Merging ECAD and MCAD

Understanding parts lists, connecting processes.

Mechanics think in assemblies - Electrics in functions.

Parts lists are mirrors of these worlds - and this is where the misunderstanding begins. If you want to connect MCAD and ECAD, you need to understand the logic behind the systems.At DataSolid, we do just that - and create interfaces that not only transport data, but also enable communication.
ECAD-MCAD integration - basic problem

The basic problem: Different parts list logic

  • In MCAD (e.g. NX, Solid Edge)

    • Physical hierarchy: components in assemblies, across several levels
    • Articles appear once per structure level with a quantity specification

    • Example: Switch X is installed 5× → one entry, number 5

  • In ECAD (e.g. EPLAN®)

    • Item listing: each shoring individually with its own ComponentLocation

    • Structure is only created by filtering, e.g. according to function ("open door") or installation location

    • An article with 5 shoring → 5 entries, clearly about location and function

Result: Both systems depict reality correctly - but from completely different perspectives.

ECAD-MCAD integration - challenges

The challenge: Two systems, no common understanding

Range MCAD ECAD
Structure Physical tree structure Article list with filter structure
Multiple shoring An entry with quantity Multiple entries (per location/function)
Identification of individual parts Only logical via structure Directly via ComponentLocation
Point of view Geometric, mechanical Functional, electrotechnical
ECAD-MCAD integration - Solutions

Our solution: Creating understanding - connecting systems

  • Workshops & department alignment
    We synchronize MCAD and ECAD teams: understanding of the respective perspectives, conceptual worlds, structural logic.

  • Mapping the parts list logic
    Comparison of article understanding, structural concepts and parts list models

  • Interfaces with semantic depth
    We do not develop simple data transfer, but a "structurally intelligent" integration between ECAD and MCAD - for clean PLM data.

  • PLM integration with structural transformation
    Merging in Siemens Teamcenter: Components with position, quantity and location - traceable, consistent, process-capable.

ECAD-MCAD integration - Benefits

The concrete benefits for your company

  • Clear and consistent parts lists

  • Comprehensible allocation of shoring locations and functions

  • Better coordination between ECAD & MCAD - fewer queries

  • Future-proof PLM database for development, purchasing, documentation & service

  • Clear component identification, even in replacement cases

ECAD-MCAD integration - what we do

What we do in concrete terms

  • ECAD: EPLAN® (focused and deeply integrated)

  • MCAD: Siemens NX, Solid Edge

  • PLM target system: Siemens Teamcenter / Teamcenter X

Successful and secure CAD & PLM migration

... and fast too

ECAD - MCAD Merge parts lists

How does that work?
