How To Create Plane In SolidWorks: Comprehensive Step-by-Step Guide
Reference geometry features like planes are fundamental for building complex parametric models in SolidWorks, serving as sketching surfaces and mating anchors when standard default planes are insufficient. Mastering standard, offset, angle, and line-normal plane creation methods ensures parametric stability and eliminates rebuild errors during downstream assembly and feature modifications.
Pre-Operation & Planning for SolidWorks Reference Geometry
Proper model tree architecture and design intent rely heavily on utilizing reference geometry efficiently. Before adding arbitrary planes, examine whether existing model faces, default planes (Front, Top, Right), or coordinate systems can satisfy the design requirement, thereby keeping the FeatureManager design tree lightweight and performant.
- Essential Software and Hardware: SolidWorks 2021 or newer installed on a workstation meeting SOLIDWORKS hardware certification guidelines, equipped with a three-button mouse.
- Mandatory Prerequisite Knowledge: Familiarity with 2D sketching, parametric relations, feature-based modeling, and the active coordinate system of the active part file.
- Estimated Setup Duration: 2 to 5 minutes per plane configuration, depending on model complexity and reference selection.
Step-by-Step Procedure to Construct Planes in SolidWorks
Step 1: Access the Reference Geometry Tool
Open your part document in SolidWorks. Navigate to the CommandManager ribbon and select the Features tab. Locate the Reference Geometry flyout menu, which typically sits near the top right of the toolbar panel, and click on Plane to open the Plane PropertyManager panel on the left side of your screen.
Pro-Tip: You can assign a custom keyboard shortcut, such as the letter P, to the Plane command via Tools > Customize to accelerate your modeling workflow.
Step 2: Define First, Second, and Third References
In the Plane PropertyManager, look at the First Reference selection box. Click on a model face, an existing plane, an axis, or a vertex in your graphics area to establish the foundational constraint for your new plane. Select subsequent references (Second and Third References) if required by your chosen geometry type, such as defining an angle or making a plane pass through three distinct points.
Step 3: Set Constraints and Offset Distances
Once your references are registered in the PropertyManager, SolidWorks will display a real-time preview of the plane. If you selected an offset method, type the desired numerical distance into the Offset Distance spin box. Alternatively, adjust the angle parameter if you are creating an inclined plane relative to a reference face or plane.
Warning: Avoid referencing dynamic or draft-heavy geometry that may change drastically in future design iterations, as this frequently causes broken parent-child dependencies and missing-reference rebuild errors.
Step 4: Manage Plane Count and Confirm Feature
If you need multiple parallel planes spaced evenly, locate the Options section in the PropertyManager and input a value greater than one in the Number of Planes to Create field. Verify that the preview aligns with your engineering intent, then click the green checkmark (OK) in the upper right corner of the graphics area or PropertyManager to commit the feature.

SolidWorks Reference Plane Types and Parametric Behavior
| Plane Type | Primary Reference Requirement | Typical Engineering Application | Common Failure Mode |
|---|---|---|---|
| Offset Plane | Single planar face or default plane | Creating parallel cut-extrusions at specific depths | Referencing a face that gets suppressed or deleted |
| Angle Plane | Cylindrical face and a planar face/axis | Rib placement or draft-angle feature creation | Axis misalignment due to circular geometry edits |
| Through Line/Point | One linear edge and one vertex/point | Swept path orientation or complex loft profiles | Point and line non-coplanar mismatch |
| MidPlane | Two parallel faces or default planes | Symmetric features, mirror operations, and assemblies | Selecting non-parallel faces causing invalid math |
Troubleshooting Common SolidWorks Plane Errors
- Error: Reference entity is deleted or missing
- Root Cause: A model modification removed the underlying face, edge, or vertex that the plane was parented to, breaking the parametric chain.
- Actionable Fix: Right-click the missing plane in the FeatureManager design tree, select Edit Feature, and re-select a stable, permanent geometry reference in the graphics window.
- Error: The plane is invalid or cannot be created with the selected references
- Root Cause: Conflicting geometric constraints, such as parallel references selected for an angle constraint or non-intersecting lines.
- Actionable Fix: Clear the reference selection boxes in the PropertyManager by right-clicking them, then re-apply references that follow proper geometric rules (e.g., combining a line and a point).
- Error: Rebuild errors downstream in the FeatureManager tree
- Root Cause: Subsequent features like extrudes, cuts, or patterns rely on the newly modified plane, and a shift in plane orientation invalidates their sketch geometry.
- Actionable Fix: Use the Rollback Bar to step backward before the failing feature, inspect the parent-child dependencies via the Right-Click menu, and correct the sketch relations on the plane.
Frequently Asked Questions
How do I make a plane at an angle in SolidWorks?
Open the Plane PropertyManager via Features > Reference Geometry > Plane. Select a cylindrical face or linear axis as your first reference, and then select a flat face or default plane as your second reference to activate the angle input box, where you can type your exact degree measurement.
Can I resize or move a plane in SolidWorks?
Yes, you can click and drag the white circular corner handles or edge nodes of the plane wireframe in the graphics area to visually resize its display boundary for better visibility. To move its location precisely, edit the feature and modify the offset distance or select new reference geometry.
What is the shortcut to create a plane quickly?
While there is no default single-key shortcut assigned out-of-the-box, you can hold down the Ctrl key while left-clicking and dragging an existing default plane or planar face into the graphics area to instantly launch the Plane PropertyManager with a pre-set offset distance.
Why is my plane option grayed out in SolidWorks?
The plane command often appears grayed out if you are actively inside an open sketch or editing a component context in an assembly without proper modification rights. Close the active sketch by clicking the sketch icon in the top right corner of the screen to restore access to reference geometry features.
