Sketchup Joint Push Pull — Crack

If you need a true normal offset and see cracks:

Users report two distinct types of "cracks" when using the tool: sketchup joint push pull crack

If the model is very small or located far from the global origin, SketchUp's internal precision limitations can result in vertices snapping to incorrect coordinates, causing micro-cracks. If you need a true normal offset and

If the geometry is solid but textures look cracked: Here is why that happens

The Joint Push Pull tool is designed to extrude curved surfaces, organic shapes, and complex meshes—things the native SketchUp "Push/Pull" cannot handle. When the tool fails, it creates "cracks" (open seams) or flips the normals. Here is why that happens.

If you’re seeing cracks or gaps when using Push/Pull on connected faces (especially at joints or where faces meet at angles), this short guide helps you diagnose and fix the problem.

When two faces meet at an acute interior angle (like a deep V-groove), pushing them outward can cause the offset geometry to intersect itself. The tool's "crack" is actually its way of aborting a self-intersecting mess.
