Abstract: A method of modeling layout of rigid tubing comprises securing a first component of a lockable adjustment assembly to an end A of a first rigid tube via a first releasable coupling assembly. The method also comprises securing a second component of the lockable adjustment assembly to an end C of a second rigid tube via a second releasable coupling assembly. Further, the method comprises moving the first component and the second component, loosely coupled with each other, relative to each other with only three degrees of freedom to position the first rigid tube and the second rigid tube in a selected orientation with respect to each other. The method also comprises, with the first rigid tube and the second rigid tube in the selected orientation relative to each other, locking the lockable adjustment assembly so that the first component and the second component have zero degrees of freedom relative to each other.

Abstract: A modeling assembly (100) for layout of rigid tubing comprises a first releasable coupling assembly (110) and a second releasable coupling assembly (120). The modeling assembly (100) also comprises a lockable adjustment assembly (130) comprising a first component (140) and a second component (150). The first component (140) is configured to be removably coupled to an end A of a first rigid tube (102) via the first releasable coupling assembly (110). The second component (150) is configured to be removably coupled to an end C of a second rigid tube (104) via the second releasable coupling assembly (120). With the lockable adjustment assembly (130) in the loose coupled state, the first component (140) and the second component (150) have only three degrees of freedom relative to each other. With the lockable adjustment assembly (130) in the locked coupled state, the first component (140) and the second component (150) have zero degrees of freedom relative to each other.

Abstract: Duct fittings can be formed or assembled from two or more components including a collar and a clamp. The clamp and the collar can be assembled and/or mated together to form the duct fittings. The collar can have a first annular portion to which a first layer of a multilayered duct is attached or connected. The collar also can include a second annular portion that can include splines to which a second layer of the multilayered duct is attached. The splines can accommodate or form fluid passageways. The clamp can be located on top of the second layer and can include attachment mechanisms securing the clamp to a support surface.
