This solution helps designers to draw documents and lists the necessary reinforcement for their buildings in ArchiCAD. The application provides tools to define all 2D drawings as well as complete 3D models.

The solution contains a library of different reinforcement objects and an Add-on. They provide great freedom in defining constructions and also help to specify complex objects. Eptar Reinforcement also checks the rebar ID numbering and corrects it if is necessary. With Reinforcement tool, users can simply calculate the necessary amount of rebars. Iron list is available on the floor plan just as the interactive schedule.

  • Automatic reinforcement of straight, slanted and curved
  • Automatic reinforcement of roofs with Mesh and Rebar elements
  • Automatic reinforcement of complex roofs
  • Automatic reinforcement of multiply roof surfaces
  • Most used rebar and stirrup forms are preset, but custom polygonal forms can be set too
  • Steel elements can be rotated, thus more difficult constructions (e.g. stairs) can be modeled
  • Complex elements (columns, beams and crownings) can be defined
  • Many view and display options
  • Cutting list generation
  • Changes can easily be made on the layout and in the Object Settings window as well
  • License borrowing: get for limited time (7 days) the activation key offline. After this time period the key become online again. This option is but permanent, and you can use it at any time. It can be ordered for your existing license, too.
