Sketchup Round Corner !!better!! Crack Top -

Before applying any rounding, scale your entire model up by 10x or 100x. This bypasses the "tiny face" limitation. Once the rounding is finished, scale it back down—the tiny faces will remain intact.

Use the Preview mode in FredoCorner to see if your offset is too large. If the preview shows red or overlapping lines, reduce the radius until they disappear.

SketchUp has difficulty forming very small faces (under 1mm or 1/16 inch). When you round a corner with a high segment count, the resulting faces may be too small for SketchUp to "heal," leaving a gap or crack. sketchup round corner crack top

While SketchUp is incredibly versatile, it wasn't natively designed for complex edge rounding. To get professional results, you’ll almost always need a specialized extension or a few expert workarounds. 1. Why Do "Cracks" Appear?

If you’ve spent any time 3D modeling, you’ve likely encountered the frustrating or broken geometry issue when trying to round off a corner in SketchUp. This typically happens when the software's internal engine struggles to calculate complex intersections, often resulting in missing faces or "cracks" on the top surface. Before applying any rounding, scale your entire model

If your rounding radius (offset) is larger than the available surface area, the geometry will overlap and break the top face. 2. Best Solutions: FredoCorner vs. RoundCorner

While simpler and faster for basic cubes, it is "greedier" with face generation and often fails on non-orthogonal edges. If one fails, many pros keep both installed as a backup. 3. Step-by-Step Fix for Cracked Geometry Use the Preview mode in FredoCorner to see

Mastering SketchUp: How to Fix "Crack Top" and Geometry Issues in Round Corners

This is the newer, more powerful tool. It uses an improved algorithm that handles complex, irregular shapes much better than its predecessor. It includes a Repair button and parametric abilities, allowing you to edit or undo rounding if it creates a crack.

If the top face of your object isn't perfectly flat, standard rounding tools will fail to calculate how the curve should meet the surface, leading to geometric "tears".
