I can provide custom shortcuts or troubleshooting steps for your exact setup.
The native is one of the most intuitive functions in 3D modeling, but it suffers from a major limitation: it only works on single, flat faces along their individual normal vectors. If you attempt to project a complex curved surface, a sphere, or multiple selected faces simultaneously, the default toolkit fails.
Joint Push Pull (JPP) Interactive is a popular extension for SketchUp, primarily used to that the native Push/Pull tool cannot handle. Overview Developer: Fredo6 joint push pull interactive free
Extrudes multiple contiguous faces along their average surface normals. It maintains a connected, smooth outer shell.

: Extrudes surfaces while automatically rounding the resulting edges. Interactive Mode Features Before diving into the resources, let’s break down
Options to keep or remove the original faces and generate side faces automatically. 📥 Installation & Cost Free (Donations to Fredo6 are encouraged). Available via SketchUcation Extension Store Dependency: (a free shared library) to be installed first. Compatibility: Works with most modern versions of SketchUp Pro and Make. 💡 Best Use Cases Architectural Modeling: Adding thickness to complex wall layouts or curved facades. Furniture Design: Creating shells for upholstery or rounded wooden panels. Terrain Modeling: Giving depth to contoured landscape meshes. ⚠️ Important Note
It can "thicken" curved surfaces by automatically filling in the joints between adjacent faces during extrusion.
Molding/Tapering: Constrains or widens the extrusion profile dynamically to form sloped, tapered, or pyramidical projections. How to Install and Set Up Joint Push Pull If you attempt to project a complex curved
It mimics the visual response of the native SketchUp Push/Pull tool but applies it across multiple selected surfaces simultaneously. Every face moves strictly along its own perpendicular axis.

Best for: Physics and Biomechanics teachers. While PhET is famous for circuit builders, their Forces and Motion and Balancing Act simulations are perfect for joint mechanics. Use the "Tug of War" simulation to understand net force. While it is not a human elbow, it visualizes the push-pull dynamic on a pivot point (the joint). It is 100% HTML5, works on iPads, and is completely free.
