The Marvin Design System, first introduced in 1993, is no longer supported or available. All products and updates can be found in the 2D drawing library. We also have a very robust 3D Library of symbols in the native CAD formats for architects and design professionals. Symbols of standard window and door products are ready to insert directly into your AutoCAD Architecture, SoftPlan, Chief Architect, ArchiCAD, VectorWorks, Revit and SketchUp Version 6 and now SketchUp Dynamic Components (Version 7 & 8) plans. Self-installing files are available.
