The Slab Tool is similar to Takeoff_Length and Takeoff_Area but for VOLUME. This time-saving tool allows users to generate 3D slabs with several parameters, such as thickness, material texture and layer, then automatically create slabs by simple tracing and closing the path. When your SketchUp template file already has Estimator data assigned to that layer, you can instantly view the estimate generated by this new slab. Positive thickness models UP and negative thickness models DOWN, when traced. Users can create favorite slab types and save them – and choose from favorites at any time.
