Pros and Cons of History-Based and History-Free Modeling
History-Based Modeling Benefits
• Mature CAD products with many
die-design-specific extensions
• Excellent for design optimization
and automation
• Develop reconfigurable intelligent
platforms, and reuse
• Inherent feature-to-feature
associativity (part > strip > die)
• Many designers with experience in
one or more of these tools
• Growing direct-editing capabilities
for improved flexibility
Challenges
• Long learning curve, can be complex
• Data exchange at the history or feature level
• Must plan ahead and follow good modeling practices
• Complex dies can be overwhelming to the system
• Large file size and potential slow performance
History-Free Modeling Benefits
• Relatively short learning curve,
easy to learn
• Many ways to create and edit
geometry
• Work with geometry from any
source
• Independent from how geometry is
created
• Can work with STEP and IGES
data as native data
• Flexibility in capturing design
intent
• 70- to 90-percent smaller files
Challenges
• Many immature representations of direct modeling on the market
• Few die-design-specific extensions
• Less optimized for design
optimization and automation
• No parent/child relationship, i.e.
no inherent feature-to-feature associativity
