Welcome to the DMU Space Engineering Assistant User's Guide. This guide is intended for users who need to become quickly familiar with the DMU Space Engineering product Version 5 Solution.

This overview provides the following information:

DMU Space Engineering Assistant in a Nutshell

DMU Space Engineering Assistant shortens design cycle time in concurrent environment through the capability it gives the designers to check the consistency of their design with the data stored in ENOVIA V5 while they are working. This is done thanks to interference analysis piloted by Knowledgeware rules allowing best practices compliance at the company level. Interference analysis results can then be stored in ENOVIA V5.

Thus, DMU Space Engineering Assistant  fits the needs of designers working in a collaborative environment, in industries dealing with large assemblies (shipbuilding, automotive, aerospace, etc.).


DMU Space Engineering Assistant checks the consistency of a design with the data stored in ENOVIA V5 according to pre-defined clash analysis rules allowing shorter design cycle time.

  • Defines knowledgeware rules that will pilot clash computation
    • Specifies the computation type (clearance, contact, clash) and the components on which the clash computation must be applied 
    • User/company benefits : automation, productivity gains, best practices/standardization, more accurate and relevant clash results
  • Performs interference analysis according to predefined clash rules between in-session component (s) and components stored in ENOVIA V5.
    • Interference analysis computation is done on a dedicated server
    • This interference analysis occurs when a component is created or modified in CATIA V5
    • This interference analysis occurs when a set of components are moved in CATIA V5
    • User benefits : 
      • while working a designer can check the consistency of his design with the stored data in ENOVIA V5
      • productivity and shorter design cycle in concurrent environment
  • Stores the interference analysis results in ENOVIA V5
    • Browses the interference analysis results and manage conflicts
      • The user can choose the status of conflicts (irrelevant, relevant)
      • Dedicated browser presenting the interference analysis results
      • The user can also comment conflicts and filter them
    • Loads from ENOVIA V5 the components interfering with the in-session components and the relevant interference analysis results
    • Stores automatically interference analysis results when storing the in-session component in ENOVIA V5
    • Interferences are detected between user sessions data and any part effective in any configuration

Before Reading this Guide

Before reading this guide, you should be familiar with basic ENOVIA and CATIA Version 5 concepts. Therefore, we recommend that you read the Infrastructure User's Guide that describes generic capabilities common to all Version 5 products. It also describes the general layout of V5 and the interoperability between workbenches.The Engineering Life Cycle User's Guide may prove useful to understand ENOVIA cocnepts and learn how to perform basic operations in ENOVIA V5

You may also like to read the following complementary product guides, for which the appropriate license is required:

  • Knowledge Expert User's Guide (containing information necessary to create Expert rules)
  • DMU Space Analysis User's Guide
