Introduction

Creating new planes in SolidWorks is a fundamental skill that enhances modeling flexibility and precision. For beginners, understanding when to create new planes can significantly streamline the design process. Whether you’re positioning features accurately or developing complex geometries, knowing the right times to add custom planes ensures your workflow is efficient and your models are precise. In this guide, we’ll explore practical scenarios, step-by-step instructions, and common pitfalls to help you confidently determine when beginners should create new planes in SolidWorks.

Why Creating New Planes Matters in SolidWorks

SolidWorks relies heavily on planes for sketching and feature placement. The default front, top, and right planes work for many cases, but often, complex designs demand custom reference planes. Creating new planes helps with:

• Precise feature placement at unusual angles or locations
• Building layered or multi-sided geometries
• Simplifying complex sketches by providing better references
• Ensuring easier modifications and feature updates

Knowing when to create new planes ensures your model is both accurate and manageable.

When Beginners Should Create New Planes in SolidWorks

1. To Insert Features at an Angle or Offset from Existing Geometry

When you need features (like holes, cuts, or extrusions) at an angle or a specific distance from existing components, a new plane provides a dedicated sketching surface.

• Example: Drilling holes at a 45-degree angle from the surface.
• Action: Create a plane offset or at an angle to set up your sketch precisely.

2. For Complex or Multi-Stage Modeling

Complex assemblies or parts often require multiple reference points. Creating new planes simplifies multi-step operations.

• Example: Building a multi-layer laminate or a series of features stacked at different heights.
• Action: Use new planes for each stage to keep sketches organized.

3. To Sketch in Places Where Default Planes Don’t Reach

Standard planes may not align with the geometry you want to work on.

• Example: Sketching on the inside surface of a curved part.
• Action: Create a tangent or offset plane that aligns properly with the geometry.

4. To Construct Symmetrical or Mirrored Features

Sometimes, creating a new plane as a mirror or symmetry plane simplifies the design process.

• Example: Mirroring features across a non-central axis.
• Action: Use a reference plane aligned with the feature for accurate symmetry.

5. To Simplify Complex Geometric Constructions

Certain features, especially those involving references at non-standard orientations, benefit from custom planes.

• Example: Drawing inclined or curved geometries.
• Action: Create inclined planes or axis planes that follow the form of your geometry.

6. For Advanced Design Techniques (e.g., Lofts and Sweeps)

Lofted or swept features often require multiple slicing planes to control the path and shape precisely.

• Example: Creating a tapered or twisted extrusion.
• Action: Generate multiple planes along the trajectory for greater control.

Step-by-Step Guide: Creating a New Plane in SolidWorks

To illustrate, here’s how beginners can create a new plane in a typical scenario where they need a plane 50 mm offset from a surface.

1. Select the initial reference geometry:

• Click on the surface or face where the plane will be based.

1. Access the Plane tool:

• Go to the Features tab.
• Click on “Reference Geometry” → “Plane.”

1. Set the plane parameters:

• Choose “Offset from Surface” or other options like “Angle” or “Parallel.”
• Enter the desired values (e.g., 50 mm offset).

1. Preview and confirm:

• Check the preview to ensure the plane is correctly positioned.
• Click OK to create the plane.

1. Use the new plane for sketching or features:

• Select the newly created plane and start sketching.

Practical Examples of When Beginners Should Create New Planes

Example 1: Creating an Angle Plane for a Bolt Hole

Suppose you’re designing a bracket that requires a bolt hole at a 30-degree angle to the main surface.

• Solution:
• Create a plane at 30 degrees using the “Plane Along edge” or “Angle” option.
• Sketch the hole on that plane, ensuring accurate placement.

Example 2: Building a Multi-Layer PCB Model

Designing a printed circuit board with multiple layers involves precise placement.

• Solution:
• Generate planes at specified offsets for each layer.
• Sketch and extrude copper traces on each plane independently.

Example 3: Sketching Inside a Curved Surface

Inside a tube or curved shell, sketching directly can be difficult.

• Solution:
• Create a tangent or offset plane along the surface.
• Use this plane as your sketching surface for internal features.

Common Mistakes to Avoid When Creating New Planes

• Creating redundant planes that can be achieved with offsets or existing geometry.
• Forgetting to name or organize planes, making later modifications difficult.
• Placing planes too close or intersecting with other geometry, causing confusion.
• Not updating or deleting unused planes, cluttering the feature tree.
• Relying excessively on default planes instead of custom ones where needed.

Best Practices for Creating and Managing Planes

• Name planes descriptively for easy identification.
• Use a consistent naming convention to track their purpose.
• Only create new planes when necessary to avoid clutter.
• Combine multiple reference features into a single plane (e.g., via mid-plane or offset) if possible.
• Regularly review and clean up unused planes.

Comparing Default and Custom Planes

Creating new planes offers precision and flexibility that default planes cannot, especially for advanced modeling tasks.

Conclusion

Knowing when beginners should create new planes in SolidWorks is crucial for efficient, accurate, and manageable CAD modeling. When features involve angles, offsets, internal sketches, or complex geometries, custom planes provide the necessary reference infrastructure. Practice identifying these opportunities early to enhance your design skills and streamline your workflow. Remember, well-organized planes not only improve your modeling accuracy but also make modifications easier down the line.

FAQ

1. When should I create a new plane instead of just sketching on the default planes?

Ans : Create a new plane when you need to sketch at an angle, offset, or in a location not accessible or practical with default planes.

2. How do I create an inclined plane in SolidWorks?

Ans : Use the “Plane” feature with the “Angle” option, selecting a reference face or edge, then set the desired angle.

3. Can I create multiple custom planes at once?

Ans : Yes, you can create multiple planes sequentially or use the “Plane” command with different parameters for each as needed.

4. Are there any best practices for managing many planes?

Ans : Yes, name planes clearly, organize them logically, and delete any unused or redundant planes regularly.

5. What is the difference between an offset plane and an angle plane?

Ans : An offset plane is parallel and set at a specific distance from a reference surface, while an angle plane is inclined at a specific angle relative to a reference feature.
