Pillar 1: The Engineering Toolbox (560+ Interactive Calculators)

Instant, zero-friction formulas running purely in your browser — no accounts, no installations

Design drafting often halts because an engineer needs to quickly verify a shaft torque, check hydraulic cylinder sizing, calculate beam deflection, or determine concrete mix proportions. CADGuide.tools provides a curated suite of specialized engineering calculators built with verified engineering standards (ASME, ISO, Eurocodes, AISC).

⚙️ Mechanical & Manufacturing Tools

Essential calculators for powertrain sizing, machining parameters, and mechanical assembly tolerances:

Gear Ratio & Output Speed — Tooth counts, pitch diameters, and RPM Launch ↗
CNC Speeds & Feeds — Surface feet per minute, chip load, spindle feed Launch ↗
Bolt Torque & Preload — Clamping force, proof stress, K-factor friction Launch ↗
Thermal Expansion & Fit — Linear expansion coefficient and press fits Launch ↗

🌊 Fluids, Hydraulics & Thermodynamics

Sizing valves, fluid lines, cylinder pistons, and checking thermodynamic flow states:

Hydraulic Cylinder Force — Bore diameter, stroke, extend/retract push Launch ↗
Reynolds Number — Laminar vs turbulent flow regime analysis Launch ↗
Pipe Head Loss & Friction — Darcy-Weisbach & Hazen-Williams drop Launch ↗
Pressure Vessel Wall Sizing — ASME Section VIII thin/thick wall stress Launch ↗

🏗️ Structural, Civil & AEC Utilities

Cross-section properties, material quantities, and beam load calculations:

Section Modulus & Moment of Inertia — I, C, Rectangular, Tube sections Launch ↗
Concrete Volume & Mix Proportions — Bags, gravel, sand batching Launch ↗
Beam Deflection & Bending — Point & uniform load maximum deflection Launch ↗
Retaining Wall Earth Pressure — Rankine & Coulomb lateral forces Launch ↗

⚡ Electrical, Power & Controls

Essential ECAD and control-panel calculations for wiring, breakers, and drops:

Ohm's Law & Power Law — Voltage, current, resistance, dissipation (Watts) Launch ↗
Wire Gauge (AWG) & Voltage Drop — Resistance per foot & length drop Launch ↗
3-Phase Power & Motor Current — kVA, kW, power factor, line amps Launch ↗
Transformer Sizing & Derating — Inrush currents, winding heat limits Launch ↗

Pillar 2: Independent CAD & BIM Directory & Comparison

Cut through vendor marketing spin with verifiable technical specifications and pricing structures

Software licensing has become increasingly convoluted with named-user subscriptions, cloud token credits, and fragmented feature tiers. CADGuide.tools maintains an objective software directory comparing the world's most trusted engineering platforms across real engineering metrics.
