Commercial Steel Door Configurator
Hollow-metal door configurator: single or pair, gauge, core, vision lites and hardware — hinge counts by height rule, conditional panic bars, live 3D, and a table-driven price.
Hydraulic Cylinder Configurator v1.2
Engineer-to-order hydraulic cylinder: bore, stroke and pressure drive rod buckling, wall thickness and seal selection — and the mounting style physically reconfigures the 3D model. (v1.2: real mass-based costing — quote model on page 2, margin health indicator, costed BOM quote sheet)
Keltec Filtration Configurator
Compressed-air filtration on KELTEC Technolab published data: train sizing with pressure correction and smallest-fit housing selection, plus a custom air-oil separator spec builder with live 3D and nearest-standard-part match.
Conveyor Section Designer v1.2
One complete belt conveyor section — rollers auto-place per pitch, the IEC motor is selected live, and the 3D scene rebuilds as you stretch it. (v1.2: belt+idler mass, cos δ, acceleration term, service-factor motor sizing, two-sided utilization)
Conveyor Section Designer v1.1
One complete belt conveyor section — rollers auto-place per pitch, the IEC motor is selected live, and the 3D scene rebuilds as you stretch it. (v1.1: stringers centered under the belt)
Conveyor Section Designer
One complete belt conveyor section — rollers auto-place per pitch, the IEC motor is selected live, and the 3D scene rebuilds as you stretch it.
Ladder v2
