Spoolit produces dimensionally accurate 2D and 3D spooled drawings with lists of materials, required for pre-fabrication and manufacturing. Ductwork, pipe work and electrical containment service models can be isolated into data rich sections. Those chosen, can be printed out specifying the areas required for pre-fabrication with the associated accurate dimensional data. Entire runs of ductwork and pipe work can be produced in the same manner using Spoolit.
