Challenge – I am not sure if my client is configured

optimally for working with large

assemblies

Description – Client inspector tool to evaluate client

systems

Benefit – Tools to help with proper client

configuration

– Can run remotely by administrators for

multi-user support

Challenge – Creo does not provide out of box

templates to support Simplified

Representations

Description – Develop set of company standard

templates to support assemblies and

parts

– Distribute and utilize in a common

location

– Layers, Views and Representations

Benefit – All users can utilize during model creation

– All users will be able to utilize during

retrieval

Design Templates

5

Challenge – Drawing objects reference the Master

when stored within PDM

– Even though templates are built for

Assemblies and Parts, Drawing creation

and retrieval still download Master Rep

Description – PTC provided Drawing template views

use Master Representation

– Develop template that supports your

company standard view representations

– Remove model master

Benefit – Using drawing representation, only

retrieved models supporting rep are

retrieved**

Challenge – Creo’s Graphics / Geometry

representations still require the master to

be downloaded to workspace

Description – Creo Parametric 1.0 provides the ability

to use Creo View lightweight graphics

Benefit – Provides quick viewing

– Performance depends on presence of

thumbnail and their quality

– Can be used within or outside of a

Windchill environment

Challenge – Want to collect objects in assembly around

component requiring change regardless of

assembly structure without downloading the

top level

Description – Windchill 10 provides the ability to create

External Simplified Representation using

viewables

Benefit – Uses lightweight viewables in “commonspace”

workspace with no need to download master

representations locally

– Uses server side template to define initial

content

– Requires only the top level object in workspace

initially

Challenge

– Completing interactive interference

calculations in the parametric

environment is time consuming

Description – Creo 1.0 View provides improved tools

to complete interactive calculations

– Interference and Clearance

– Publishing rules control accuracy of OL

to master

Benefit – Allows usage of the lightweight

graphics information

– Delivers reports on interferences found

Challenge – Completing interactive interference

calculations in the parametric environment

is time consuming

Description – Windchill 10 provides the ability to batch

process interferences included the

development of reports

– Record and manage clash jobs in the database

– Relay and resolve results of clash analysis with automated reporting and communications

Benefit – Systematically identify potential component

interference issues early with desktop and Windchill-based high performance clash detection

Challenge – Want to take advantage of product

structures when assembling

Description – Windchill 10 provides the ability create

assemblies that include unplaced

components using pre-defined templates

and existing designs

Benefit – Has minimal requirements for only

Commonspace Workspace interaction for

background processing

– Faster development of unplaced

component assemblies supporting

modular product development
