Features

  • Open anything

    Supports up to 10 STL, PLY, and OBJ meshes at once.

  • Measure

    Point-to-point measurements, plus automatic dental arch detection with an editable curve and slicing along the arch.

  • Align & verify

    Three-point alignment and one-click align capability.

  • Occlusion heatmap

    Virtual articulating paper and intuitive side-by-side occlusal views.

  • Scanbody swap

    Instantly replace a set of scanbodies with another and export. Support for hundreds of scanbodies coming soon.

  • Hybrid to Adapted Waxup

    Turn a hybrid designed elsewhere into a watertight Adapted Waxup with every MUA seat and screw channel filled, plus the scanbody of your choice stamped at every MUA.

  • Combine

    Fuse, subtract, or merge any two meshes into one file.

  • Engrave & emboss

    Type a name or case ID and stamp it onto any surface.

  • Slice

    Live cross-section pane with measurements that dynamically follow the slice as it sweeps.

  • Edit mesh

    Lasso and pick-piece selection, cut away debris, close holes, plane cuts by gizmo or a drawn line, bridge two selected areas, and soft-warp with adjustable falloff.

  • Sculpt

    Add, remove, smooth, flatten, and push-pull brushes with a surface-draping cursor — straight from RapidArch Web.

  • Scale

    Uniform, per-axis, or gizmo scaling about any pivot — made for print-shrinkage compensation.

  • Print to DentaFab

    Nest on the real DentaFab plate, auto-generate supports with presets, hand-edit pillars, add a contour raft, then save a print-ready STL or send it over Wi-Fi.

  • Convert formats

    Save any mesh as an STL, PLY, or OBJ file.

  • QC report

    Case notes and quality stats composed into a PDF for patient records or for your lab.

  • Built-in updates

    Automatically checks for new versions so you never miss out on new features.
