How to Create a Plane in SolidWorks: Step-by-Step Guide

In SolidWorks, you create a plane by selecting Reference Geometry > Plane and then defining its position using existing faces, edges, or points. You can create planes by offsetting from a face, setting an angle, or using three points to define the plane.

Syntax

To create a plane in SolidWorks, use the Plane tool found under Reference Geometry. You must select one or more references such as faces, edges, or points to define the plane's position and orientation.

• Offset Plane: Create a plane parallel to a face at a specified distance.
• Angle Plane: Create a plane at an angle to an edge or line.
• 3-Point Plane: Create a plane through three points or vertices.

Example

This example shows how to create an offset plane 10mm above a selected face:

arm_architecture

1. Open your part in SolidWorks.
2. Click on <code>Reference Geometry</code> in the Features toolbar.
3. Select <code>Plane</code>.
4. Click on the face you want to offset from.
5. Enter <code>10mm</code> in the offset distance box.
6. Click the green checkmark to create the plane.

Output

A new plane appears parallel to the selected face, 10mm above it.

Common Pitfalls

Common mistakes when creating planes include:

• Not selecting enough references to fully define the plane, causing errors.
• Choosing references that are not planar or ambiguous, leading to unexpected plane orientation.
• Forgetting to confirm the plane creation by clicking the green checkmark.

Always ensure your references clearly define the plane's position and orientation.

Wrong way:
- Select only one point without a face or edge.
- Try to create a plane without confirming.

Right way:
- Select a face and enter offset distance.
- Confirm by clicking the green checkmark.

Quick Reference

Plane Creation Method	Description	Required References
Offset Plane	Plane parallel to a face at a set distance	One face or plane
Angle Plane	Plane at an angle to an edge or line	One edge/line and one face/plane
3-Point Plane	Plane through three points or vertices	Three points or vertices
Midplane	Plane exactly between two parallel faces	Two parallel faces

Key Takeaways

Use Reference Geometry > Plane to start creating a plane in SolidWorks.

Select clear references like faces, edges, or points to define the plane.

Confirm your plane creation by clicking the green checkmark.

Use offset, angle, or 3-point methods depending on your design need.

Avoid ambiguous references to prevent errors in plane creation.
