Infradigital CAD — Highway Engineering & BIM Automation Suite
Infradigital CAD (also known as Infra Digital CAD) delivers multi-standard civil engineering software calculators and Civil 3D automation tools. Fully aligned with Ethiopian Road Standards (ERA 2013 & AACRA) and International AASHTO & FHWA Guidelines.
Civil Engineering Tool Catalog
Select a tool to format Civil 3D data, design pavements, or size drainage structures
Folder Structure Generator
Generate compliant drawing submission structures sequentially. Enforces structure naming and exports as ZIP.
Horizontal Alignment Formatter
Convert raw Civil 3D horizontal curve exports into PC → PI → PT formatted tables. Restructures station sequences.
Vertical Alignment Formatter
Format profile exports, validate grades, remove blank lines, and check vertical curve consistency.
Superelevation Calculator
Fix broken superelevation parameters. Recalculate transition runoff stations for direct re-import to Civil 3D.
Survey CSV Cleaner (PENZD)
Clean, validate, and merge multiple survey exports. Auto-detects columns and maps description codes.
Excel Quantity Takeoff & QC
Compile volume reports, calculate project statistical summaries, and highlight variation indices.
BoQ Tool
Generate a hierarchical Bill of Quantities (BoQ) mapping design quantities to ERA 2013 or AACRA standard technical specifications.
Mass Haul Diagram Plotter
Plot standard mass haul curves, identify balance points, and optimize haul distances.
Culvert & Ditch Hydraulic Sizer
Calculate peak runoff Q=C·I·A/360 and size pipe/box culverts and trapezoidal roadside ditches per ERA Drainage Manual.
Stopping & Passing Sight Distance Calc
Determine required SSD, PSD, vertical curve K-values (Crest/Sag), and horizontal curve setback clearances (m_s) per ERA 2013.
Expansive Soil & Stabilization Sizer
Classify AASHTO soil groups (A-1 to A-7-6), evaluate Black Cotton Soil swelling threat, and calculate undercut, capping, and lime/cement stabilization.
Pavement Material Substitution Calc
Calculate structural layer equivalencies (SN), solve required layer substitution thicknesses (D_sub), and evaluate cost impact per ERA Pavement Manual 2013.
Roadside Guardrail & Safety Barrier Evaluator
Evaluate embankment fill/slope warrants, calculate Clear Zone recovery distance (L_CZ), select W-Beam/Thrie-Beam/New Jersey barriers, and compute Length of Need (L_N) per ERA Chapter 10.
ERA & AASHTO Rigid Concrete Pavement & Joint Calculator
Calculate JPCP and CRCP slab thickness, effective subgrade reaction (k_eff), transverse dowels & longitudinal tie-bars per ERA Pavement Design Manual Vol II 2013 & AASHTO.
Junction & Roundabout Geometry Checker
Evaluate roundabout ICD, entry radius, circulatory width, truck apron sizing, design vehicle swept paths (DV1-DV4/WB-15), and sight triangles per ERA Chapter 9.
Road Signs & Markings Quantity Estimator
Calculate thermoplastic paint area (m²), paint/glass bead weights (kg), retroreflective traffic signs schedule, cat-eye studs, and delineators per ERA Chapter 11.
Civil 3D LandXML Design Data & Centerline Formatter
Import Civil 3D LandXML alignments, extract centerline 1km matrices (CL), horizontal curves (HA), and vertical profile schedules (VA) with station equation correction.
ERA Flexible Pavement Design & Overlay Calc
Calculate flexible pavement layer structures (T1-T8/S1-S6), ESAL traffic growth, and structural overlay thicknesses strictly adhering to ERA 2013 manuals.
Structure Plan & Profile Generator
Generate plan and profile drawings for crossing structures using horizontal coordinate listings, profile PVI tables, and hydrology schedules.
ERA Terrain Classification & Longitudinal Grade Analyzer
Upload survey/alignment data in Excel or CSV to calculate longitudinal grades and classify terrain (Flat, Rolling, Mountainous, Escarpment) per ERA Geometric Design Manual 2013.
