Save Text Scale

[uniken1]

Perhaps I'm not understanding what you mean by image text is broken?

all text items having the font size less than 1pt are converted to 1pt font size, and this makes the picture ugly.

Yes, like topic subject "Save Text Scale"

After some test I have found only one way(thanks Nikolay for Inkscape and EMF):
I ungrouped cisco 1841 object;
delete all text;
add some needed element;
then in Inkscape write text;
save as emf with checked "convert texts to pathes"
and copy/paste from Inkscape to Visio;
Text is scaled!!!
And then group all again.

PS: Cisco 1811 looks good, and its simple scalable!:
