Joint Push Pull Sketchup 2021 [portable] -

| Problem | Likely Cause | Solution | |---------|--------------|----------| | "Invalid selection" | Non-manifold edges or open geometry. | Use Solid Inspector ; weld edges first. | | Extrusion flips inside-out | Negative distance value. | Enter positive distance. | | Slow performance | Too many faces / high subdivision. | Reduce selection size; lower angle tolerance. | | Thickness fails | Intersecting geometry during offset. | Increase offset distance or simplify mesh. | | LibFredo6 error | Outdated or missing LibFredo6. | Install latest LibFredo6 for SketchUp 2021. |

The Joint Push Pull tool is a powerful feature in SketchUp that enables users to push and pull faces, edges, and vertices in a model while maintaining their connections to other entities. This tool is particularly useful when working with complex models that require precise control over the geometry.

Mimics the classic CAD extrusion style, maintaining the exact profile shape along a path.

The flagship tool. It pushes multiple faces along their average normals, keeping them connected. Perfect for thickening a curved wall or a car hood.

Allows you to push or pull faces in a specific direction (e.g., locking to the Blue axis by pressing the Up Arrow ), which is useful for flattening terrain or creating vertical extrusions from sloped surfaces.

Extrudes faces along a single, specified directional vector (e.g., straight up along the Blue axis), regardless of which way the faces are pointing.

In SketchUp 2021, the extension (by Fredo6) is a vital tool for extruding complex, multiple, or curved surfaces that the native Push/Pull tool cannot handle. Because SketchUp treats curved surfaces as a collection of individual flat faces, the standard tool can only move one face at a time, often breaking the geometry.
