VectorForge CAD

Engineering Precision. Modern Simplicity.

Professional PDF Vector → DXF Conversion Platform

Convert vector PDF drawings exported from AutoCAD®, Civil 3D®, Revit®, Inventor® and SolidWorks® into editable DXF files with enterprise-grade precision.

---

---

Overview

VectorForge CAD is an enterprise-grade web application that converts vector PDF engineering drawings into editable DXF files while preserving geometry, structure and CAD compatibility.

Unlike conventional PDF converters that rely on rasterization, VectorForge CAD extracts vector entities directly from mathematical paths, reconstructing CAD geometry with high precision.

The platform is intended for engineering companies, architects, surveyors, electrical designers, mechanical designers and CAD professionals.

Removes duplicated and reversed segments.

Polyline reconstruction

Connects continuous segments into optimized LWPOLYLINE entities.

Floating point correction

Automatically snaps nearby vertices using configurable tolerances.

Collinear simplification

Eliminates unnecessary intermediate vertices.

Geometry validation

Repairs invalid entities before DXF export.
