Cinema 4D - Activity 1 Holes

 Firstly I got a cogwheel out of the free hand spline tool and then got a circle and scaled it so that the circle was smaller than the cogwheel. I then made the spline editable by going on the object menu.


I then created a extrude NURBS object, and dropped in both  splines to get an extrude of that shape. I then connected the two spline and dropped the new connected outlines to the Nurbs object . It then makes a hole.

This is what the final piece of the hole cogwheel looks like. As you can see there is a hole in the centre of the object.
