Testing TechDraw: SVG export failing ?

[HoWil]

Try adding this to the TechDraw section of your "user.cfg" and let me know what results you get.

Code: Select all

            <FCParamGroup Name="Rez">
              <FCFloat Name="Resolution" Value="10.000000000000"/>
            </FCParamGroup>

It seems to fix the problem here , but I don't know why

It resolves the problem

Is it possible to put this in master?

Again, many thanks,

Dear wandererfan,
Looks like the above set Resolution (or the internally done modification) changes the values for internally scaling the svg. I see a scaling factor of 10 when I open an exported .svg in Inkscape.

This results in x10 scaled .dxf when export the svg with Inkscape.
This parameter is usually set to 1.! Is is possible to set it back?

The FC page is drawn at 10px/mm, that's why the viewbox is 2970x2100. There's nothing in the generated SVG code that says "Scale=10".

I don't have that "Scale" groupbox in my "Document Properties" (Inkscape 0.91), so I can't figure out what it means. What happens if you change it to 1 and then export?

[HoWil]

If I change it to 1 the export works as expected... the dimensions in .dxf are the same as in FC and in the .svg.
This is my current workaround but I have to admit that each additional step in producing a final .dxf a source of error (i simply can forget it).

Is Resolution=1 no option? Is it the original setting?

I think so, look at the commit:

The. dxf outputs should be scaled in/from 0.91 too.

Thx.

Any other suggestions?
Thanks in advance,

dxf outputs should be scaled in/from 0.91 too.

They are scaled on output but there is no option in the gui to select scale or alter viewbox

Is Resolution=1 no option? Is it the original setting?

Resolution=1 will bring back your size problem.

The 12.04 machine already had a resolution=10 entry, the 16.04 did not.

Any other suggestions?

Not at the moment. Svg -> Dxf seems to be troublesome - google "inkscape dxf scale".

Usually it is not, as long as you use px as unit for export (see also e.g. http://www.inkscapeforum.com/viewtopic. ... 24&p=53129)

EDIT: Sorry for being so persistent. Previously I used drawing-wb where still all no scaling happens!
I really love techdraw and only want to make it a real 100% solid replacement for drawing.

Don't be. Persistence is good.
