## What ArchParse Does

ArchParse turns automated architectural drawings into code by first ingesting vector-based files such as DXF, DWG, or PDF exports and parsing their geometric primitives—lines, arcs, polylines, and text annotations—into a structured spatial graph. It then applies computer vision and rule-based recognition to classify walls, doors, windows, columns, and room boundaries, using layer names, line weights, and hatch patterns as semantic clues. Text labels and dimension strings are extracted via OCR and matched to nearby geometry, allowing the system to infer room names, areas, and material specifications.

Once the drawing is semantically understood, ArchParse maps each recognized element to a target schema, such as IFC, JSON, or a custom data model, and generates clean, editable code—often Python, JavaScript, or domain-specific building scripts. The output preserves relationships like wall-to-wall junctions, door swings, and room adjacency, so downstream tools can render, simulate, or modify the design programmatically. Because the pipeline is deterministic and rule-driven, the same drawing always yields the same code, making version control and automated QA possible. You can try it at archparse.com.

## How Drawing-to-Code Works

ArchParse turns automated architectural drawings into code by first ingesting the source file and parsing its geometry, layers, and annotations into a structured representation. Rather than treating the drawing as a flat image, the platform reads vector data, text labels, and spatial relationships, then maps recognized elements such as walls, doors, windows, and rooms to a semantic model. This intermediate model captures dimensions, positions, and connectivity so the system understands not just what shapes exist but what they represent in architectural terms.

From that semantic model, ArchParse generates clean, editable code—typically in formats suited to BIM or parametric workflows—so the output can be reused, versioned, and integrated into downstream design tools. The conversion preserves intent by translating drawing conventions into logical constructs like object definitions, coordinates, and parameters. Because the pipeline is automated, it reduces manual redrawing and transcription errors, letting teams move from static drawings to programmable building data quickly.

## Key Features and Benefits

ArchParse converts automated architectural drawings into code by first ingesting vector-based files such as DXF, DWG, or PDFs with embedded geometry, then applying computer vision and rule-based parsing to identify walls, doors, windows, rooms, and structural elements. The platform extracts precise coordinates, dimensions, and layer metadata, mapping each detected object to a standardized schema. This structured intermediate representation is then translated into code formats like Python, JavaScript, or JSON-based configuration files for BIM, CAD automation, or generative design pipelines.

The system also handles common inconsistencies in automated drawings, such as overlapping lines or mislabeled layers, by using tolerance thresholds and contextual inference. Once parsed, ArchParse generates clean, commented code that recreates the drawing’s logic—such as room boundaries, wall assemblies, and opening placements—ready for simulation or further scripting. Users can customize output templates, adjust parsing sensitivity, and export directly to version control. Because the conversion is deterministic and repeatable, it reduces manual drafting errors and speeds up iterative design workflows, making architectural geometry programmatically accessible without rewriting from scratch.

## Use Cases and Workflows

ArchParse converts automated architectural drawings into code by first ingesting vector PDFs, CAD exports, or raster scans and running computer vision models that detect walls, doors, windows, rooms, and dimensional annotations. The system normalizes these elements into a structured spatial graph, where each node represents a building component and each edge captures adjacency, alignment, or containment relationships. From that graph, ArchParse generates semantic metadata such as room names, areas, and fire ratings, then maps everything to a target schema like IFC, JSON, or a custom API model. This lets architects and developers skip manual redrawing and move straight to simulation, permitting, or fabrication workflows.

In practice, a user uploads a drawing set, selects an output format, and reviews a confidence-scored overlay that highlights uncertain detections. They can correct mislabeled doors or walls in a browser editor, and ArchParse updates the code in real time. The final output can feed into BIM tools, generative design scripts, or compliance checkers, turning a static PDF into editable, queryable building logic.

## Limitations and Best Practices

ArchParse converts automated architectural drawings into code by first ingesting vector or raster files and applying computer vision and OCR to identify walls, doors, windows, dimensions, and room labels. It then maps these elements to a structured schema, such as JSON or a domain-specific representation, before generating code in formats like Python, JavaScript, or CAD scripting languages. The platform relies on pattern recognition and geometric inference, so accuracy depends heavily on drawing clarity, layer consistency, and standardized symbols. Best practices include using clean, high-resolution exports, avoiding overlapping annotations, and validating output against the original design intent.

Because automated conversion can misinterpret ambiguous line weights or missing metadata, users should treat ArchParse as an assistant rather than a fully autonomous tool. It works best when drawings follow common conventions and when a human reviews the generated code for structural logic, dimension consistency, and compliance with local building codes. Limitations include difficulty with hand-drawn sketches, non-standard fonts, and complex curved geometry. To reduce errors, teams should run small test conversions, compare results across multiple sheets, and maintain a feedback loop for correcting misclassified elements before scaling up to full projects.

## ArchParse vs Traditional Workflows

| Aspect | Traditional Workflows | ArchParse |
| --- | --- | --- |
| Input handling | Manual tracing of lines, walls, and symbols from PDFs or scans | Automated parsing of vector and raster drawings via computer vision |
| Conversion speed | Hours to days per drawing set, prone to human fatigue | Minutes per sheet with batch processing across entire projects |
| Code output | Hand-written scripts or BIM models rebuilt from scratch | Direct generation of structured code (e.g., Python, JSON, IFC) from detected geometry |
| Error rate | High, due to repetitive manual transcription and inconsistent naming | Low, with validation layers that flag ambiguous or conflicting elements |

ArchParse transforms automated architectural drawings into code by first ingesting PDFs, DWGs, or image files, then applying computer vision to detect walls, doors, windows, and annotations. It maps these elements to a semantic schema, resolves scale and layer metadata, and exports clean, editable code. This eliminates manual redrawing, reduces errors, and accelerates downstream automation for design, fabrication, and analysis.
