CAD Bridge is the missing link between your CAD software and Unreal Engine. Drop a DXF file into the Content Browser and get editable spline actors and reusable assets with colors, layers, and hierarchy intact. Re-import the same file after design changes to update your scene in place, and export modified splines back to DXF for round-trip workflows.

Supported DXF Entities

LINE, ARC, CIRCLE, LWPOLYLINE, POLYLINE, SPLINE, and POINT

Import Features

• Layer-based filtering with checkbox UI, colour swatches, entity counts, and a search box — import only the layers you need

• Per-layer colour overrides — click a layer's swatch to pick a custom import colour

• Combine per layer — merge all curves and/or points on a layer into a single actor/asset, so large files don't create thousands of objects

• Reimport / update (Experimental) — import the same file again and existing actors update in place: no duplicates, deleted entities are cleaned up

• Three import modes: Actors Only, Assets Only, or Both (Blueprint assets + level actors)

• DXF color retention — ACI palette, 24-bit RGB, and BYLAYER inheritance

• Automatic unit scaling from DXF $INSUNITS (inches, mm, metres)

• Import from local drives or network shares

• Organized Outliner hierarchy grouped by DXF layer and sublayer (e.g. from Rhino)

Export Features

• Export selected spline actors back to DXF format

• Point actors exported as DXF POINT entities

• Automatic coordinate system conversion (UE left-handed to DXF right-handed)

Built-in Spline Tools

• Explode: split multi-segment splines into individual actors

• Join: merge connected splines back into continuous curves

• Center Pivot: reposition actor origin to spline bounding box center

Randomization Tools

• Sub-select by percentage

• Random scale, rotation, and offset within configurable ranges

Designed for architectural visualization and animation workflows.
