SketchUp Studio (2026 Edition)

The ultimate SketchUp bundle for Windows users. In 2026, it features the 'AI Render' engine for viewport photorealism and a revamped Revit Importer (supporting RVT 2015-2026). It includes V-Ray for photoreal visuals and Scan Essentials for point-cloud workflows. While powerful, the high annual cost and 'Windows-only' status for its best features make it restrictive for many designers.
