Here’s a SketchUp version list (major releases), followed by a method to generate a solid piece (watertight 3D form) in each.
A solid in SketchUp = single group/component with no stray edges inside, no holes, and manifold (every edge belongs to exactly 2 faces). sketchup version list
SketchUp is a 3D modeling computer program for a wide range of drawing applications such as architectural, interior design, landscape architecture, civil and mechanical engineering. It was developed initially by @Last Software of Boulder, Colorado. Unlike traditional CAD software which relies on geometric constraints and complex parametric history, SketchUp utilizes a direct manipulation interface allowing users to "push" and "pull" surfaces to create geometry. This paper details the version history to provide a reference for software archiving and compatibility assessment. Here’s a SketchUp version list (major releases), followed
Introduced Layers (now called "Tags") and the Component system (making repeated objects like chairs or trees update globally). The "Follow Me" tool was added for extruding along paths (e.g., creating pipe bends or crown molding). Further subscription-centric features
