Every time she clicked on a curved face, SketchUp gave her the same error: “Cannot extrude curved or triangulated surfaces.” Her beautifully wavy roof remained a flat, useless shell.
Pop.
Maya was an architectural student, and she had a problem. Her studio project was a modern art museum with a stunning, swooping concrete roof. In her mind, it looked like a ribbon floating in the air. But in SketchUp, it looked like a pile of broken cardboard boxes. --- Joint Push Pull Sketchup Plugin Download
Maya remembered her professor’s warning: "Never download plugins from random websites. They carry malware like viruses and ransomware."
Frustrated, Maya opened her browser and typed: Every time she clicked on a curved face,
She learned that Joint Push Pull (JPP) is a legendary extension created by Fredo6, a famous SketchUp plugin developer. Unlike the standard tool, JPP doesn't just push flat rectangles. It can push any face—curved, bumpy, vertical, or twisted—outward or inward to create a solid, real-world thickness.
In half a second, her flat, invalid surface became a beautiful, solid, 3D-concrete roof with perfect, even thickness. No errors. No broken geometry. Her studio project was a modern art museum
She had drawn the complex shape using organic curves and imported topography. But when she tried to give it thickness—to turn her paper-thin surface into a real 3D slab of concrete—SketchUp’s standard tool refused to work.
