Create a plane through three points

Learn how to use the Plane Through Three Points tool to create a construction plane that passes through three vertices or snap points, or any mix of the two, in Fusion.

1. On the toolbar, select Construct > Plane Through Three Points .

   The Construction Geometry dialog displays, Type is set to Plane and Method is set to Through Three Points.

2. Select an Extent Type option to establish the end point of the plane.

3. In the canvas, select the first vertex or snap point.

4. Select the second vertex or snap point.

5. Select the third vertex or snap point.

6. Optional: Enter an Offset value to offset the plane from its computed position.

7. Optional: Set Resize:

   • Default: Size the plane to fit the selected geometry.
   • Extended: Size the plane to fill the current view.

8. Click OK.

The new construction plane displays in the canvas, passing through the three vertices or snap points you selected.

Tips

• The Offset value is saved with the feature. You can change the Offset value later using Edit Feature.
• Create construction planes when you want to create sketches that do not lie on one of the 3 default planes.
• Use construction planes as the input for other tools, like the cutting tool for the Split Body tool.
• Use a Plane Through Three Points when you want to create a connecting body between existing bodies.
• Snap points help on complex or periodic faces where vertex-only picks are limiting.
• To change any of the three locations after you create the feature, select it in the timeline or browser and use Edit Feature.
• To show or hide plane name labels on the canvas, see Show or hide plane names on the canvas.
