Building Information Modeling (BIM) is a design methodology that uses coordinated, high-quality information stored in a single building model to enable design and construction teams to consistently and reliably manage project information across the entire scope. BIM supports large team workflows to improve project understanding and enable more predictable outcomes through increased coordination, accuracy, and earlier informed decisions. Software like Revit Structure uses intelligent, parametric objects and elements with associated information stored in a single model to automatically coordinate changes across any views of the model.

2. Building Information Modeling is a design and
documentation methodology based on
coordinated, high quality information. It
enables design and construction teams to
create and manage information about a
building project consistently and reliably
across the scope of the project. The
information is stored in a single building
model. This ensures that information is
coordinated, consistent, and complete.
3. Building Information modeling supports large
team workflows to improve project
understanding and enable more predictabe
outcomes. The visibility that BIM provides
to all members of the project team
contributes to its success through better
coordination, improved accurary and the
ability to make more informed decisions
earlier in the process.
4. Revit Structure is a purpose-built software for building information
modeling.
Traditional drafting CAD software represent geometry of a design by
using stylized symbols from designated illustrations. Some
examples of these illustrations may be a series of plans,
elevations, and sections. These illustrations are essentially
independent of one another. Building information modeling
software represents as series of intelligent objects and elements
such as walls, beams, schedules, and plan views. These objects
and elements have parametric attributes. The information about
these objects and elements is stored in a single building model.
You can extract any number of different views of the data from
the model.
5. Bidirectional associativity is the ability of the building
information model to coordinate changes made in any
view and propagate these changes out to all other
views. Bidirectional associativity is applied
automatically to every component, view, and
annotation. For example, a change in the size and
location of a column is reflected in all plans, details,
and schedules; all of which are associated with the
column and influenced by the changes and are
automatically adjusted. Revit helps ensure that plans,
schedules, and building sections and elevations are
immediately available, up-to-date, and accurate.
For example:
Flip a section line and all views update
6. Flip a section line and all view updates
Draw a wall in plan and it appears in all
other views including material takeoffs
Change a beam or column type in a
schedule and the change propagates
throughout the graphical and non-graphical
views
7. The term parametric refers to the relationships
among the elements of a building design model.
These relationships are created either
automatically by the software or by you. In
mathematics and mechanical CAD, the numbers of
characteristics that define these relationships are
called parameters; therefore, the operation of the
software is called parametric. It is these parametric
relationships that deliver fundamental coordination
and productivity benefits provided by the building
information modeling methodoly.
8. Beams attached to supporting columns
located on column grids. When a grid moves,
the column moves with it and the beams
length adjust accordingly
A structural truss modeled using constraints
that define the number of bays and lengths of
diagonals. When the span of the truss
changes, vertical members are added where
necessary and the diagonal web members
adjust accordingly.
