Graitec PowerPack propose a specific command for assigning reinforcement to a layer (for example Top or Bottom) for easy and quick filtering of the reinforcement.
The layer might refer to a geometrical location of reinforcement but also to another purpose, such as its function.
The information about the assigned layer is stored using shared parameters: G.Rebar Location for Structural Reinforcement and G.Fabric Location for Structural Fabric Reinforcement.
The assignment is done automatically and manually. The automatic method is applied during reinforcement generation using calculation modules or reinforcement generators in PowerPack. For example, the top bars in the foundation have an automatically assigned value T (a default name for a top reinforcement). This automatic assignment is made to the selected rebars, for example in the case of a foundation to the lower and upper bars in the pad.
The manual assignment is done for selected reinforcement using the Assign Layers command, which is available in the PowerPack Detailing ribbon.
The Assign Layers command opens a special dialog with the list of default/predefined layers.
The content of the list is based on the configuration from the Reinforcement Layers Definition window, opened by the Layers Definition command. The user can modify names for default layers, use the Active option to limit the list of layers that can be available during the assignment and add new positions/layers to the Other group.
The value of the layer parameter is mainly used in the new options of the tools for controlling the reinforcement visibility. Indeed, to the Rebar Visibility functionality, a new group of options for selecting by layers is added.
When the Top or Bottom option is selected, then an additional filtering for reinforcement is activated, respectively by the top and interior or the bottom and exterior layers. When the Selected option is active then the selection of layers for displaying is done through the dialog opened by the Select Layers button.
In addition, three commands are available under the drop-down list under the Rebar Visibility: By layer, Hide All Reinforcement and Show All reinforcement.
Hide All Reinforcement and Show All Reinforcement allow you to quickly turn off or on the visibility of the entire reinforcement in a given view. By Layer allow you to quickly select the reinforcement to be displayed by using the Layer property.
This is particularly useful when generating drawings with separate views, e.g. for bottom/ top reinforcement for slabs or foundations.
