ABSTRACT:
A plurality of interchangeable straight and curved short cylindrical module segments are selectively and releasably joined together end-to-end manually and rotated relative to one another to form full-scale three-dimensional models of desired complex shapes of tubing, pipe, and conduit configurations. The segments are provided in sets having outside diameters corresponding to the outside diameters of conventional tubing, pipe or conduit and have a circumferential scale at each end to visually determine the relative rotation between one segment and an adjoined segment. When assembled, the model provides accurate shapes and dimensions to aid in designing, laying out, cutting, and fabricating tubular members, and for forming tubular configurations from pre-bent metal tubular sections and the proper relative rotation between them.
