ECAD / MCAD Integration Software


ECAD / MCAD Integration for Electrical Design

E3.series interfaces with all leading MCAD tools to enable concurrent product design. Electrical engineers can collaborate with the mechanical design teams using the bi-directional interface of E3.series E3.3DRoutingBridge. The flattening options in E3.series simplify using a 3D harness model to drive formboard drawings for manufacturing.

The versatile workflow helps electrical teams work independently or collaboratively to match project requirements. E3.series supports industry-standard cable and harnesses information-sharing formats to ensure smooth communication. Advanced 3D conversion tools and analysis options help utilize the strengths of MCAD design systems to streamline the electrical design.

3D Transformer

Transforming Collaboration between ECAD and MCAD

E3.3DTransformer improves the MCAD collaboration process for ECAD and MCAD teams. It is a single tool supporting various file formats to revolutionize the transformation of 3D MCAD data into a comprehensive E/E topology model. ​

The support of native files from leading MCAD platforms and standard industry formats eliminates the need for time-consuming back and forth between ECAD and MCAD teams.

Efficient Harness Manufacturing through 3D to 2D Conversion

The E3.HarnessFlattening tool analyzes the 3D geometric data from MCAD systems to help designers automatically create a formboard manufacturing layout. The harness flattening process accepts supported inputs directly from MCAD applications through E3.3DRoutingBridge and E3.3DTransformer. The ability to automatically or manually select the harness backbone drives the formboard structure. The elimination of manual recreation of harness structure simplified the overall MCAD to ECAD process.

  • Electrical and Mechanical Collaboration
  • Automatic and manual harness backbone selection
  • Supports cable clips and protection
  • Automatic formboard creation


The 3D geometric data extracted from supported MCAD systems forms the input for the E3.HarnessFlattening tool. The harness is then visualized in 3D to determine the most appropriate backbone. The harness bundles’ diameter drives the harness backbone’s automatic selection. After confirming the backbone selection, the software flattens the harness with all branches emitting from the backbone.

Once flattened, the harness data is then imported into E3.formboard. The import includes segment lengths, connections, wires, connectors, splices, protection, and clips. The connectors automatically associate with the logical schematics, and wires automatically route in the harness if the original schematic source was E3.series.
