Announcing Autodesk Revit LT

For the nonce, here is an announcement completely unrelated to the Revit API. In fact, the product announced is specifically designed to not be customisable.

Autodesk today announced Autodesk Revit LT software, a new addition to its award winning family of Revit software products. Designed for architects, designers and building industry professionals using 2D workflows who are looking to transition to the Building Information Modeling (BIM) process, Autodesk Revit LT software delivers a focused 3D application to help users create higher-quality and more accurate designs and documentation.

"Autodesk Revit LT reflects our commitment to provide architects, designers and building professionals, particularly those in small firms, the tools they need to ease the transition to get started with – and take advantage of – a BIM workflow," said Amar Hanspal, Autodesk senior vice president, information modeling products. "With Revit LT, customers can deliver higher-quality, more accurate designs and documentation – allowing them to bring projects to market faster and save time and money."

Autodesk Revit LT is built on the Revit platform for BIM and allows users to create designs efficiently with 3D, real-world building objects to produce reliable, coordinated documentation faster. Revit-based applications help deliver better coordination and quality, and can contribute to higher profitability for architects, design professionals and the rest of the building team. Some of the benefits of Revit LT include:
