Introduction to Creo Wire Harness:
Creo Wire Harness is a specialized tool within PTC Creo Parametric that allows engineers to design and model wire and cable harnesses in 3D. It helps create and manage the electrical routing of wires, cables, connectors, and other components in complex assemblies.
Creating library for wire harness creation. downloading step files and saving as part file.
Learn to create a splice in Creo Parametric by sketching circles, applying dimensions, extruding, and establishing a centered coordinate system, then save to the Udemy wire harness folder.
Purpose of Creating Coordinate Systems and Axes in Wire Harness Routing:
Coordinate Systems:
Define precise connector placement and orientation.
Act as reference points for routing wires.
Axes:
Ensure accurate alignment along cylindrical or linear features.
Provide routing paths for wires around circular components.
Develop coordinate systems and axes on connector cavities and terminals in Creo Parametric to define wire paths, ensure the z axis points outward, and prepare components for mating.
Create a sheet metal base model in creo parametric by sketching a rectangle on the front plane, applying thickness, and adding flanges to host wire harness connectors.
Create a cylindrical wire harness label in Creo Parametric with a 6 mm outer diameter, a 5 mm inner circle, and a 20 mm length for identification and BOM integration.
Learn to assemble multiple connectors on sheet metal in Creo Parametric, align faces, set coordinate references, adjust positions and colors, and verify wire entry and overall harness assembly.
Create a sheet metal base model assembly and wire harness by adding connectors, activating cabling, and creating a harness part named wire_harness, then align and fix connectors and save.
Designate connectors for a Creo Parametric wire harness by assigning entry ports and coordinates, and configure cabling parameters to ensure proper wire routing.
Master the Creo Parametric wire harness routing workflow by creating and joining networks across blue, yellow, and red connectors, adjusting locations, ensuring continuity, and managing sheet metal interference.
Cross check the entry locations of all connectors in the wire harness to ensure they are non-editable before creating the flatten view.
Demonstrates assembling a splice in a wire harness. Load a slice from the library, align with the label, and route a network between the slice coordinate and a location.
Assemble the coroplast covering onto the wire harness in Creo Parametric, using axis and coordinate placement and reference alignment to enable generation of a parametric bill of materials.
Resolve interference errors in Creo Parametric wire harness by adjusting views and placements of splice, label, and coroplast, editing definitions, and regenerating until the network fits the base model.
Learn to delete a cable portion in a Creo Parametric wire harness network by creating coordinates and aligning to connector axes for proper wire routing.
Master creating flattened and manufacturing views for wire harnesses in Creo Parametric by building flattening layouts, setting bend radii, using auto fan, and reorienting isometric views.
Create a flattening layout for the wire harness by adjusting branch angles, radii, and coordinates, then assemble components and resolve splice placement in the flattened view.
Resolve flattening errors in a Creo Parametric wire harness by adjusting connector orientation, segment lengths, and coordinates, then regenerate and flatten components to achieve proper wire connections.
Learn to save and verify flat view files for a wire harness, set a working directory, and prepare drawings by assembling, disassembling, and regenerating in the project folder.
Create a drawing from a flat harness assembly in this Creo Parametric wire harness course lecture, then add models, insert harness parts, set views, and annotate designations.
Learn to create a parametric, automatically generated bill of materials for drawings in Creo Parametric. Organize serial numbers, part numbers, descriptions, and quantities in a table using a repeat region.
Learn to create and format dimensions for a wire harness in Creo Parametric, using ordinate and normal dimensions, control lines, jogs, and alignment for zero-decimal outputs.
Learn to create notes for drawings and delta symbols in Creo Parametric harness design, including unattached notes, delta symbol creation, and symbol customization.
Place and adjust an isometric view in the drawing, then create partial and detail views from assemblies or connectors using reorient and spline drawing.
Course content
Wire and Cable Component Library
Access and manage wire, cable, and connector components from predefined libraries to streamline the design process.
Wire Routing
Route: Create the paths for wires and cables in 3D space by selecting start and end points for each wire or cable.
Auto Route: Automatically route wires and cables based on available paths and component placement.
Cable Routing
Route Cable: Similar to wire routing, but for multi-conductor cables. Helps define the path of cables with multiple conductors.
Splice and Branching
Create Splice: Add splices to wire or cable paths where wires/cables connect or split.
Create Branch: Design branching points for wires or cables that need to diverge or join.
Harness Flattening
Flatten: Convert 3D wire harness designs into 2D flattened views, useful for creating manufacturing drawings and layouts.
Flat Pattern: Automatically flatten wire harnesses based on the 3D geometry and routing.
Harness Assembly
Create Harness Assembly: Define and manage the complete assembly structure of the wire harness, including all components and paths.
Assemblies: Assemble multiple wire harnesses or subassemblies in a larger assembly context.
Connector Insertion
Insert Connector: Place connectors and define their type, orientation, and connection points for wire routing.
Part Modeling for Wire Harness
Model Components: Create or modify components such as connectors, junctions, or clips that are part of the wire harness design.
Create New Part: Add new components to the wire harness library and design new parts as required.
Electrical Connection Management
Define Electrical Connections: Specify how components are electrically connected, including defining pin numbers, terminals, and wire types.
Documentation and BOM Generation
Bill of Materials (BOM): Automatically generate BOMs that list all components, wires, and cables used in the harness design.
Export to Drawing: Generate detailed drawings for manufacturing, including annotations and dimensions specific to wire harness designs.
Harness Report Generation
Generate Reports: Automatically generate reports detailing the design, wiring lengths, and assembly instructions.
