You can convert the floor of a new factory floor layout, or an existing factory layout, into a solid slab using the Create Solid Floor command. This function is particularly useful when you wish to create a 2D section view in your factory floor drawing that includes a dimension of the floor thickness.
The solid floor defaults to a thickness of 200 millimeters when using a metric assembly template, and 8 inches for a template using Imperial units. Use the Thickness setting in the Floor/Grid Settings dialog box to change the floor thickness to a different value.
