2D CAD → 3D BIM Auto-Modeling
Parses 2D CAD (.dxf) into object-level semantics and auto-converts to Revit / IFC — across architectural floor plans and RC structural drawings.

Context
Developed with general-contractor BIM teams and structural design teams handling large volumes of legacy 2D CAD documentation that must be converted into BIM-ready models for coordination and delivery.
The bottleneck
Converting 2D CAD drawings to 3D BIM models was manual and labor-intensive. Teams needed to parse .dxf files, interpret object types, and reconstruct 3D Revit geometry — combining geometric interpretation with BIM domain knowledge, with no adequate automation. Architectural floor plans and RC structural drawings each carry distinct object semantics (walls and openings vs. column grids, beam layouts, and slab extents).
What we built
A pipeline that parses .dxf files, applies semantic object recognition to identify walls, columns, slabs, beams, and openings, then auto-generates corresponding Revit families and assembles an IFC-compliant 3D model. Covers both standard architectural floor plans and RC structural framing layouts.
Engagement
Outcome
Active track. Working builds handle standard floor-plan and RC framing typologies. Formal build expanding to additional member types and MEP rough-in.
