New attributes and changes to existing attributes

Under Precast elements, element-specific the following attributes are now also available:

• Density of reinforced concrete (catalog); (@36100@, Double) and Density of concrete (catalog); (@36101@, Double). These evaluate the density of reinforced concrete and density of concrete catalog entries for the relevant steel grades from the concrete grade catalog . With multi-layer precast elements, the special index can be used to set the leaf that should be evaluated. The attribute can also be analyzed in the case of concrete areas.
• Thermal conductivity (catalog); (@36102@ Double). Evaluates the catalog entry Thermal conductivity of the relevant insulation material from the insulation material catalog . With multi-layer precast elements, the special index can be used to set the leaf that should be evaluated. The attribute can also be analyzed in the case of insulating layers.
• Concrete cover on side or on top/visible; (@36103@, Double). Evaluates the lateral concrete cover on the upper/visible reinforcement layer. With multi-layer precast elements, the special index can be used to set the leaf that should be evaluated.
• Concrete cover on side or at bottom/invisible; (@36104@, Double). Evaluates the lateral concrete cover on the bottom/invisible reinforcement layer. With multi-layer precast elements, the special index can be used to set the leaf that should be evaluated.

The in-situ concrete layer is generally no longer taken into account with walls that have an in-situ concrete layer (double wall, thermal wall with in-situ concrete layer and composite sheeting wall) that are created via Design (iWall) when calculating the area of the surface (attribute Area in Precast elements, element-specific).
