Creating a sphere in SOLIDWORKS can be achieved using a single sketch and a single feature. This post runs through the options for creating a sphere, the rules to follow and the steps required.

Spheres can be created in SOLIDWORKS as solid or surface geometry. Both results require a sketch and either a Revolve Boss/Base feature or a Revolved Surface feature. Creating a sphere using the Revolve Boss/Base feature will result in solid geometry that has a mass. Creating a sphere using the Revolved Surface feature will result in surface geometry which is infinitely thin and has no mass.

More information on creating revolves can be seen here.

Creating a Solid Sphere

 

To create a solid sphere in SOLIDWORKS, use the Revolve Boss/Base feature. The steps are described below and are also demonstrated in the video above.

  1. Create a new sketch
  2. Draw a circle with a line intersecting it directly through the centre point
  3. Trim one side of the circle away, leaving the central sketch line as solid
  4. Create a Revolve Boss/Base
  5. Direction Angle should be set to 360°
  6. Accept the feature

Creating a Surface Sphere

 

To create a surface sphere in SOLIDWORKS, use the Revolved Surface feature. The steps are described below and are also demonstrated in the video above.

  1. Create a new sketch
  2. Draw a circle with a line intersecting it directly through the centre point
  3. Trim one side of the circle away, make the central sketch line construction
  4. Create a Revolved Surface
  5. Direction Angle should be set to 360°
  6. Accept the feature

Extra Tip

The Surface menu on the command manager does not appear by default when SOLIDWORKS is first installed. To access the Surface menu, R>Click on one of the existing tabs on the Command Manager and tick on Surfaces.
