Revit LT is the affordably priced version of Revit, the foremost intuitive BIM design software on the market. This cut-down version helps you produce better 2D plans and views.

Moreover, creating smart, high-quality 3D architectural models and documentation within a coordinated environment has now become easier than ever. Share your designs with stakeholders and other users of the software on the basis of the Autodesk Revit or AutoCAD platforms. 

When you purchase a licence for Autodesk Revit LT 2018, you also have the right to use the 2015 version. This is the only way, in the new licensing structure, to "buy" Revit LT 2015 (further information on licensing).
