Visualize STEP data on the desktop or from any web-based application

  • Visual Styles

    Use different visual styles to customize your rendering of silhouettes, obscured (hidden) edges, transparency and more.

  • 性能

    Spatial filtering and other performance enhancing techniques provide fast visualization of STEP data, even for large models.

  • 导航

    Use a set of standard features for navigating through a model such as zoom, pan, 3d rotation and more.

  • Materials and Lighting

    Use materials and lighting effects to create a high-quality, realistic visual representation of a model.
