Nova Trappe

What Nova Trappe does

Nova Trappe generates stairs with stringers and railings that follow real building practice — fast, exact, and ready to detail.

Key features

• Stairs with stringers — complex geometry in under 0.1s
• Code-aware railings (regulation spacing) with wood variants
• Stringer covers tread ends at the top; newels run past the stringer
• Knee-smoothing for clean direction changes along the run
• Adjustable rise/run and dimensions
