Automatic creepage and clearance analysis



Your challenges

Designers often resort to manual measurements and rough approximations without a software tool, which is not only time-consuming but also highly inaccurate and often leads to expensive production pipeline loops.

Our offer/approach

AutoCrear is a robust and efficient software for analyzing creepage and clearance. It uses advanced algorithms for handling complex metrics and can process large assemblies or PCB’s. It allows designers to detect and eliminate safety violations in the early design stage, optimizing the production of electric assemblies. AutoCrear is a standalone tool that can import data from any leading 3D-CAD-system. As a result, AutoCrear generates an automatic report, which can be supplemented additionally. The time saving for this process is enormous. ‍

Your advantages

  • Time saving: AutoCrear can save engineers significant time in measuring and documenting creepage and clearance paths on CAD designs, reducing the process from several days/weeks to just a few minutes/hours.
  • Cost saving: AutoCrear can save thousands of Euros per assembly in manual measurement and documentation costs, and also provides insurance against costly production loops or product recalls caused by missed violations in manual measurements.
  • Quality increase: AutoCrear enables engineers to design compact electric assemblies while ensuring compliance with industry regulations for creepage and clearance, avoiding the need for added safety distances between nets.
  • Safety: AutoCrear ensures accurate computation of creepage and clearance paths, avoiding the risk of unsafe product releases and recalls caused by missed violations in manual measurements.
  • Usage: AutoCrear can be obtained both as a standalone tool that supports popular CAD formats and as a plugin for PTC Creo Parametric.





Case study

Rockwell Automation Switzerland GmbH, based in Aarau, has been using AutoCrear since 2019 .

Developing ever smaller and more compact products is one of the strengths of Aarau-based Rockwell Automation Switzerland GmbH. It wants to reliably prevent flashovers or short circuits on switchgear. The company set up a test installation to find out which defects exist in the resulting product and how the AutoCrear software can help to identify them.

The conclusion: «In some places, the distances were not maintained and flashovers could have occurred. For this reason, our development department made some corrections to optimise the distance» says Werner Hebeisen, CAD system administrator at Rockwell Automation Switzerland GmbH.
