Feature Generation Evolution¶

v3.60 Approach¶

Separate modules: weldconn, chamfer, dowels, bolt, etc.
Feature logic embedded in drawing modules
Some redundancy between features

v7.0 Approach¶

Unified feature.lsp (42.8 KB)
- Centralized feature generation
- Common feature infrastructure
- Extensible architecture
Specialized modules call into feature system
Less duplication, more consistent

Performance & Efficiency¶
