In the "Introduction" group of the main toolbar, the main features for entering reference elements, modelling the structure and entering connections can be found. Some of these tools are common to other CYPE programs.
Grids are reference lines that make the geometrical modelling of the structure easier. They can be used during the modelling phase to draw any element, as they can be snapped, just like any other element in the model. Grids and reference lines are particularly useful for placing the bars of a modular structure, or for projects that are being 100% developed in StruBIM Steel without prior import.
