Why we like it

DXF Import Export stands out in the superhive library for its focus on practical DXF work — reference-point placement, layer-based structure, and real-world coordinates — rather than covering every corner of the DXF specification.

What is Dxf Import Export - Geodetic & Construction Workflow?

DXF Import Export – Geodetic & Construction Workflow is a Blender add-on for bringing DXF drawings into real-world coordinates and exporting geometry back out. It targets geodetic, construction, and technical workflows where DXF files serve as reference geometry, underlays, or a base for further modeling.

On import, it reads commonly used DXF entities from model space and splits the content into Blender collections by DXF layer. Line color and thickness carry over from layer settings, and an optional Geometry Nodes setup gives visible line thickness. Reference-point import and export place drawings in real-world coordinates, with axis orientation and rotation support for matching external coordinate systems.

For export, the add-on writes LWPOLYLINE from mesh edge chains, 3DFACE from triangulated mesh faces, and TEXT and MTEXT from Blender Font objects. It is intended for practical DXF work rather than full lossless DXF roundtripping, and runs on Blender 5.0 and later.

Who is Dxf Import Export - Geodetic & Construction Workflow best for?

Dxf Import Export - Geodetic & Construction Workflow is best for geodetic, construction, and technical workflows that use DXF drawings as reference data, underlays, or base geometry in real-world coordinates.

How much does Dxf Import Export - Geodetic & Construction Workflow cost?

Dxf Import Export - Geodetic & Construction Workflow is completely free to download and use.

Frequently asked questions

Does DXF Import Export work with Blender 5.0?

DXF Import Export requires Blender 5.0 or later and is listed as compatible with the Blender extensions system. It works with the standard render engines, Cycles and Eevee. The add-on is built for practical DXF workflows, so it focuses on reliably importing and exporting usable geometry rather than supporting full lossless DXF roundtripping. If you work in an earlier Blender release, check the developer's page before installing to confirm the version you need for your setup.

What DXF entities can DXF Import Export import?

DXF Import Export reads commonly used DXF entities from model space, including LINE, ARC, CIRCLE, POLYLINE, LWPOLYLINE, SPLINE, ELLIPSE, POINT, 3DFACE, SOLID, TRACE, MESH, DIMENSION, TEXT, and MTEXT. As it imports, it splits the content into Blender collections organized by DXF layer, and it transfers line color and thickness from the layer settings. An optional Geometry Nodes setup provides visible line thickness for the imported lines, which helps when using the drawings as underlays or references.

Can DXF Import Export export geometry back to DXF?

DXF Import Export handles export as well as import. It writes LWPOLYLINE from mesh edge chains, 3DFACE from triangulated mesh faces, and TEXT and MTEXT from Blender Font objects. Reference-point export places the output in real-world coordinates, with axis orientation and rotation support for matching external coordinate systems. This makes it suitable for producing DXF underlays and simplified practical DXF data for downstream technical workflows, though it is not aimed at full lossless DXF roundtripping.

Is DXF Import Export free to use?

DXF Import Export is listed as free here and distributed under the GPL license. Licensing terms can change over time, so check the developer's page for the current details before you download. Beyond licensing, the add-on is aimed at geodetic, construction, and technical DXF workflows in Blender, where reference-point placement, layer-based structure, and real-world coordinates matter for using drawings as references or underlays.
