: Select your plan lines, right-click, and choose Explode . The plugin explicitly requires exploded curves to properly isolate the start and end steps.
To ensure that neither your digital models nor your physical construction projects suffer from top-stair cracking, implement these best practices: s4u stair crack top
| Issue | Possible Cause | Solution | | :--- | :--- | :--- | | The plugin menu parameters don’t change after entering new values. | A bug in some versions may prevent direct menu editing. | Use keyboard commands or type parameters directly into the dialog. Alternatively, restart SketchUp and try again. | | The generated stair does not match the 2D plan (e.g., treads are misaligned). | The selected face(s) may not represent a valid stair outline, or the “Rise” value is inconsistent with the total height. | Double‑check the plan: each tread should be represented by a separate rectangle. Adjust the Rise value so that total height is evenly divisible by it. | | Handrails do not generate at all. | This feature may be disabled in the trial version, or the “Offset” value may be set to zero. | Ensure you are using the paid version and that “Generate Handrail” is checked. Set an offset distance greater than 0. | | The plugin crashes or fails to install. | Incompatible SketchUp version or corrupted RBZ file. | Verify that your SketchUp version supports the plugin (typically 2016–present). Download a fresh copy of the RBZ file and reinstall. | | Materials applied to the stair disappear after an update. | Dynamic update recreates geometry, overwriting custom material assignments. | Apply materials after finalizing the stair design, or use SketchUp’s “Component” strategy to lock materials in place. | : Select your plan lines, right-click, and choose Explode

To avoid "cracks" or visual artifacts, it is recommended to explode all curves and ensure your start and end steps are clean 2D segments before running the plugin. Compatibility Supported on versions from 2022 through 2026. Available for both Windows and Mac. Languages:
