.skp File — SketchUp Model

SKP is the native file format for SketchUp, a popular 3D modeling application widely used in architecture, interior design, landscape architecture, and woodworking. SketchUp files store 3D geometry, materials, textures, components (reusable object instances), groups, scenes (saved views with camera positions and display settings), layers/tags, and section planes. SketchUp's intuitive push-pull modeling approach makes it one of the most accessible 3D modeling tools, enabling architects and designers to quickly create 3D models from 2D shapes. The SketchUp 3D Warehouse provides millions of free models including furniture, vehicles, buildings, and architectural elements that can be downloaded and imported into projects. SKP files support geolocation through Google Earth integration, shadow analysis for architectural studies, and extensions for rendering (V-Ray, Enscape), BIM integration, and specialized workflows. SketchUp offers both free (web) and paid (Pro) versions, with Pro adding features like solid tools, DWG import/export, and LayOut for construction documents. The format is supported by many third-party tools for visualization and rendering.
