Let’s create a robot with detachable arms.
Step 1: From the connectors, grab socket and seated ball. As you can see they can perfectly fit.
Step 2: Grab two cylindrical shapes, place them as shown below.
Step 3: Drag pyramid shape.
Step 4: Place the pyramid and align them as shown.
Step 5: Place socket around the pyramid as shown.
Step 6: Drag a box and cone. Also, align them as shown below. It will be the arm of the robot.
Step 7: Copy the shape into two.
Step 8: Now, align a sphere as shown below.
Hence, we got the idea to how to use the connectors.
