Our Journey with PMI – It is only just beginning!


Getting Started

If you are already using NX it only takes one person to

turn your team onto PMI: “The Explorer”

Why should we support and encourage the explorer?


Getting Started

Be the Visionary

• Do you?

• Want to deliver 2D faster

• Struggle to communicate

design intent

• Imagine future = 2D prints


Getting Started

1. NX (with PMI add-on)

2. The Explorer

3. The Visionary

So what has our journey taught us?

The Journey

PMI data is “model view”

dependent

Creating PMI objects:

First, make the desired model view

the “Work View”


The Journey

PMI created in one view can easily

be displayed in any or all views;

(“display instances”)

Must always reside in at least one

view


The Journey

PMI tool does not

like grabbing points

on splines


The Journey

By creating a

lightweight section

view, you can

dimension the edge

created


The Journey

You can then move the PMI

dimension to any view that you

wish


The Journey

One Challenge and One Success


The Journey

One Challenge…


The Journey

CAD objects checked into Windchill are viewed in CreoView

• PMI data does not show up

MCOSMOS (CMM tool) can import CAD files to facilitate

automated inspections

• PMI data does not show up

Standard file exports? .STEP…

• PMI “disappears” during export

Common denominator: .STEP format


#PLMCONX • www.plmworld.org






The Journey

In summary

• CreoView – PMI is lost

• MCOSMOS – PMI is lost (potential exists for native NX import)

• .STEP file – PMI is lost (sort of)

Potential Solution: JT file format


The Journey

… and One Success


The Journey

SONOS ME closed a gap in

their workflow with the

Industrial Design team


The Results

The Future

Using PMI:

• Streamline the outsourcing of 2D

• Capture manufacturing capabilities real time while

reviewing parts with manufacturing partners

Allowing cross-functional team members to interrogate

the PMI data in our managed environment

So what’s next?

Scenario: conceptual design with notes capturing design

intent and requirements


Scenario: conceptual design; live dimensions, notes, URL

notes, associated objects


Scenario: detailed product design; live dims, lightweight

section views, part/material labels, assembly filters,

associated objects, display preferences


Scenario: drawing views with important product notes and

manufacturing information created by the designer


Scenario: convert sketch dimensions to PMI; edit key part

parameters on the fly, outside of the sketch

Creative Application of PMI, NX Open, and Advanced Simulation:

Workflow for Automation • Convert Catia part with PMI to JT file

• Import JT file with PMI into NX

• Transform PMI information to CAE

attributes (specific syntax) • Automatically mesh component

• Apply load and boundary conditions

using CAE attributes (specific syntax

from PMI)

• Run structural simulation • Generate result JT files

• Generate word report

NX Sim and Fem files can be reopened

and modified (mesh, loads, boundary

conditions)

Readily expandable capability
