-This is a Blender import script for dxf files.
+This script imports DXF objects (2d/3d) into Blender.
-This script imports the dxf Geometery from dxf versions 2007 and earlier.
+This script imports 2d and 3d Geometery from DXFr12 format files.
+This version is focused on import of 3d-objects.
-Supported:<br>
- At this time only mesh based imports are supported.<br>
- Future support for all curve import is planned.<br>
- <br>
-Currently Supported DXF Ojects:<br>
- Lines<br>
- LightWeight polylines<br>
- True polylines<br>
- Text<br>
- Mtext<br>
- Circles<br>
- Arcs<br>
- Ellipses<br>
- Blocks<br>
- 3Dfaces<br>
+Supported DXF Objects:
+LINE
+POINT
+SOLID
+TRACE
+TEXT
+INSERT (=block)
+MINSERT (=array)
+CIRCLE
+ARC
+3DFACE
+2d-POLYLINE (=plane, incl. arc, variable-width, curve, spline)
+3d-POLYLINE (=no-plane)
+3d-POLYMESH
+3d-POLYFACE
+under construction, partly supported DXF>r12:
+LWPOLYLINE (LightWeight), MLINE, MTEXT, ELLIPSE
-Known issues:<br>
- Does not convert perfectly between Object Coordinate System (OCS)
- and World Coordinate System (WCS). Only rudimentary support for
- true polylines have been implimented - splines/fitted curves/
- 3d plines/polymeshes are not supported.
- No support for most 3d entities. Doesn't support the new style object
- visability. There are problems importing some curves/arcs/circles.
+Unsupported DXF Objects:
+DXF r12: DIMENSION, XREF (External Reference)
+DXF>r12: SPLINE, GROUP, RAY/XLINE, LEADER, 3DSOLID, BODY, REGION, dynamic BLOCK
-Notes:<br>
- This is primarally a 2d drawing release. Currently only support for
- 3d faces has been added.
- Blocks are created on layer 19 then referenced at each insert point. The
- insert point is designated with a small 3d crosshair. This handle does not render.
+Supported Properties:
+Hierarchy: Entire DXF BLOCKs hierarchy is preserved after import into Blender
+visibility, frozen
+COLOR
+LAYER
+thickness
+width
+(todo: grouped, XDATA)
+It is recommended to use DXF-object properties for coding Blender materials.
+Notes:
+- Recommend that you run 'RemoveDoubles' on each imported mesh after using this script
+- Blocks are created on layer 19 then referenced at each insert point.
+* Big DXF-files (over 1500 objects) decrease import performance. The problem is not the inefficiency of python-scripting but Blenders performance in creating new objects in his database - probably a database management problem.
+* The Blender curves of imported ARCs and POLYLINE-arc-segments have light malformed ends.(to fix in beta10)
+- Bug in newScene-option: ARCs and CIRCLEs are drawn at (0,0,0). (wip)
+
+TODO:
+- filtering of unused/not-inserted Blocks
+- the new style object visibility
+- support for Spline-curves, Besier-curves
+- support for real 3d-solids (ACIS)
+- (to see more, search for "-todo-" in script)
+
+
+History:
+ v1.0 08.2007 by migius: "full 3d"-release
+ TODO:
+ -- command-line-mode/batch-mode
+ -- human-formating of data in INI-File
+ -- suport for MLine
+ -- suport for Ellipse
+ -- suport for Mtext
+ -- blender_object.ID.properties[dxf_layer_name]
+ -- Configuration files(.ini) can handle various material setups
+ -- added f_layerFilter
+ -- to-check: new_scene-idea from ideasman42: each import create a new scene
+ -- to-check: obj/mat/group/_mapping-idea from ideasman42:
+ -- better support for long dxf-layer-names
+ -- support width_force for LINEs/ARCs/CIRCLEs/ELLIPSEs = "solidify"
+ -- added fill/non-fill option for closed curves: CIRCLEs,PLINEs
+ -- bug:? Circle/Arcs in each "newScene" drawn at <0,0,0>
+ -- bug:? object = Object.Get(obname) -> = SCENE.getChildren(obname)
+ beta09: 02.09.2007 by migius

+ d2 redesign: progressbar
+ e- tuning by ideasman42: better use of the Py API.
+ c- tuning by ideasman42
+ b- rewrite f_Text.Draw rotation/transform
+ b- bugfix: POLYLINE-segment-intersection more reliable now
