Configure parametric Price Engines for automated area and perimeter window calculations

1 min read Updated 2026-08-28 WindoorERP 19.0

What this does

Configures advanced mathematical pricing engines that calculate window and facade prices based on dynamic surface area (m²), frame perimeter (linear meters), glass weight, and hardware unit counts.

Before you start

  • Parametric Estimation module installed.

Steps

Parametric price engines catalog list

Price engine formula and threshold editor

Important

Minimum area thresholds protect fabrication labor costs on small, labor-intensive ventilation windows.

  1. 01
    Open Sales › Configuration › Price Engines.
  2. 02
    Define formula rules: link base extrusion profile rates ($/lm) with glass unit rates ($/m²).
  3. 03
    Set minimum billing area thresholds (e.g. small bathroom windows < 1.0 m² billed at minimum 1.0 m² rate).
  4. 04
    Bind the price engine to specific window system series (e.g. Structural Curtain Wall Series 50).

Common mistakes

  • Not accounting for structural steel reinforcement weights in tall curtain wall elevation formulas.
  • Leaving scrap percentage allowances at 0% inside custom price engine scripts.
