WAVE Geometry Linker – What are the benefits? Full parametric integration of part design data into tooling design process Flexible management of linking process “Geometry safe” method Improved performance (smaller individual files) No additional license required Helps even with “challenging part geometry”

Problem Geometry – How to deal with it? Well defined and simplified parting lines With clean part geometry, even non-parametric data integration can proceed WAVE management is critical to preserve tooling data integrity – breaking and re-establishing WAVE links, delayed updates Topology problems must be fixed – clean topology is a MUST for math data integrity
