Release note by migius (DXF support maintainer) 2011.01.02:
Script supports only a small part of DXF specification:
- imports LINE, ARC, CIRCLE, ELLIPSE, SOLID, TRACE, POLYLINE, LWPOLYLINE
- imports TEXT, MTEXT
- supports 3d-rotation of entities (210 group)
- supports THICKNESS for SOLID, TRACE, LINE, ARC, CIRCLE, ELLIPSE
- ignores WIDTH, THICKNESS, BULGE in POLYLINE/LWPOLYLINE
- ignores face-data in POLYFACE / POLYMESH
- ignores TEXT 2d-rotation
- ignores hierarchies (BLOCK, INSERT, GROUP)
- ignores LAYER
- ignores COLOR, LINEWIDTH, LINESTYLE
This script is a temporary solution.
Probably no more improvements will be done to this script.
The full-feature importer script from 2.49 will be back in 2.6 release.
Installation:
Place this file to Blender addons directory
(on Windows it is %Blender_directory%\2.53\scripts\addons\)
You must activate the script in the "Add-Ons" tab (user preferences).
Access it from File > Import menu.
