1. INTRODUCTION TO PARAMETRIC MODELING : Origin

Specs :T°, P, C

Presentation

Calculation: D mini, Valve XXX

- Time consuming

- Lack of flexibility

- Unpleasant routine job for designers

How to accelerate the process?

Manual Input to renew at each spec modification

PARAMETRIC MODELING

Specs :T°, P, C

Calculation: D mini, Valve XXX

- Transform the specs, calculation, expert rules into parameters and relation included in 3D modeler

- Construction of a parameter driven geometry

-The Geometry is directly linked to functionnal parameters, and automatically updated

Geometry

- Time saving

- Less repetitive work

1. INTRODUCTION TO PARAMETRIC MODELING : Principles

PARAMETRIC MODELING

External diameter of shaft D Bearing Length: L L=1.5D

Non parametric: 44 sec- 4 dimensions to modify- Repetitive operations

Parametric: 13 sec- 1 parameter to modify

1. INTRODUCTION TO PARAMETRIC MODELING : Example

2. BASIC FUNCTIONS

PARAMETRIC MODELING

2. BASIC FUNCTIONS : Parameters and formula

Parameters:

- Has a name, dimension, and value

- Can be anything: mm, T°, MPa, s,

- Can drive or be driven

- Can be inputted or picked up from a list

- Can be limited to a range

Available in any workshop

PARAMETRIC MODELING

- Formulas

- Will allow to create a mathematical link between one or several input parameters, and a output one

- Only allow to create continuous links

- Insert Knowledge, expert rules in an assembly

2. BASIC FUNCTIONS : Parameters and formula

PARAMETRIC MODELING

Example of the shaft and bearing:

We want to drive it from “functional parameters” such as torque, safety coefficient

PARAMETRIC MODELING

3. ADVANCED FUNCTIONS: knowledgware

Knowledge Advisor: Most of knowledge tools,

Product Engineering Optimizer: Optimisation

PARAMETRIC MODELING

3. ADVANCED FUNCTIONS: Knowledge Advisor

Rules:

- Allow to create non continuous actions

- Synchronus (relaunched each time an entry parameter is modified)

- Several outputs

PARAMETRIC MODELING

Reaction and actions:

- Like a rule but Asynchronuous (Launch action when a specified parameter is modified)

- Possibility to couple short script etc

3. ADVANCED FUNCTIONS: Knowledge Advisor

PARAMETRIC MODELING

Check:

- similar to the rule, but just giving an informationif D>30mm

3. ADVANCED FUNCTIONS : Knowledge Advisor

PARAMETRIC MODELING

Optimizations:

- Possibility to include an optimization inside the model

- You can then couple it to a reaction so that it is launched any time a specific value is changed

3. ADVANCED FUNCTIONS: Product Engineering Optimizer

4. PARAMETRIC AND SMARTEAM

PARAMETRIC MODELING

- No problem when creating parameters, formulas, copying sketches, inside a Part.

- When creating formulas, copying parameters, sketches between parts, has to be outside the context of an assembly.

- Each part has to be open in a different window, and not being open in an assembly in another window

Preliminary

- No Replace to latest

PARAMETRIC MODELING

- To buil a parametric assembly, always use a skeleton

- Put the pilot parameters inside the skeleton

- Use it as knowledge container to distribute the parameters to different parts
