Step Height Plugin

Provides a robust and precise tool for measuring vertical distances between surfaces, known as step height. Widely used in semiconductor, materials science, and precision engineering industries, this plugin enables users to quickly and accurately quantify the height difference between two regions on a 3D surface or profile scan.

It offers intuitive controls and customisable settings for region selection, reference plane fitting, and result interpretation—ideal for characterising coatings, etching processes, micromachined structures, and more.

Unlike Step Height ISO, this can analyse any step height, not only standard ones.

• Automatic and Manual Region Selection
  Easily select top and bottom surfaces using either automatic thresholding or manual region-of-interest tools for more control.
• Flexible Reference Plane Fitting
  Fit reference planes to selected regions using various fitting algorithms (e.g., least squares), ensuring high precision even on tilted or uneven surfaces.
• Multi-Step Measurement Support
  Measure multiple step heights in a single scan, with clear labelling and statistical summary.
• Real-Time Results and Visualisation
  Get instant feedback on measurements with dynamic overlays and annotated results on the 3D model or 2D profile.
• Batch Processing
  Apply step height analysis across multiple datasets for high-throughput environments, reducing time and improving consistency.
• Standards Compliance
  Supports ISO-compliant step height measurement protocols and traceable metrology practices.
• Exportable Reports
  Generate and export detailed measurement reports with images, measurement values, statistics, and metadata.
