If you have landed on this page, you are likely frustrated. You have installed the legendary extension by Fredo6, you clicked on a face to extrude it, and instead of a smooth, thick shell, your model exploded into a mess of reversed faces, missing geometry, or what looks like a "crack" in your 3D model.
It can only work with the geometry you give it. If your base mesh has microscopic errors, the extrusion will magnify them into visible cracks. sketchup joint push pull crack
The Joint Push/Pull tool in SketchUp is designed to create a joint between two objects by pushing or pulling one object into another. This tool is useful for creating complex assemblies and intersections between objects. However, some users have reported that when using this tool, the joint may crack or become distorted, particularly when working with certain types of joints, such as:
If the crack is already there:
By embracing the capabilities of the Joint Push/Pull tool and SketchUp as a whole, you can unlock new possibilities in 3D modeling and design. Whether you're crafting intricate architectural details or conceptualizing innovative products, SketchUp's robust features and extensive community support make it an invaluable tool in your creative arsenal.
The free version allows limited "extrude along normal." It is slower for large faces but avoids cracking 90% of the time. of SketchUp you're using (Pro, Pro 2026, Free)
: By streamlining the modification process, this tool significantly reduces the time required to make complex adjustments to a model. This efficiency gain enables designers to explore more iterations and refine their designs more thoroughly.
