SketchUp remains the most accessible 3D modeling tool in architecture, and its extension ecosystem has been enriched with AI-powered add-ons. Plai generates photorealistic materials and textures from text descriptions directly within SketchUp, replacing the need to source or photograph materials. Dibac AI acts as an intelligent drawing assistant that recognizes what you're trying to draw (a staircase, a railing, a roof) and provides smart construction assistance. Skalp AI automates the laborious process of creating architectural section drawings, applying correct hatching and cut patterns based on material recognition. SketchUp's AI Modeler (beta) takes text descriptions and generates 3D geometry directly, enabling architects to prototype ideas without manual modeling.
AI-powered generative design and automation inside Revit
Generative design explores thousands of design options simultaneously. Forma handles massing and environmental analysis. Automates clash detection, sheet creation, and documentation tasks.
AI-powered CAD with automated drawing completion and BIM
AI autocompletes 2D drawings, recognizes architectural shapes, and generates BIM models from 2D plans. Cost-effective AutoCAD alternative with smart AI features.
Collaborative VR design tool with AI mesh generation
Design together in VR/AR using natural gestures. AI generates meshes from sketches and converts models directly into Revit or SketchUp. Ideal for co-design sessions with clients.
