+CAD Module

CAD Integration Software Module

The +CAD module is fully integrated with ScanIP and allows CAD objects to be integrated with 3D images for export as multi-part CAD models or, using the +FE module, multi-part CAE models.

Applications include implant positioning for medical device research, evaluating interactions between anatomies and consumer products, and generating internal structures to reduce the weight of manufactured parts.

+CAD Technical Data

The +CAD module allows the import and interactive positioning of surface objects within image data. In addition, +CAD also offers an internal structures wizard for 3D printing applications. The +CAD module is fully integrated within the ScanIP interface.

Import Formats

  • ScanIP project files (image backgrounds and masks)
  • STL
  • IGES/IGS
  • STEP/STP
  • 3DS

User Interface

  • Fully integrated within ScanIP
  • Visualise surface and mask objects together

Working with CAD and Image Data

  • Surface to mask tool: Conversion of surface objects to image masks by voxelisation. Three available methods:
    • Accurate for manifold objects: when converting watertight surface object
    • Accurate for non-manifold objects: when converting non-watertight surface object
    • Robust: Less accurate but failsafe option for poor quality surface objects
  • Mask to surface tool: Use the current 3D visualisation of a mask to create a surface object
  • Create shape: generate surface object primitives:
    • Cuboid
    • Cylinder
    • Sphere
    • Cone
    • Tube
  • Manipulate surface objects both interactively and by absolute position and orientation:
    • Transform
    • Rotate
    • Scale: aspect ratio preserving or along specified axis
    • Zero position: move surface object to the image space origin
  • Use global, local or user-defined axis for object manipulation
  • Check and fix tool: check for surface errors and attempt to fix them
  • Group surfaces: group surface objects into one single object
  • Ungroup surfaces: create new surfaces by separating a surface object into its connected components
  • Surface to surface Boolean operations: General and Venn diagram interface options:
    • Union
    • Intersect
    • Subtract
  • Digital resurfacing: Use voxelisation and iso-surface extraction to re-triangulate surface objects
  • Auto-pad: Auto pad the image boundary to contain surface object
  • Feature edge editor: Visualisation and selection of feature edges that the meshing algorithms should try to preserve
  • Interactive clipping box for section views of surface objects in 3D

Internal structures wizard

  • Allows shelling and adding a range of internal structures flexibly to any surface object
  • Applications include reducing material usage and weight of 3D printed models
  • Unit cell types available are:
    • Schwartz primitive
    • Schwartz primitive (pinched)
    • Schwartz diamond
    • Schwartz 'W'
    • Schoen gyroid
    • Neovius' surface
    • Cylinder grid
    • Schwartz primitive (2.5D)
    • Schwartz primitive (pinched) (2.5D)
    • Schwartz 'W' (2.5D)

+CAD Scripting

  • Application Programming Interface (API): is an object-oriented library allows access to most of the features of +CAD
  • Support for a variety of scripting languages:
    • Python
    • Iron python
    • C#
    • Visual Basic
    • Boo
    • Java
