+CAD Module

Providing a straightforward method for the import, interactive positioning and integration of CAD models within image data.

The +CAD module (formerly known as +ScanCAD) is a bolt on module to ScanIP which allows CAD objects to be integrated into 3D images. The resulting combined models can then be exported as multi-part CAD models or, using the +FE module, converted into multi-part volume meshes.

New in Version 4


Internal structures for rapid prototyping
  • Seamlessly add complex lattice structures to STL
  • Save material costs whilst maintaining mechanical requirements
  • Additional option to automatically mesh internal structures for FEA

Benefits

  • Combine image and CAD data easily
    Avoid working with image based models in CAD
  • Generate accurate meshes representing combined image and CAD data
    Robust meshing alogorithms in ScanIP and the +FE module
  • Simplify the generation of multiple meshes for testing surgical variability
    Rapid, repeatable and accurate
  • Design surgical guides and templates, introduce scaffolds/micro-architecture
    Seamlessly replicate real-world scenarios

Key features

  • Direct import of most common CAD formats into 3D image
  • User-customisable graphical interface with 2D/3D views
  • ‘On the fly’ repair of non-watertight CAD models
  • Real-time interactive or direct keyboard input for accurate model positioning
  • Constrained motion positioning along user-defined vectors
  • Geometry preserving re-sampling
  • CAD primitives for template generation
  • Internal micro-architecture generation
  • Export combined models as STL or into ScanIP for volume meshing

+CAD Technical Data

The +CAD module allows the import and interactive positioning of CAD models within image data. The resulting combined models can then be exported as multi-part CAD models or, using +FE, converted automatically into multi-part finite element or CFD meshes.

User Interface

  • User controlled view layout and dockable toolbars
  • Conversion of CAD and STL from a surface to image data by voxelisation, three methods:

    • Cuboid
    • Cylinder
    • Sphere
    • Cone
    • Tube
  • Manipulate CAD objects both interactively and by absolute position
    • Transform
    • Rotate
    • Scale: aspect ratio preserving or along specified axis
  • Use global, local or defined axis for object manipulation
  • Image resampling
  • Interactive clipping box for section views
  • Range of visualisation and rendering settings
    • Blending functions: Ray casting, texture mapping
    • Colour mapping
    • Opacity mapping
    • Lighting controls
    • Vertex line visibility
  • Wizard tool allows shelling and adding a range of internal structures flexibly to any object
