Revit Guide 2019

Revit is a parametric modeling software that captures relationships between building elements. Changes made to one element, like moving a wall, will automatically update related elements like doors. There are three types of elements in Revit - model, datum, and view-specific. Model elements represent 3D geometry like walls and doors. Datum elements help define the project context with grids and levels. View-specific elements only display in certain views to document the model, like dimensions. Autodesk offers Revit tutorials on workflows for existing conditions modeling and coordinating designs across disciplines.

Revit Fundamentals

1. Parametric Modelling

Parametric modeling refers to the relationships among all elements in a project that enable
the coordination and change management that Revit provides. These relationships are
created either automatically by the software or by you as you work.
o A door is a fixed dimension from an adjacent partition wall. If you move the wall, the
door retains this relationship to the wall.
o The edge of a floor or roof is related to the exterior wall such that when the exterior
wall is moved, the floor or roof remains connected. In this case, the parameter is
one of association or connection.
o Rebar is spaced equally across a given element. If the length of the element is
changed, the relationship of equal spacing is maintained. In this case, the parameter
is not a number but a proportional characteristic.
Revit uses 2 key concepts that make it especially powerful and easy to use. The first is the
capturing of relationships while the designer works. The second is its approach to propagating
building changes. The result of these concepts is software that works like you do, without
requiring entry of data that is unimportant to your design.
o Element Behavior in Revit
Revit uses 3 types of elements in projects: model elements, datum elements, and view-
specific elements.
o Model elements represent the actual 3D geometry of the building. They display in
relevant views of the model. Examples:
 Walls, windows, doors, and roofs
 Structural walls, slabs, and ramps
 Sinks, boilers, ducts, sprinklers, and electrical panels

o Datum elements help to define project context. For example, grids, levels, and reference
planes are datum elements.
o View-specific elements display only in the views in which they are placed. They help to
describe or document the model. For example, dimensions are view-specific elements.
There are 2 types of model elements:
Hosts (or host elements) are generally built in place at the construction site.
Examples: Walls and ceilings, Structural walls and roofs

Model components are all the other types of elements in the building model.
Examples: Windows, doors, and cabinets,
Beams, braces, and structural columns
Sinks, boilers, ducts, sprinklers, and electrical panels

There are 2 types of view-specific elements:


Annotation elements are 2D components that document the model and maintain scale on
paper. For example, dimensions, tags, and keynotes are annotation elements.
Details are 2D items that provide details about the building model in a particular view.
Examples include detail lines, filled regions, and 2D detail components.
