Types of Connections
There are three primary ways in which a rod may be joined to a connector:
- Most commonly, the rod's head is inserted into a connector's slot which holds the rods together.
- A rod may also be "snapped in" perpendicular to a connector. It is harder to insert and remove rods this way, but they are for the most part immobile. There are four grooves on rods which allow for rods to be attached in this method in four different directions. They can be slid in the slot, but the heads on the rods stop from further sliding.
- Most connectors have an eye through which a rod may be threaded. The rod will slide out unless a connection is made using one or both of the previously mentioned methods.
Special pieces, commonly called 3D connectors, connect differently.
- They connect using the first and second ways mentioned.
- Their hole has been removed and instead, a special locking system is put in.
- This locking system allows two 3D connectors to be directly attached and kept in place.
- The locking system is the basis for all 3D creations

Famous quotes containing the words types of, types and/or connections:
“The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.”
—Loris Malaguzzi (1920–1994)
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“The conclusion suggested by these arguments might be called the paradox of theorizing. It asserts that if the terms and the general principles of a scientific theory serve their purpose, i. e., if they establish the definite connections among observable phenomena, then they can be dispensed with since any chain of laws and interpretive statements establishing such a connection should then be replaceable by a law which directly links observational antecedents to observational consequents.”
—C.G. (Carl Gustav)
