Learn how to create elliptical sketch profiles by defining two axes with the Ellipse tool.
What is the Ellipse tool?
You can use the Ellipse tool to create a closed sketch profile defined by two perpendicular axes. Ellipses can have different dimensions along each axis, while circles have a constant radius.
How to use the Ellipse tool
- Define your sketch plane.
- Go to Sketch > Ellipse.
For other ways to access tools, visit Accessing tools. - Define the ellipse using your input method:
- Keyboard and mouse/trackpad – Click to place the first point, move the pointer to define the first axis, and click to set its endpoint. Move the pointer perpendicular to the first axis and click to define the second axis.
- Touch and pen – Select a point on the grid for the center of the ellipse, then drag to position its circumference.
Tip
With a keyboard, you can enter values for the two axes before placing their endpoints.
History settings
Shapr3D records sketch items created on the same plane in a shared Sketch step in History. Find the Sketch step to review or modify these settings:
- Plane – Select Edit… or Select… to change the plane or face containing the sketch, then select Done.
- Projection – If applicable, select Edit… to modify existing projections in the sketch. To learn more, visit Project.
When to use the Ellipse tool
The Ellipse tool is useful for creating:
- Elliptical openings and cutouts – Sketch profiles for elongated holes or openings in a design.
- Oval-shaped parts – Create profiles for plates, covers, or other parts with elliptical outlines.
- Rounded design features – Define elongated curved profiles that can be extruded or used with other modeling tools.
- Layout references – Establish elliptical boundaries for positioning other sketch items.
Best practices and troubleshooting
- Choose the sketch plane before drawing to position the ellipse in the intended orientation.
- Use dimension values when you need precise axis lengths.
- Check the position of the first axis before defining the second axis.
| Issue | What to check |
|---|---|
| The ellipse is the wrong size. | Check the dimensions of both axes and adjust their values. |
| The ellipse is oriented incorrectly. | Check the direction of the first axis, which determines the ellipse's orientation. |
| The ellipse is not positioned where intended. | Check the placement of the ellipse and adjust its position in the sketch. |
