dxf save for autocad does not translate correctly

[Brian Pahl]

I am using the windows xp, and have installed inkscape version .46, .47, and the newest relaese, and have had same issue.

Whenever I creat something in inkscape, it will not translate or display correctly in autocad when it is saved as a dxf. It will bring in all appropriate objects, but any translations done to text will not display correctly.

For example, if I create a circle and place text onto that circle, then do a free transformation such as move or rotate, it will not show up like this in autocad. It will display the text as it eas before the transformation.

Also, if I try to save the file in inkscape as it is still open in autocad, it will come up with an error, and after that the file will no longer open with inkscape, and sometimes even with autocad.

I am using autcad 2004.

I also saw a post on the net form someone that had 4 files to install into the share/extensions folder that created better dxf files for autocad, but still similar issues.

I fix for this would be greatly utilized.

bug 60472 seems like same bug

can you post a link to the files you found so I can look at them?

[Alvin Penner (apenner)]

sounds similar to Bug 585021.
could you try this procedure:
- Edit->Select All
and then use :
- Path->Object to Path
- then, with all objects selected, force a bit of a translation by selecting the entire group and hitting the up arrow once. If all goes well this should remove the transform elements from the diagram. If this does not work, could you attach the .svg file?

I attempted the select all and save, and still no luck. I also tried grouping objects with same results.

Attached is the dxf and svg files.

I found a few different links to similar files. They were listed as .46 version files. I am using .47 versoin of inkscape, and these did not work properly. I also ttried installing .46 with similar results. Not sure if they could be tweeked, or the original files could be tweaked to better the dxf. output.

I also attached an example of the dxf file and the svg file problem I am experiencing.

[Alvin Penner (apenner)]

confirmed, the method outlined in comment 2 does not work in this case. It appears that the problem is that the transform has been applied to an entire group, not just individual objects, and it is a rotation not a translation.
    As a work around I used the following method:
- Edit->Select All
- Object->Ungroup
- export to dxf
this led to the attached result, which appears to be correct.
- over the next month or so I will look at the code to see if it is feasible to automatically take into account the effects of the transform element.

[Alvin Penner (apenner)]

attached is a new version of the file dxf_outlines.py, which takes into account the effects of the transform element. In order to use it, you will need to copy it into the directory Inkscape\share\extensions

could you try this and see if it helps?

[Brian Pahl (dscsuperf)]

It seems to be working much better. Thank you very much for your time.

[su_v (suv-lp)]

@Alvin - could you check with these related reports which ones can be closed as well (or maybe linked as duplicates for easier bug management)?

Bug #606071 “DXF Converson distorts image created in SVG”:
Bug #585021 “save as .dxf does not handle transformations”
Bug #487648 “Problem with DXF save files”

(possibly all duplicates of bug #487648? - which is probably not strictly 'Invalid' with regard to user expectations, or layer transforms which are not accessible from within the normal GUI)

and:

Bug #600472 “file saves with file types that are written in python have missing object or misplaced objects (dxf and hpgl)” - AFAIU at least part of the reported issue is solved with your just committed changes to 'dxf_outlines.py'.

[su_v (suv-lp)]

@Alvin - would you consider it save backporting the DXF export fix for transformations to the 0.48.x branch so that the latest improvements get released with 0.48.1?

The changes are in revision 9640 (transformations, bug #600473).

[su_v (suv-lp)]

backported to inkscape 0.48.x in r9721
