The revit users globally use the bean tool to draw hollow-core planks designing a floor system. The users have noticed that beams are not good answer for hollow-core panels.
Applications: Hollowcore plank are used in a wide range of buildings as floor/roof components. The precast concrete slabs are cut to length for each project. Hollowcore is frequently used in residential, commercial, industrial, institutional and other applications.
The smart floor planning: Smart Floors very accurately and easily creates prestressed concrete floor systems. This Revit add-on modifies offsets and position of floor panels and inserts holes into floor systems.
The Smart floors, which is a powerful Autodesk Revit Architecture or Structure extension for floor panel placing and alteration, distributes panels in predefined area. The panel consists of the Floor and Generic Model family that makes a hole.
A designer can use Smart Floors to create a hollow-core profile and with no problem apply this to a floor type. Smart Floors shows the units according to the project units so you can change the floor system units from metric to imperial if you need.
