How Gitails Converts CAD Drawings to Native Parametric BIM

From 2D orthographic line work to non-bloated, fully parameterized Autodesk Revit (.rfa) families in under 60 seconds.

How Gitails works

Core compiler onlinev2.14.0-revit

STEP 01upload_file

Upload your drawings

We can process PDF, DWG, and DXF files!

STEP 02tune

Check and edit your parameters

Parameters are constraints and editables for your product's flexibility as a family inside revit!

STEP 03download_done

Done! Download your new Revit parametric family.

Your products are ready to use in Revit!

Supported Drawing Formats & Ingestion Rules

Gitails operates strictly on true mathematical coordinates. Raster files and polygon meshes fail pre-flight validation automatically.

CAD Drawing Format	Compatibility	Geometry Pipeline	Specifications / Constraints
picture_as_pdfPDF (Vector-stored)	✓ Supported	Vector Extraction	Direct vector path extraction from AutoCAD / Rhino / Illustrator. Text and witness lines preserved.
architectureDWG (AutoCAD Drawing)	✓ Supported	Binary DWG Ingestion	Native AutoCAD R14–2026 DWG. Polyline geometry, layers, and blocks parsed.
schemaDXF (Exchange Format)	✓ Supported	ASCII / Binary Parser	ASCII/Binary DXF standard format. Clean 2D linework and dimension entities extracted.
document_scannerScanned PDF (Raster / Bitmap)	✗ Unsupported	Pixel Sheet (Rejected)	Scanned paper drawings or rasterized pixel sheets. Lacks explicit coordinate vertex data.
imagePNG / JPG (Raster Images)	✗ Unsupported	Bitmap Array	Pixel bitmaps cannot reliably generate parametric CAD constraints or dimension witness lines.
deployed_code3D Mesh (OBJ / FBX / 3DS)	✗ Unsupported (Bloat Warning)	Tessellated Mesh	Polygon meshes create bloated, unusable Revit families. Gitails strictly generates clean Revit solid extrusions and sweeps.

Parametric Reference Planes

The engine maps 2D orthographic dimensions directly to centered, pinned reference planes with mathematical equality constraints (`EQ`) and dimension parameters.

Solid CSG Extrusions Only

Zero facet surfaces or imported DWG blocks inside families. All shapes are native Revit solid extrusions, sweeps, and revolves capable of section-cutting cleanly.

dataset

Standard Parameter Dictionaries

Extracts schedule data directly: OmniClass™, MasterFormat™, IFC classification, model numbers, and material parameters pre-populated into the family definition.
