CATIA V5 Tip: Adding Balloon Callouts to an Assembly Drawing

By Trisha West

In this video, Technical Trainer Trisha West demonstrates how to add balloon callouts to an assembly drawing which requires generating the numbering convention, Bill of Material (BOM), and drawing balloons. Also included in this video is how to place the Bill of Material chart in the drawing using two methods: placing BOM in sheet background and also in the working view.

 

 

 

Creating a Manikin Simulation in CATIA V5

By Trisha West

 

In this video, Technical Trainer Trisha West shows the two methods of creating a manikin motion file: a simulation using saved manikin postures in a catalog, and creating a track with a manikin object.

Creo Parametric Tip: A Design Consideration When Creating a Flat Pattern for a Complex Harness

By Natasha Reaves

 

This question was originally asked by a former student who attend the Creo Parametric Cable and Harness Design course and was answered by the class instructor. 

 

Student's Question:

What is the best method of creating a flat pattern for a complex harness? Even when I try manual, there is still a branch that won’t let me select it for a start point.

 

Instructor's Answer:

A possible solution to creating your flat harness linked to a complex assembly is to use a sub-harness.

In your harness part, you can create a sub-harness or sub-harnesses. A sub-harness is a portion of a harness (and not a separate part file); It is visible in the model tree in the harness Footer area. Using this you can possibly break up the wire features in “groups” that can be managed a little easier in the flattened harness model.

You can use all of the entities available for harnesses when working with sub-harnesses, but Creo allows you to also work with sub-harnesses separately in Harness Manufacturing mode.

(SIDENOTE: Harness-MFG module is used to create flattened harnesses from 3D harness parts).

To set the default sub-harness, use the MODIFY HARNESS icon located in the Harness group in Cabling mode. Then select the harness that includes the sub-harness you wish to set as the default. You can then click on Set Default and select the desired sub-harness.

Creo Parametric: An Overview of the Electromechanical Cabling Design Process

By Natasha Reaves

 

In the Creo Parametric Cable and Harness Design course, you will learn how to route electrical harnesses with and without schematic diagram information. Additionally, you will learn how to create flattened harnesses for manufacturing and how to document harness designs by creating flattened harness drawings that include BOM tables and wire list information.

In the Creo Schematics course, you will gain a full understanding of the schematic design process used to provide schematic data for the creation of electrical harness assemblies in Creo Parametric.

 

A process overview of the electromechanical cabling design process using Creo Parametric is shown below.

 

The following process outline describes how Creo Parametric is intended to be used to design electromechanical cabling systems.

1. Decide which cabling entities will be routed to various electromechanical devices in the assembly.

2. Using Creo Schematics, create a 2D schematic to represent the logical connectivity between the cabling entities and their respective electromechanical devices. 

3. In Cabling mode, create a realistic 3D assembly by routing cable geometry throughout the assembly. To expedite the design process, logical connectivity and parameters that are defined in Creo Schematics can be used in Cabling mode. In situations where it is not feasible to create a 2D schematic using Creo Schematics, other methods can be used to create a 3D cabling assembly using the logical reference method of defining cabling parameters and features.

Creo Parametric allows you to import logical reference information using the following files:

• Creo Schematics
• PTC Neutral file
• Mentor Graphics File

4. Using HARNESS-MFG mode, create a flattened harness to simulate laying out wire and cable harness geometry on a nail-board.

5. Create a 2D drawing to document the flattened harness for manufacturing. Use Pro/Report to create a customized bill of material and wire list. Drawings can also be created for the routed 3D assemblies.
