SVG Export resolution AD

[DarkClown]

I'm struggeling a bit with the export size of SVG files.
When I export slices of the size 100px x 100px (unsing document settings) and re-import the SVG files they come up with a size of 416.7px x 416.7px. Since we are looking at px (device independent units) this should be completely independent from the document res. (dpi).

Anyone got a clue what to do to get a SVG file same as the original size?

Cheers,
Timo

 

And yes, I'm aware that SVG files/vector files are lossless sclable - so you can always argue "Who cares" ... but for certain purposes this is a problem (e.g. CAD systems)

Could you share a sample file that illustrates the problem?

I just created a new document, pixel units, 100x100 pixels in size, added a curve and exported to SVG. I can open that SVG and everything is the correct size, as expected (attached for your reference)

Thanks,
Matt

300/72 = 4.167

@MattP drag the exported svg back into the document it will import as 72 dpi.

 

 

Definitely true - but this is placing a 72dpi SVG into a 300dpi document. I'm happy with this behaviour as it is correct (edit: at least, arguably, lol!) - but if you open the SVG you'll see it create a 72dpi document at the anticipated 100x100 pixel size

As Alfred points out, this does imply that the original document is at 300dpi. Try working from a 72dpi document - I'm assuming it will then export as intended?

OK, that solves the problem ... Looks like the dpi information is not exported within the SVG file so AD is not able to determine the proper dimensions and assumes 72dpi.

What brings me to another nasty behaviour: The pure SVG file is nested in a folderstructure that limits visibility of the exported svg to the artboard. Is there a way (setting) to prevent that and just get the desired SVG - unnested in folders and curves?

Draw a square of 100 x 100 mm in an empty AD document, export SVG with default settings (no rasterisation).
Then place the SVG in the same document. it is so huge that it can't even be selected or moved.

The page borders are part of the imported SVG, that should not be either.

I export SVG vector files for CNC software (Carbide Create) and always have to scale down. Not tragic of course. With Illustrator the size is ok.
