Joint Push Pull Sketchup — 2021

The Joint Push Pull (JPP) extension for SketchUp 2021 represents a significant advancement in non-planar surface extrusion. Unlike SketchUp’s native Push/Pull tool—which operates only on flat faces—JPP allows users to extrude curved, faceted, and multiple contiguous faces simultaneously. This paper examines the mathematical underpinnings, workflow integration, and practical applications of JPP within SketchUp 2021’s API environment. Case studies in architectural detailing, terrain modeling, and organic form generation illustrate its utility. Limitations regarding mesh topology and extension conflicts are also discussed.

Extrudes each selected face along its own individual perpendicular (normal) axis. Unlike the Joint mode, it does not keep the faces interconnected, resulting in separated, exploding shapes. Joint Push Pull Sketchup 2021

The flagship tool. It pushes multiple faces along their average normals, keeping them connected. Perfect for thickening a curved wall or a car hood. The Joint Push Pull (JPP) extension for SketchUp

Tap the on your keyboard to lock the extrusion to a specific axis (Up Arrow for Blue axis). Unlike the Joint mode, it does not keep

Pushes each face along its own individual normal. Unlike the Joint version, this will usually result in the faces "splitting" apart if they aren't parallel.

If you’ve spent any time in SketchUp, you know the standard is the bread and butter of 3D modeling. However, you’ve likely hit its biggest limitation: it only works on flat faces. If you try to push/pull a curved surface or multiple faces at different angles simultaneously, the native tool simply gives up.
