Case Study - Bonfiglioli

From Engineering Drawing Conversions to a Design Back Office

Delivering high satisfaction levels over multiple assignments at Bonfiglioli, enables Changepond to transition from an engineering conversion only provider to a high quality low cost extended design back office.


Bonfiglioli has most of its engineering drawings in legacy 2D (two dimension) form. The primary intent of the project with Changepond was to convert these drawings into 3D (three dimension) models so that auto assembly based product modifications and product data management could be handled more effectively. The transition process needed to ensure that all Bonfiglioli’s internal standards for design representation were understood and implemented with the transition.

The Solution and Outcome

Changepond executed a pilot project wherein Bonfiglioli’s 2D drawings were converted to 3D models. The conversion involved updation of details of materials, tolerances, heat treatments, finish process, manufacturing notes and title blocks as per the standards used by Bonfiglioli. Data regarding gear specifications were updated from IPAR, Bonfiglioli’s internal software for calculating gear data with cutter specifications. The 3D models were represented in standard outputs like IGES, STEP, PARASOLID, DXF depending on the standards followed by their Customers.

Cast moldings were represented in such a way that they could be used for future mould making. The 3D models were also very useful in making product modifications easily. Product Data Management was also simplified since data could be extracted from the 3D models and exported to the Product Data Management System.

Changepond delivered the project within the planned timeframe.

Over 20 Changepond engineers continue to provide services to Bonfiglioli and they are organized in the following manner:

Technical Specifications Team

Determines technical specifications to be used during modeling and drawing creation.

Design Team

Performs the 3D modeling and 2D detail manufacturing drawing creation work.

Process/Quality Assurance Team

Executes quality assurance to certify the data. This team also checks for the technical specification conformance.


Bonfiglioli was able to execute a highly design intensive solution, with high quality, speed and accuracy at much lower costs than locally available solutions. The Changepond team scaled to translate this benefit not only for conversion related areas but also a number of design related areas, thereby becoming a high quality yet low cost extended design back office.
