CADSECTION

For railway, road and canal survey work

Cross sections, L‑sections and quantities, straight from the level book.

CADSECTION reads your level books, Excel sheets and .ESP project files, applies your templates and prints the sheets your office submits. Use it inside AutoCAD, or on its own as CADSECTION Studio – no AutoCAD needed.

Works with the files and instruments you already use

  • .ESP project files
  • Excel level books
  • Total-station and GPS points
  • Photos of handwritten level books
  • LandXML 1.2
  • AutoCAD 2025 or newer

How it works

From field data to the bill of quantities

The work in the order it is done – each step uses what the last one made, and every figure stays traceable.
  1. 01

    Field data

    Open .ESP project files and Excel level books as they are, put total-station or GPS points on the alignment, or let the AI read a photo of a handwritten level book row by row.

  2. 02

    Check

    Check Data lists what needs a second look: a section with one reading, swapped offsets, a level that jumps, a chainage out of order – each with a link to the section.

  3. 03

    Design

    Templates and multi-layer assemblies for roads, railway formations and canals; formation from levels or a vertical alignment; superelevation, cant and widening.

  4. 04

    Drawings

    Cross sections on sheets with your title block and band rows, the L-section with the plan above it. PDF, DXF, DWG or the printer; Hindi and Bengali print correctly.

  5. 05

    Quantities

    Areas and volumes by the trapezoidal or Simpson's rule, corrected on curves; mass haul, setting-out reports and a BOQ in Excel with live formulas.

Features

Everything a cross-section job needs

Every plan has all of it; the plans differ only in the AutoCAD plug-in and the AI.
All features

Templates and assemblies

Carriageway, shoulders, side slopes to the ground, berms, drains, multi-layer crusts and railway formations, applied by chainage range.

Curves

Superelevation e = V²/225R and IRC extra widening for roads; equilibrium cant and formation widening for railways, run in along the transitions.

Widening and strengthening

Overlay with profile correction, milling where the old road is high, full crust on the widening with box cutting – volumes and BOQ items.

Canal design

Bed width, depth, velocity and free board per reach by Manning's formula or Lacey's regime theory (IS 10430 / IS 7112), then the lining quantity.

Print Center

Check every sheet before printing; PDF (one per sheet or all in one), DXF, DWG or the printer, with an index of the drawings as the first sheet.

Quantities and mass haul

Several area combinations at once, shrinkage on filling, free haul and overhaul, turfing and benching, an abstract of quantities.

Survey and surfaces

Survey points and TIN surfaces, contours with labels, spot levels, cut and fill maps, sections cut from a surface at any interval.

Exchange

LandXML in and out for Civil 3D, OpenRoads and 12d; DXF checked in AutoCAD; settings files to share your band rows and title block.

AI Copilot

Tell it what to change, in plain words

It answers with a list of steps; nothing changes until you press Apply, and one Undo takes it all back. It can also read a level book from a photo, find doubtful sections and summarise quantities as a table.

You type

“Fit every section to 12.5 m and use Simpson's rule.”

Set the width of every section to 12.5 m

Change the volume method to Simpson's rule

Recompute the areas and volumes

The Copilot uses AI credits. Pro and Pro Max include credits every year; credit packs can be added to any plan.

AI apps · Pro Max

The AI apps you already use can work in CADSECTION

Claude Desktop, ChatGPT, Cursor and other apps that support MCP look up readings, areas and volumes, change sections and templates, import level books and write reports – with your own subscription to the app, no CADSECTION credits used.

  • Claude Desktop
  • ChatGPT
  • Cursor
  • VS Code + GitHub Copilot
  • Codex
  • Gemini CLI
  • LM Studio
  • Windsurf

The app asks you before it changes anything; each app's changes are one step of Undo. Included in Pro Max and Govt / Railways licences, and in a firm's Pro seat with the own-AI-key add-on.

How AI apps work

Two ways to run it

On its own, or inside AutoCAD

Both open the same project files, so a team can mix them.

CADSECTION Studio

A normal Windows program with a ribbon like AutoCAD's – no AutoCAD licence needed. Every plan includes it.

Windows 10 or 11 · 64-bit and 32-bit editions

The AutoCAD plug-in

Adds the same tools to AutoCAD and draws straight into your drawing. Included in Pro and Pro Max, and in the trial.

AutoCAD 2025 or newer

Questions

Good to know before you start

Something else? Write to us or look in the help centre.
Can I use my existing .ESP project files?
Yes. .ESP project files (the file format of ESurvey CADD) open directly with your sections, layers, templates, formation and project details, so you can keep working on your own data; Excel level books (Series, Layers and level-book sheets) are imported with a preview first. CADSECTION is an independent product: it reads these files for compatibility only and is not affiliated with or endorsed by the maker of ESurvey CADD.
Do I need AutoCAD?
No. CADSECTION Studio is a program of its own and every plan includes it. If you work in AutoCAD, the plug-in (Pro and Pro Max) adds the same tools to AutoCAD 2025 or newer.
What does the free trial include?
14 days with every feature, including the AutoCAD plug-in, without a card. Drawings and PDFs made in the trial carry a TRIAL mark. If you buy during the trial, it becomes the paid licence on the same PC.
What does Lifetime mean?
Lifetime is for the Standard plan: you pay once and it runs for 15 years from the day you buy, with the updates and support of Standard for those years.
Can I move my licence to a new PC?
Yes – from My account or from CADSECTION: twice a year on Standard and Pro, four times on Pro Max. For more moves, write to us.
Does my survey data go to your server?
No. Your projects stay on your PC. Only what you send to the AI Copilot leaves it, to answer your request.

Try it on your own level book

14 days with every feature, no card needed. Drawings made in the trial carry a TRIAL mark; AI credits can be bought separately.
