If you are using the newer and encountering holes, the culprit may be the "Super Rounding" feature. This advanced option attempts to create an extremely smooth finish but can inadvertently create "tight" geometry that fails to form a face.
SketchUp is a , not a "solid" or NURBS modeler like SolidWorks or AutoCAD. This means it represents all surfaces as a mesh of connected polygons (triangles and "ngons"—polygons with more than four sides). While powerful for architectural and design visualization, this polygon-based system has inherent limitations, especially when creating highly detailed, curved geometry. sketchup round corner crack top
: Rounding holes or non-orthogonal intersections can sometimes confuse the algorithm, causing it to skip the top face or leave "bad geometry" at the corners.

Give you a step-by-step method to clean up "reversed" (blue) faces using the Default Tray.
: If the top face isn't perfectly flat, the plugin may struggle to "stitch" the new rounded geometry to the existing face, resulting in visible seams or missing surfaces. How to Fix and Prevent Cracks
