The project required for GEOMETRIA to design a steel structure dome for the Intersolar exhibition in Munich, Germany. The dome was part of the Qcells exhibition, designed by Tomexpo AG.

The design is based on a network of illuminated arcs that form a dome structure of 10,5m diameter and 2,7m height. The base structure for was done with round steel pipes and a plywood ring for start and end fixation.

The main task for GEOMETRIA was to meet the design intention with least possible amount of steel material, optimised distribution for structural purposes, and with a minimum number of different arc radiuses.

For assembly purposes, the arcs could not intersect with each other, but they could only meet in overlapping layers. It was possible to limit down the number of layers to three, for a pleasing design solution and constructability. Overall, the dome is built up of 27 arcs, based on just 12 different ones.

GEOMETRIA created the parametric 3D model for design and optimisation purposes, with implementation of name and colour codes of each arc, according to their layer and length.

The model provided a precise material list for the fabrication data of all steel-pipe arcs and GEOMETRIA produced detailed assembly drawings, including plans of each arc and the positions of their connection points.
