10+ tray brands incl. AFCMETAL, OBO, EAE, custom
Auto-expand width to target fill (NEMA VE-1 / IEC area + width)
Multi-tier perforated / ladder / solid / trunk / mesh

Support Statics Support static analysis

Bracket · Binrack · Threaded Rod

Support Static Analysis

Stress, deflection and SWL anchor check for every common support configuration — per-tier breakdown and full bolt-by-bolt BOM.

Span, profile (41×41×2 mm strut, 41×62, custom), tier load
M = q·a·(2L−a)/8 partial UDL correction
Bolt count: n = 2 × tiers × sides — full BOM
Auto SWL anchor check (concrete/steel drop-in / wedge)
Deflection limit L/200 indicator

Seismic Design

ASCE 7-22 · Eurocode 8

Seismic Design Analysis

Anchor & bracing verification for non-structural components. Two-spectrum support: US Fp formulation and European EN 1998-1 Type 1 / Type 2.

Fp = 0.4 · ap · Sds · Wp · (1 + 2z/h) / (Rp/Ip)
ap = 2.5, Rp = 6.0 for cable tray (ASCE 7-22)
EN 1998-1 Tablo 3.4 horizontal/vertical spectrum
Anchor pull-out, shear and combined check
Per-bracket transverse and longitudinal bracing

Cable Pulling Cable pulling analysis

IEEE 1185 · sequential capstan

Cable Pulling Analysis

Tension and sidewall pressure along the entire routing — segment by segment, not the over-conservative single-equation shortcut.

T = μ·W·g·L · ∏ e^(μ·θᵢ) + W·g·h (segmental)
Sidewall limit 7300 N/m (IEEE 1185)
Weight correction factor (IEEE 1185 §6.4)
Friction decay model for lubricated pulls
Trefoil and single-core grouped configurations

Thermal & Fire Thermal expansion

EN 1993-1-2 · DIN 4102-12

Thermal Expansion & Fire

Linear and exponential expansion, fire-degraded steel modulus — both the gap-sizing problem and the structural reduction problem.

Linear ΔL = α·L·ΔT for steel and aluminium tray
Expansion joint spacing recommendation
Steel fire reduction ky / kE (EN 1993-1-2 Tablo 3.1)
DIN 4102-12 fire rating compatibility check

Route Designer

FreeCAD-style · DXF

Route Designer (CAD)

Click-to-place routing with rubber-band preview, ortho mode, snap grid and IEC 60617 symbol library — drawn natively, no licensed dependency.

F8 Ortho · G Grid · Del Undo · Esc Finish
AutoCAD-style UCS origin axes + crosshair cursor
DXF import & export via ezdxf
IEC 60617 symbol library (original Python canvas code)
Tray width from calculation auto-applied to route

Reports & Audit A4 PDF report

PDF · Excel · DXF · QR

Reports & Audit Trail

Every calculation produces a sign-off-ready deliverable with QR-verified signature, project metadata and clause-by-clause cite list.

A4 PDF report (ReportLab) with cover, table of contents
Excel BOM export with bracket-level breakdown
DXF support drawing (ezdxf)
QR code signature for downstream verification
Full audit trail (audit_log.py) — who, when, what

More inside the box

Tools that mature engineers actually want.

All bundled. No add-on packs. No paywalls inside the app.

Conduit Fill (NEC + IEC 61386)

Single-cable and group-cable conduit fill against NEC Chapter 9 Tables 4 & 5 and IEC 61386 series — area, dimension and bend-radius checks.

Bend Radius Validator

Per-cable minimum bend radius from manufacturer datasheet, MV cable factor multipliers, route geometry check.

Current Check (Caneco-style)

Reactive Applied Factors panel — change ambient temp, method, tiers or insulation and watch derating, voltage drop and load bar update live.

Batch Calculation

Run hundreds of sections in one pass from an Excel circuit list. Console output, progress bar, per-row diff report.

Brand Library
