Click on the sketch and select the eyeball icon to make it visible. On the Features tab, select Reference Geometry and click on Plane. For the First Reference, you can drop down the design tree in the top left of your workspace and select the Right Plane. Set the offset distance to 24mm and click the green checkmark when you are finished. − − [[File:Egg 17.png|1500px|none]] − <br> − <br> − <strong>Step 18:</strong> In the design tree, right click on the plane and select the sketch icon. Draw a circle on the plane and make its center point coincident with the point on the side of your egg as shown in the screenshot below. To make these two points coincident, hold shift and click on both the center point of the circle and the point on the side of the egg. Then use the Add Relations section to make them coincident. Use the Smart Dimension tool to set the diameter of the circle to 2mm (radius of 1mm). − − [[File:Egg 18.png|1500px|none]] − <br> − <br> − <strong>Step 19:</strong> Exit the sketch and start a new sketch by right clicking the top plane and selecting the sketch icon. Draw a circle on the top plane and use the Smart Dimension tool to set the following parameters. Set the diameter of the circle to 10mm. Set the distance from the origin to the center of the circle as 35mm. Add a horizontal relation between the center of the circle and the origin by holding shift, clicking both points, and selecting the appropriate relation. Double-check to make sure everything is fully defined. − − [[File:Egg 19.png|1500px|none]] − <br> − <br> − <strong>Step 20:</strong> On the Features tab, select the Lofted Boss/Base option. For the Profiles, select the two circles that you drew in the previous two steps. Manipulate the green dots to shape the profile and try to avoid creating an intersecting geometry, which will give you an error. Click the green checkmark when you are finished. − − [[File:Egg 20.1.png|1500px|none]] − [[File:Egg 20.2.png|1500px|none]] − <br> − <br> − <strong>Step 21:</strong> With the loft selected, go to the Features tab and drop down the arrow underneath the Linear Pattern button. Select Circular Pattern. Click on the 72mm line to choose the pattern axis. Select the Equal spacing option and increase the number of instances to the desired amount. 6 supports is probably fine. − − [[File:Egg 21.png|1500px|none]] − <br> − <br> − <strong>Step 22:</strong> You should now have something that looks like an egg spaceship.

<strong>Step 16:</strong> You should now have a 3D egg similar to the screenshot below. However, this design is not ready for 3D printing. You can click and hold the scroll wheel to rotate the egg, and you'll notice that the 6mm line at the bottom of the egg has now turned into a 12mm diameter circle. We have intentionally made this flat spot a little larger to get better adhesion to the base plate during the print, but it is not sufficient on its own to keep the egg from tipping over in the event that the nozzle crashes into it. Later on, we will add supports to the bottom part of the egg using the PrusaSlicer software that will support the shallow parts of the egg's curvature. But for now, we are going to add structural supports in SolidWorks that will mitigate the risk of the egg tipping over in the middle of the print.
