient Plane Management

  • Use Meaningful Names: When creating or modifying planes, give them descriptive names that reflect their purpose in your assembly. This makes it easier to locate and manage them later.
  • Avoid Excessive Planes: While planes are useful for various design tasks, too many planes can clutter your assembly. Remove any unnecessary planes to keep your design clean and organized.

To summarize, changing a plane in a SolidWorks assembly is a straightforward process. Whether modifying an existing plane or creating a new one, SolidWorks provides intuitive tools to help you achieve your design goals efficiently. By using the methods outlined in this tutorial and implementing good management practices, you can effectively control and manipulate planes within your assemblies.
