NEST – Nested Elements and System Tolerancing
(Premium & Enterprise)
• Introduces a visual, guided workflow for
optomechanical tolerancing in sequential
systems
• Define nested element groups with
automatic insertion of Coordinate Breaks
and tolerance operands
• Smart pivot presets calculate correct pivot
locations for tilt and decenter tolerances
• Real-time layout updates visualize
mechanical structure and pivot behavior
• Supports off-axis and reflective systems,
reducing setup effort and improving
tolerancing confidence
Faster optomechanical tolerancing
with fewer setup errors
