In this step-by-step tutorial, we will be learning how to create a sphere in CATIA V5. Some notable commands are Axis, Arc, Constraint, and Shaft. The Part Design and Sketcher Workbenches will be used to create the 3D CAD model. A 2D engineering drawing and video is included at the end of this blog post, you can also check your model by comparing the part volume.
Level = Beginner
Quick Notes = All dimensions are in inches.
Part Volume:
Sphere = 65.449848 in3
- Start by creating a new CATPart.
Click File > New…
> Select Part in the dialog box and click OK. Confirm that the Part Design 
Workbench is active. - Click Sketch
and select the yz plane.
- Click Axis
and create a vertical axis line with a coincidence constraint to the VDirection.
- Click Arc
and select the sketch origin point. Move the cursor up coincident to the axis line then click to start the arc, move the cursor down coincident to the axis line then click one last time to create the arc.
- Click Line
to create a line to connect the arc points.
- Click Constraint
to apply a constraint to the sketch, apply and set the value (as shown).
- Exit Workbench
and click Shaft 
, set the parameters (as shown) and then click OK.
- Completed!
Perfect sphere tutorial, thank you.
