DXF Import Export – Geodetic & Construction Workflow

DXF Import Export is a practical Blender add-on for working with DXF drawings in real-world coordinates.

It is designed for geodetic, construction, and technical workflows where DXF files need to be imported as usable reference geometry, organized by layers, and exported back from Blender in a form that is useful in practice.

Instead of trying to support every corner of the DXF specification, this add-on focuses on what matters most in real production work:
reliable placement by reference point, layer-based organization, readable line styling, and practical geometry export for downstream use.

What This Add-on Does

• Imports commonly used DXF entities from model space

• Splits imported content by DXF layer into Blender collections

• Supports reference-point transformation for world-coordinate workflows

• Transfers line color and thickness from DXF layer settings

• Exports practical DXF geometry from Blender meshes and text objects

• Helps use DXF drawings as underlays, references, or a base for further modeling

Key Features

Import

• Reads commonly used DXF entities from model space:
  LINE, ARC, CIRCLE, POLYLINE, LWPOLYLINE, SPLINE, ELLIPSE, POINT, 3DFACE, SOLID, TRACE, MESH, DIMENSION, TEXT, MTEXT

• Splits imported entities into Blender collections by DXF layer

• Supports line color and thickness from layer settings

• Optional Geometry Nodes setup for visible line thickness

World Coordinates

• Reference-point import and export

• Placement in real-world coordinates

• Axis orientation support

• Rotation support for matching external coordinate systems

Export

• Exports LWPOLYLINE from mesh edge chains

• Exports 3DFACE from triangulated mesh faces

• Exports TEXT and MTEXT from Blender Font objects

• Useful for DXF underlays and downstream technical workflows

Typical Use Cases

• Importing DXF drawings as reference data in Blender

• Using technical underlays in world coordinates

• Preparing base geometry for geodetic and construction models

• Creating DXF underlays for Machine Control workflows

• Exporting simplified practical DXF data from Blender

Requirements

• Blender 5.0+

• Intended for practical DXF workflows, not full lossless DXF roundtripping

Why Use DXF Import Export?

Because in technical workflows, DXF data must be usable, organized, and correctly placed in coordinates that match reality.

This add-on is built for practical DXF work in Blender where reference-point placement, layer-based structure, and real-world workflow matter more than theoretical support for every DXF feature.
