Reverse Engineering

A 3D scanner is a device that captures a real object or environment as a 3D shape data. The collected 3D information is converted into digital data commonly called 3D scan data or scan data. 3D scan data is a set of points. A point represents a location on a real object and contains the X, Y and Z coordinates. Numerous points con be used to describe a real object.

The Reverse Engineering strategy

The traditional design process is the creation of a final product through a chosen design process, such as concept designing or detailed designing used to create "something" from "nothing". The Reverse Design process can create valuable design data by capturing digitized shape information from a real object by using 3D scanning technologies, such as CMMs (Coordinate-Measurement Machine), laser scanners, structured light digitizer or industrial CT Scanning (Computed tomography). Design intent can be extracted from shape information.

The Reverse Modelling process is the process of creating the best 3D model from the scan data (Point Cloud or Mesh) generated in the Scan Data processing phase. These methods can be used solely or mixed with the other methods according to the desired output.

3D mesh modeling


Creating an optimized mesh from scan data


We can create the best mesh from scan data by cleaning defects, filling missing holes, modifying its shape, and optimizing mesh structure, according to the purpose of utilizing.

What is it useful for
  • Analyzing the model shape

  • Creating a reference prototype model by using Rapid Prptotyping technologies

Parametric feature modeling

Creating a 3d feature model based on the analyzed design intent and elements from 3D scan data


We can define features with parameters based on the analyzed design intent and elements from 3D scanned object. The created features can be reused, redefined, modified and translated by controlling parameters.

What is it useful for
  • Manufactoring a new product with enhanced functions based on existing product

  • Deplicating the target product which does not have a CAD model

    Analyzing design elements of another part of product

Fitting surface modelling

Creating a 3D freeform model based on the optimized mesh from 3D scan data


We can effectively and rapidly extract an accurate freeform surface from the shape of a 3D scanned object, by using various tools such as Auto surfacing, Mesh Fitting and Boundary fitting

What is it useful for
  • Creating outer forms of aesthetic model, such as car body and outer cover of consumer products

  • Manufacturing a new product based on the human body shape in the medical or dental fields

Hybrid modelling

Creating a complex 3D model from scan data


We can rapidly create a complex 3D feature model by mixing parameters features created by using Parametric Feature Modelling method and free-form surfaces created by using Fitting Surface Modelling method. The resulting 3D feature model can be reused, redefined, modified and translated by controlling parameters maintaining its outer free form shape.

What is it useful for
  • Designing a new product from mock-up or clay model

  • Designing a new product for assemply
