This new 3DReshaper® option allows you to expand the scope of applications from 3D scanning, especially in the field of reverse engineering.

From any point data resulting from a digitization, you can generate a CAD model (such as IGES or STEP), usable in computer-aided design, manufacturing or engineering software.

The polygonal mesh modeling of 3DReshaper creates quality models, made up with hundreds or thousands of triangles. These 3D meshed models are ready for rapid prototyping, tool path generation, simulation.

However sometimes, a “continuous” model is required by CAD-CAM software. This process of making a CAD model is also called “reverse-engineering” because you generate a continuous model. This module allows you to make CAD Surface reconstruction starting from a mesh.
CAD Surface means NURBS* and BSpline surfaces that are fitted on your original mesh.

3DReshaper is a complete software solution which offers all the necessary functions for the construction and the processing of BSpline and Nurbs* surfaces in order to output a typical CAD model.

The process to turn a mesh model into a CAD part is to easily design sets of patches by constructing a network of curves on the mesh.

The curves which delineate the patches will be converted to BSpline curves and then to independent surfaces which will constitute the CAD model when grouped together. Quality control tools of the patches are aslo available and gives you full ability to improve the quality of your CAD model at the different steps.

The CAD surfacic modeler is often essential for different reasons:

  • Interoperability
  • The technical documentation of a particular device doesn't not exist anymore, and the person who built it is no longer available.
  • Product analysis and competitive technical intelligence.
  • Digital update and correction.
  • Security or quality auditing.
  • Academic and learning purposes...

*Non-uniform rational basis spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces which offers great flexibility and precision for handling both analytic and freeform shapes.

Point cloud to CAD model

 

From point cloud to CAD model, via meshing. Once the Nurbs surfaces are grouped together, this part will be made up with one single surface.
