DXF-Library log:
v1.31 - 2009.06.02 by migius
- modif _Entity class: added paperspace,elevation
v1.30 - 2009.05.28 by migius
- bugfix 3dPOLYLINE/POLYFACE: VERTEX needs x,y,z coordinates, index starts with 1 not 0
DXF-Importer: minor changes
DXF-Exporter log:
v1.34 - 2009.06.02 by migius
- support XYmirrored 2d-curves to POLYLINEs: works correct only for rotX,rotY==0.0
- support thickness and elevation for curve-objects
- fix extrusion 210-code (3d orientation vector)
- fix POLYFACE export, synchronized with dxfLibrary.py
- changed to the new 2.49 method Vector.cross()
- output style manager (first try)
v1.33 - 2009.05.25 by migius
- bugfix flipping normals in mirrored mesh-objects
- added UI-Button for future Shadow Generator
- support curve objects in projection-2d mode
- UI stuff: camera selector/manager
- script template use new property syntax
- Python could set the axis/hat to a negative index and crash blender (nobody complained)
- Servo control UI had overlapping text
- CValue warning ShowDeprecationWarning("val = ob.attr", "val = ob['attr']"); had false positives because of python using getattr() internally. Only show the wanring now when a CValue is found.
- Py functions that accepted a vector and a GameObject were slowed down by PySequence_Check() first called on the GameObject, though this would fail it would try and get attributes from the game object - ending up in ~8 attribute lookups each time. Avoiding PySequence_Check() makes ob.getDistanceTo(otherOb) over twice as fast.
- Joystick hat events could crash the BGE for joysticks with more then 4 hats.
- PLY Import failed on PLY files from Carve, added some extra types.
* object_drop.py - option to orient to face normal (useful for scattering objects over terrain), accounts for normal flipping and can adjust the orientation %.
- Fixed some deprecation warnings in documentation.
- Added more conversions to script.
- Added more attributes to script todo list.
- Print out name of text buffer when encountering an error in batch mode.
- Refactor: Simplified attribute map.
- Added notImplemented function to print warnings for missing conversions. References documentation.
Patch from Alex Fraser (z0r)
- All attributes in the conversion map have been checked against the docs. More ambiguities have been resolved.
- Added option to convert all text buffers in Blender.
- Updated GameTypes.py: there were inconsistencies.
The script works well (causes no errors) with 0_FPS_Template.blend and vehicle_demo.blend from the
physics-2.43-physics-testfiles pack.
Caveats:
- Conversions were checked against other deprecated attributes. I may have missed some cases where a deprecated attribute
has the same name as a non-deprecated attribute. I did catch a few though.
- As with the last version, the conversion is purely text-based and doesn't compile the code. It's easy to create a
script that would break on conversion.
Still, it should get you 90% of the way to a converted script.
V2.00 22/05/09 by Aaron Keith
- Better error checking.
- Lock Nut and Hex Nut meshes added.
- Pre-sets for common metric bolts and nuts.
- Improved GUI.
- Meshes scaled to a smaller size
- Fixed bug when using crest and root percent other than 10%
- Can now create meshes in Edit Mode. This will add to the
current mesh and align with the current view.
[#18765] Update of the rvk1_torvk2.py bundled script:
The script has been modified to use the last management of the modifiers in the python api and corrected too. Now it
can copy the mesh object when it is alone and also a shape keys to the second one if needed.
Patch from Roger Wickes update to 2.48 sFrame, eFrame, fps.
[#18794] GE API conversion script: 2.48 -> 2.49
patch from Alex Fraser (z0r), will test further in the next few days.
---
This is text plug in and standalone script that updates Blender 2.48 Game Engine scripts to be compatible with the 2.49
API.
The script contains a mapping of attribute names to functions that do the conversion. Most of the mappings were extracted
from the documentation in GameTypes.py. Where the conversion is ambiguous, the script will not change the source except
to insert a warning as a comment. This means that the script does not completely automate the conversion process, but
will do a lot of the work.
The script still needs a fair bit of testing. Many of the mappings have not been tested and could result in broken scripts.
I'm submitting this patch now to start the review process early. I think I might need help if it is to be included in
2.49.
in 2.48 constant interpolations meant that wasnt a problem but since it now uses linear interp. you can notice errors with animated characters because the 2 eulers are not compatible.
Added optional euler_compat argument to matrix.toEuler(eul) and quat.toEuler(eul) so when getting the euler rotations from a list of matrices the animation curve will be continues.
Also added euler.makeCompatible(euler).
- warning silenced for imagepaint.c
* FBX Bugfix, was exporting all animation curves as 'Constant' type (no docs for this so could only guess), Thanks to Sander Brandenburg for spotting this problem.
Also improved keyframe removal to work on animation curves an angle
from Paolo Ciccone (pciccone)
Im not that keen on this functionality since vertex groups in blender are for weight painting and OBJ's groups are more like sub-objects, The conversion between these is a poor approximation (one vertex group per face).
But this is still useful for using blender with poser so accepting these 2 patches.
Made some changes from the patch
*Export*
- vgroup off by default, since this is mainly useful for corner cases
- findVertexGroupName() - changed how exporting selects a vertex group for a face, use the highest combind weight for each group instead of the number of checking how many times the verts are in a group because they could have a zero weight.
- findVertexGroupName() - would fail if a faces verts were not in any groups, now return a (null) group
- Allow modifiers to export with vgroups
*Import*
- disable by default
- ignore (null) groups
- fixed a problem where the patch broke SPLIT_GROUPS
- move the group definition out of global namespace, breaks importing as a module.
--- Patch submission info
The import/export scripts included with Blender 2.48 don't save/preserve groups defined in OBJ file. This presents a
couple of issues: users loading an obj file with groups are not able to use a rather important set of data. When the
file is then saved the groups are lost bringing up both the issue of data loss and loss of functionality as groups are
used for rigging and morph target creation for Poser/DAZ Studio and all compatible applications. Of course other
animation/modeling packages that use OBJ files might be affected.
The solution that I present here simply patches the excellent python scripts written by Campbell Barton and Jiri Hnidek.
The new code implements the preservation of groups by creating Blender vertex groups during import and by re-writing
those groups in the OBJ file during export. Of course group ownership is idetermined at the face/polygon level and not
at the vertex level.
This rather simple solution makes Blender instantly one of the better tools to create Poser Morph targets (Full Body
Morphs) and conforming figures and clothing. Of course it's also adding a more complete support for the whole OBJ spec.
The patches are fitting well inside the established logic, have a minimal impact and are totally transparent to the
user. See the attached video (about 7 minutes long) for more details.
I noticed that the original scripts are formatted with tabs. I think it would be a good idea to follow the standard
Python recommendation and convert the scripts to use spaces. I didn't want to do it on my side as it would generate
a patch that replaces the whole file, not something that I wanted to do with my first submission :) But it would help
if people with access to SVN could do it.
Here is a short video that demonstrates the updates:

nobody seriously uses this format for graphics these days, and if they did, the export from blender is unlikely be to be useful, its just different views of the mesh edges projected into a 2D xfig file (quantized to int's too).
from Kevin Morgan (forTe)
imports images as quads in the 3D view
made some changes
- images that fail to import give an error popup rather then a script error
- extension input is only shown for batch directory importing
- extension comparison is now case insensitive
- importing images from "/" failed, (bug in Blender.sys.dirname), use os.path.dirname since os is needed for batch import in other places.
- disable Esc for quitting because escaping from the file selector would quit the script too.
Minor changes are...
- default size is smaller then it was but still too big IMHO, presets are huge.
- deselect all objects and make the new bolt active
- place the new bolt at the 3D cursor location
even though the format allows materials and textures to be written separately the textures wont load right in maya or 3dsmax unless each texture has its own material.
- when the attribute check function failed it didnt set an error raising a SystemError instead
- Rasterizer.getMaterialMode would never return KX_BLENDER_MULTITEX_MATERIAL
- PropertySensor value attribute checking function was always returning a fail.
- Vertex Self Shadow python script didnt update for meshes with modifiers.
There is a problem importing 3ds files where I cant find a way to check if the transforms are applied to the vertex locations or not.
Since 2.44 I made the importer assume they were not since you can manually remove transformations, but not reverse.
Nevertheless most 3ds files have the matrix applied, better not give a bad import by default.
Did some research and other 3ds importers (lib3ds for eg), have the same problem and just assume the transformations applied.
3dsMax imports both correctly so there must be a way to tell but I could not link it to the 3ds version or other mesh options.
Added an option to workaround this problem in rare cases where its needed.
- KX_GameObject.cpp & KX_Scene.cpp, clear the dict before removing the reference in case there is a circular reference.
- added DWG support, adapted Stani Michiels idea for binding an extern DXF-DWG-converter
The external DXF-DWG converter "dconvertcon.exe" 355kb comes from openDesignAlliance www.opendwg.org, is free, but not opensource, not GPL-compatible (can not be bundled with commercial programs), so must be downloaded and installed in Blender script folder by user. It is a DOS console application, can be started in background mode, works on Windows, and in Wine on Linux and OSX. Version 1.0 (2002) supports conversion between DXF<->DWG for autocad release: 2.5, 2.6, 9, 10, 11, 12, 13, 14, 2000, 2002.
