CAD 2D Importer is the ultimate workflow accelerator for ArchViz, Engineering, and Simulation projects. Stop wasting time manually tracing spline references or dealing with messy "Datasmith" imports for simple 2D plans.
This plugin reads standard DXF (AutoCAD) files and our custom JSON schema (3ds Max Exporter included!) and converts them into Unreal Engine Spline Actors, organized neatly by Layer.
Key Features:
DXF Support: Imports Lines, Polylines, Circles, Arcs, and Splines (NURBS).
Layer System: Preserves CAD layers, allowing you to select, hide, or colorize groups of splines instantly.
Smart Unit Conversion: Automatically detects unit setup (mm, cm, m, in, ft) or allows manual override.
3ds Max Integration: Includes a Python script (`export_cad_json.py`) to export shapes from 3ds Max with 1:1 fidelity.
3D Building Tools:
Generate Walls: Extrude selected splines into 3D walls with adjustable height and thickness.
Weld Seams: Automatically merge disconnected vertices with a configurable threshold.
Mesh Operations: Clean normals, generate tangents, and collision.
Workflow
1. Import: Select your `.dxf` or `.json` file.
2. Review: See a preview of layers, toggle visibility, and set colors.
3. Spawn: Click to generate Spline Actors in your level.
4. Build: Use the built-in "3D Toolbox" to extrude walls or floors from your splines.
