I'm assuming you're looking for information on a specific technique in SketchUp, a popular 3D modeling software. Here's what I found:
What are you trying to extrude (e.g., curved walls, organic terrain, furniture details)?

While SketchUp’s native Push/Pull tool cannot handle curved surfaces out of the box, you can achieve similar results using native tools if budget is a strict constraint:
The SketchUp Extension Warehouse and Sketchucation store host thousands of plugins. Look for open-source or free legacy extrusion tools that offer specific functionalities of Joint Push Pull—such as vector pushing or normal-based extrusions—without requiring a paid license or risking malware. Conclusion I'm assuming you're looking for information on a
Users can choose how border faces are handled with options including contour, grid, or none, giving you precise control over the final geometry.
However, even experienced modelers encounter a frustrating issue: when pushing geometry. This article explains why this happens and provides a comprehensive guide to fixing it. What is Joint Push Pull and Why Use It? Look for open-source or free legacy extrusion tools
The tool tries to create perpendicular faces, but when the geometry bends too sharply, the edges fail to meet properly, leaving a gap [2]. How to Fix the Joint Push Pull Crack/Gap
