Incorrect calculation of quantities in Revit

  • hello
  • I'm Obaida Al-Rasheed, I'm an architect
  • I am trying to help develop Revit Architectural software
  • I found an error in the program, which is calculating the quantities of materials
  • If we draw a room, for example, when calculating the quantities of plastering, we find the area of the external plastering equal to the area of the internal plastering. This means that the program does not calculate the area of the surfaces, but rather depends on the length and height of the wall, and thus the thickness of this wall has been neglected at the level of one room. When the calculation is related to a complete project, the error becomes greater
  • There is also an error in calculating the interior plaster on the floors, as the calculation is made without deleting the quantities adjacent to the walls, and this increases the error rate
  • The truth is that I lost confidence in calculating quantities through the Revit
  • I am trying to avoid these errors
  • Thanks

This doesn't make any sense. If you are calculating surface area of the wall - which IS equal to length x height - what does the thickness of the wall matter?

    Create Parts and create material take-off schedule for Parts.

    Model finish floors separately from structural floor and draw their boundary precisely (i.e. wall to wall)

Allow Join and Miter corners.  Interior and Exterior Material Area Calculations should be accurate (or very close).  Note also that Join Geometry will remove material at union depending on Join Order.
