DXF-importer will help you to import
DWG
and DXF
files to Blender-3D.
I have been developing and maintaining the importer since 2007.
It is a part of official distribution since Blender 2.45.
Since Blender 2.50 the importer got a replacement because of the new python-API.
DXF-importer PE (Personal Edition) is an enhanced version of the importer,
developed in the context of CADtools Project. The motivation was to overcome
a number of limitations Blender has by importing big lists of objects.
The new engine supports DXF and DWG files of any largeness and complexity at constant transfer rate.
There are dedicated versions for Blender 2.49b, 2.7/8/9 and 3/4.x. All these versions are actively maintained and continuously developed.
Features:

llll.....l.....l.. - color
lllllll..llll..lll - layer
DXF-r12 objects:
llllllllllllllllll - POINT
llllllllllllllllll - LINE
llllllllllllllllll - CIRCLE
llllllllllllllllll - ARC
llllllllllllllllll - TEXT
llllllllllllllllll - 3DFACE
llllllllllllllllll - 2d-POLYLINE (incl. arc, variable-width, curve, spline)
llllllllllllllllll - 3d-POLYLINE
llllllllllllllllll - 3d-POLYMESH
llllllllllllllllll - 3d-POLYFACE
llllllllllllllllll - SOLID
llllllllllllllllll - TRACE
llllllllllllllllll - INSERT and BLOCK

llll.....l.....l.. - XREF (External Reference)
llllll...l.....l.. - VIEW
llllll...l.....l.. - VIEWPORT
...l.....l.....l.. - DIMENSION
...l..l..l.....l.. - MLINE
...llll..llll..lll - MTEXT
...l.....l.....l.. - HATCH
DXF>r12 objects:
llllllllllllllllll - ELLIPSE
llllllllllllllllll - LWPOLYLINE (LightWeight Polyline)
llllll...lll...lll - SPLINE
...lll...lll...lll - REGION (ACIS/SAT) (via external converter)
...lll...lll...lll - 3DSOLID (ACIS/SAT) (via external converter)
Notes: - All BLOCKs are imported to layer 19, then referenced as DupliGroup/Collection for each INSERT point.
Big number of BLOCKs (over 700) may decrease import and editing performance.
- DXF-properties can be used to assign Blender materials.
- Native support for ACIS objects (REGION, 3DSOLID) is still under construction.
For now ACIS objects can be imported into Blender only via conversion to mesh objects.
There are three methods available:
>> convert 3DSOLIDs to POLYFACEs via "explode" inside AutoCAD before export to DXF format.
>> OR export to DXF r12 format - 3DSOLIDs will be converted on-the-fly to POLYFACEs.
>> OR set up external converter and use "DXF-r12" import parameter (this will force the conversion).
- You may need to run 'RemoveDoubles' on imported meshes.
- You can import into Blender 2.49, then read the blend file in Blender 2.6+. It works in both directions.
Manual: on Blender 2.65/2.7x/2.8x/2.9x/3.x/4.x:
- Getting Started.
on Blender 2.49b:
- the documentation on blender-wiki.
Support: For individual support you can contact me per email: "DXF-support ...".
The importer can read DXF data of any complexity - even broken / corrupted files
can be handled properly.
Configuration panel offers big number of options allowing precise control over import process.
You should invest some time to learn how to use it effecively.
With help of proper configuration you can minimize import time and significantly reduce pre- and post-processing efforts.
