DGN to Excel Conversion

Business Case

Problem Statement

DGN files are common in infrastructure and civil engineering:

Transportation and highway design
Bridge and tunnel projects
Utility networks
Rail infrastructure

Extracting structured data from DGN files for analysis and reporting can be challenging.

Solution

Convert DGN files to structured Excel databases, supporting both v7 and v8 formats.

Business Value

Infrastructure support - Civil engineering focused
Legacy format support - V7 and V8 DGN files
Data extraction - Levels, cells, text, geometry
Batch processing - Process multiple files
Structured output - Excel format for analysis

Technical Implementation

CLI Syntax

DgnExporter.exe <input_dgn>

Supported Versions

Version	Description
V7 DGN	Legacy MicroStation format (pre-V8)
V8 DGN	Modern MicroStation format
V8i DGN	MicroStation V8i format

Output Format

Output	Description
`.xlsx`	Excel database with all elements

Examples

# Basic conversion
DgnExporter.exe "C:\Projects\Bridge.dgn"

# Batch processing
for /R "C:\Infrastructure" %f in (*.dgn) do DgnExporter.exe "%f"

# PowerShell batch
Get-ChildItem "C:\Projects\*.dgn" -Recurse | ForEach-Object {
    & "C:\DDC\DgnExporter.exe" $_.FullName
}
