DXF Converson distorts image created in SVG

[jim sutton]

I continue to receive reports of DXF file distortions from the machinist assisting me in creating a medallion.

My design in SVG looks like this (saved as png):

However, when SAVED AS DXF and loaded into CAMBAN program, the DXF displays like this with many parts rearranged:

Here's the SVG file:

Inkscape v0.47 OS WIN7 Ultimate 64bit

Any idea what might be going on here? All help is appreciated; my time on this project is running out.

attached is a version of the dxf output I obtained by using a combination of the methods of Bug 600472 and Bug 600473. Basically what I did was to select each group and use the procedure Object->Ungroup in order to remove transform elements.

I am working on a permanent solution to this but it may take a few weeks to complete, it is a bit more complicated than expected.

a new version of the file dxf_outlines.py is attached to Bug 600473, https://bugs.launchpad.net/inkscape/+bug/600473/comments/6

this will take account of the transform element. Could you try this and see if it helps?
When I run this on the file DharmaShield8.svg the text element '2010' is not output.
In order to output this text, it is necessary to select the text and use the menu item Path->Object to Path.

I found another FIX resource:

ttp://www.bobcookdev.com/inkscape/inkscape-dxf.html<http://www.bobcookdev.com/inkscape/inkscape-dxf.html>

He developed it for version .46 it says.

And this update to Bob Cook's work:
http://tim.cexx.org/?p=590

I used this latter update and followed ~suv 's instructions to correct my
most recent work and the problem's have disappeared. I applied the clean up
instructions and loaded the script update so I cannot attribute the correct
to either singular source. I would say the problem has not resurfaced,
though.

To clarify: this refers to my comments in the InkscapeForum topic:
<http://www.inkscapeforum.com/viewtopic.php?f=5&t=5604>
and specifically to the latest which deals with a mix of layers with and without a transform attribute (some have been added after the page was resized, some are older):

I would not recommend to install/mix different DXF output extensions (written for older Inkscape versions) unless you verified that
a) it does not overwrite more current versions of e.g. inkex.py
b) it is properly adapted to run under 0.47 (e.g. the specs for the inx files have changed)

[Alvin Penner (apenner)]

anyone interested in trying the new version posted at Bug 600473, comment 6?
I believe this should automatically take into account any transform elements that are present.

[su_v (suv-lp)]

The three versions of the DharmaShield8.svg file attached to the forum topic export correctly with regard to preserved transforms on groups and objects with the new version of dxf_outlines.py from bug #600473 (verified by viewing the DXF file in QCad).

[Alvin Penner (apenner)]

thanks ~suv, much appreciated.

[jim sutton (jim-sutton)]

Thanks ~suv, very much.

- a new output routine to deal with the effects of transform elements has been posted in Bug 600473 comment 6
- https://bugs.launchpad.net/inkscape/+bug/600473/comments/6
- could you indicate whether this resolves the issue for you?
- if there are remaining problems which have not been addressed, would you be willing to file them as separate bug reports?

Fix confirmed with Inkscape 0.48+devel r9819 on OS X 10.5.8
