Specifically, the keyword "Progiscad 2002 2004 adcof adfer adtopo hot" refers to a pivotal era in the software's history, focusing on a suite of modules—ADCOF, ADFER, and ADTOPO—that have evolved from early 2000s AutoCAD-based plugins into modern ADCAD BIM solutions . The Core Modules of Progiscad

• Rail track alignment design (circular curves, clothoids, straight sections).
• Cant (superelevation) calculation and visualization.
• Clearance gauge analysis (tunnels, platforms, overhead lines).

These two versions represent the "golden era" of the software. Many French cabinet de géomètres (surveying firms) and DDE (Direction Départementale de l'Équipement) offices standardized on these releases. By 2006, ProgisCad was largely replaced or merged into other platforms, but the 2002–2004 data formats persisted for over a decade.

Step 1: Recover the Data Without ProgisCad

• ProgisCAD saved native drawings as .dwg (AutoCAD 2000/2004 format) + project files (.prg extension for ADCOF/ADFER data).
• To open today:

  Running or migrating old .prg / .dwg files
