Cast unit drawings are dimensional, form work, or reinforcement drawings used in concrete design and construction. They show cast-in embeds, edge chamfers, and hard and soft insulation. Cast unit drawings that show cast-in-place concrete structures usually use large sheet sizes, for example, A1 or imperial standard size 24" x 36". Drawings that show precast structures usually use smaller sheet sizes, for example, A3 or imperial standard size 11" x 17".

You can only create cast unit drawings of concrete parts and cast-in embeds (steel parts or assemblies added to a cast unit). Cast unit drawings also show the bolts and welds in steel parts. The volume and weight information of the cast unit remains accurate even if there are cuts inside the cast unit.

Cast units have the cast unit type part property - they are set either Cast in place or Precast. It is important to use the correct cast unit type, because some features, for example, numbering and continuous concrete are based partly on the cast unit type. In the Rebar Detailing configuration, you can create cast unit drawings of cast-in-place cast units only.
