CATIA V5 Tutorial #8 | O-Ring

In this step-by-step tutorial, we will be learning how to create an o-ring in CATIA V5. Some notable commands are Axis, Circle, 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:
O-Ring = 0.305763 in3

1. 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.
   
   
   
2. Click Sketch and select the xy plane.
   
   
   
   
   
3. Click Axis and create a horizontal axis line with a coincidence constraint to the HDirection.
   
   
   
   
   
4. Click Circle and move the cursor up coincident to the VDirection then click, move as required then click one last time to create the circle.
   
   
   
   
   
5. Click Constraint to apply a constraint to the sketch, apply and set the values (as shown).
   
   
   
   
   
6. Exit Workbench and click Shaft , set the parameters (as shown) and then click OK.
   
   
   
   
   
   
   
7. Completed!
