Boundary beams properties

To assign the properties to the boundary beams, disconnect all layers except the layer vigas_de_borde . Then choose:

Data->Concrete properties->Concrete rec section

and assign to all the active lines. To check that local axes are correct, choose:

Draw->This concrete rec section->Include local axes

In the properties window.

As the lines that define these beams are the contour of surfaces, they are not meshed by default. To force them to be meshed choose:

Meshing->Mesh criteria->Mesh->Lines

And select all the active lines.
