Reverse Engineering リバースエンジニアリング

Reverse Engineering

A viable method of creating a virtual model of an existing part. Reverse engineering is the art of recreating the original design of a component.

Note:Data at any stage can be provided upon request.
We also accept data construction from the provision of scan data

From development to design, prototyping, and mass production, Yasojima Proceed aims to provide services that are useful to customers in all processes of product development.

  • Reverse engineering based on scan data.
  • In-house prototyping by 3D Printing.
  • Specifying areas which may require design modification, by comparing and verifying 3D CAD data with actual product scan data.

 Yasojima Proceed’s total service meets all your 3D printing needs. Leave it up to the experts to ensure you get the most benefit from this versatile technology.

Yasojima Proceed’s reverse engineering experts will answer paramount questions in determining the successful path of data output.

As it can speed up development and cut production costs, reverse engineering is paramount to multiple industries such as manufacturing, automotive, aerospace, and in a wider sense, even areas such as medical. With the tools and vast experience necessary to provide reverse engineering services for many different components, parts, and assemblies, Yasojima Proceed can streamline your project.

Data variations

3D modelSurface unevennessError with measured dataAdvantages & disadvantages

STL/Voxel data

  • Almost the same with measured data
  • Surface is fairly uneven



Most accurate to the scan
STL file is available in a 3D printable format
Making design changes can be difficult
Holes and other features may not be perfect

Generated surface automatically using point cloud

  • Slightly uneven surface
  • Editable data on 3D CAD
  • Surface “patches” are random



Accurate to the scan
Output as CAD data (IGES, STEP, …)
Holes and other features may not be perfect.
Surface “patches” are random

Surface data using point cloud

  • Give priority to measurement data and edit sections neatly
  • Mostly used in free form surface such as human body, propeller, etc.



Good quality surface data will be generated by manual work
Output in CAD data (IGES, STEP, …)
Difficult to adjust and create face edges
Poor quality of data created based on geometry

Surface data referred to point cloud

  • Use only a portion of measurement data
  • Create data to be geometric



Almost normal CAD data quality
Complete as CAD data (IGES, STEP, …)
Data creation requires design skills

In reverse engineering, the method of creating surface data may change depending on the location even for the same part. In doing so, we will interweave the above methods to create surfaces in a composite manner.
