Learn about dividing structural slabs into configurable parts for precast assemblies.
For a structural slab to be eligible for splitting into precast assemblies:
- The Structural parameter under the Structural section of the Properties palette must be selected.
- One layer of the slab structure must be specified as a Structural Material even if only one layer is defined.
- The structural material of the layer must have a defined density.
Span Direction
The span direction of a structural slab determines the beginning edge for segmentation. The following images show the different segmentation placement based on the span direction of a rectangular slab.
Splitting Structural Layers in Multilayered Slabs
Using the structural precast tools, you can include poured concrete, finishes, and other layers, along with precast structural slab assembly layers. The slab must first be transformed into parts, then you can select the structural layer to be split into assemblies.
Splitting Asymmetric Slabs
In some situations, splitting a structural slab generates assemblies with asymmetric shapes.
To force the segmentation along a specified plane, you should first transform the floor into parts using sketched division lines where the appropriate segmentation should render.
You can now select the parts and split them into assemblies using the structural precast tools.
