The modular system forms a bar structure, having bars (4) with T-section grooves joined together at nodal points by hammerhead bolts (3). At the nodal point the bars are joined together via a nodal member (2) with butt faces (6) for the ends of three or more bars radiating from its central axis (7). The butt faces are at an acute angle (a) to this axis. ADVANTAGE - Allows information of any uneven surface, e.g. on a roughly spherical structure.
