On Wednesday Autodesk announced the launch of Autodesk Revit LT 2013. As the name suggests, Revit LT is based on the Revit platform and is an intuitive 3D Building Information Modeling (BIM) application. Revit LT is a cost-effective entry point for architects, designers and building professionals to transition to BIM workflows.
We have already received inquiries about its API support. The answer is: no API with Revit LT. If you are a developer who has a Revit application, there is no need to worry about testing your application against it.
