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
