ADT plugin for SketchUp
@Last Software today released its , which allows the import of SketchUp's native 3D geometry directly into AutoDesk's Architectural Desktop (ADT) program. In automatic mode, vertical surfaces are translated as walls, horizontal surfaces become slabs and sloping surfaces become roof slabs. A manual mode allows users to specify the exact method of translation for specific surfaces by using the material assignments within SketchUp, while method uses section slices from SketchUp to convert lines to walls or curtain walls in ADT. The SketchUp to ADT plug–in is available for free for a limited time.
