Dynamo is similar to and takes inspiration from the Grasshopper visual programming language and environment for Rhino. In addition to the node based interface Dynamo can be scripted with the Design Script language and Python. Modeling[ edit ] The Revit work environment allows users to manipulate whole buildings or assemblies in the project environment or individual 3D shapes in the family editor environment. Modeling tools can be used with pre-made solid objects or imported geometric models.
However, Revit is not a NURBS modeller and also lacks the ability to manipulate an object's individual polygons except on some specific object types such as roofs, slabs and terrain or in the massing environment. Revit includes categories of objects 'families' in Revit terminology. These fall into three groups: Revit families can be created as parametric models with dimensions and properties. This lets users modify a given component by changing predefined parameters such as height, width or number in the case of an array.
In this way a family defines a geometry that is controlled by parameters, each combination of parameters can be saved as a type, and each occurrence instance in Revit of a type can also contain further variations. For example, a swing door may be a Family.
It may have types that describe different sizes, and the actual building model has instances of those types placed in walls where instance-based parameters could specify the door hardware uniquely for each occurrence of the door. Due to the copyright nature of project work, it is rare and impractical to be able to buy fully 3D modelled Revit project models. Indeed as most projects are site specific and bespoke, obtaining an existing model is in many instances unsuitable. Where do you start? You certainly don't want to ditch everything you know in favour of a format you don't understand.
For architects and building designers, the shift to BIM doesn't have to be difficult; all you need is the right program. As a stripped-back version of the full Autodesk Revit software, Revit LT is directly targeted towards architects, and cuts out the non-essential tools in favour of a more streamlined program.
As an added bonus, it's also cheaper and can be flexibly scaled based on the number of desktops you need it to run on. This means that firms don't have to sacrifice traditional 2D drafting and detailing tools and can integrate BIM into their operations at their own pace. Once you've got more experience with BIM under your belt, you can always upgrade to the full Revit software, but for starting out, the suite provides the perfect compromise. The benefits of BIM for architects For many architects, there's a bit of resistance to the idea of moving away from what's worked in the past.

From the outset, Revit was intended to allow architects and other building professionals to design and document a building by creating a parametric three-dimensional model that included both the geometry and non-geometric design and construction information, which is also known as Building Information Modeling or BIM Eastman C. At the time, several other software packages—such as ArchiCAD and Reflex—provided a three-dimensional virtual building model, and let the user control individual components via parameters parametric components. Two key differences in Revit were that users created parametric components in a graphical "family editor" rather than a programming language, and the model captured all relationships between components, views, and annotations so that a change to any element automatically propagated to keep the model consistent. The concept of bi-directional associativity  between components, views, and annotations was a distinguishing feature of Revit for many releases. The ease of making changes inspired the name Revit, a contraction of Revise-Instantly.
