To fix this (when exact dimensions matter), you have to scale everything by the ratio of the two PPIs - scaling everything up by 106.667%. Hence everything that you draw in Inkscape comes out about 6% too small in CorelDraw. So if you draw a 1 inch long line in Inkscape - it'll be stored as a 90 pixel line in SVG, which CorelDraw will convert to 0.9375" (90 pixels/96 ppi) as it loads it. Unfortunately, Inkscape uses 90 ppi and CorelDraw uses 96 ppi. In order to allow you to work in real-world units, programs have to assume some arbitrary number of pixels-per-inch (PPI) for the device you are using. However, the SVG standard requires that dimensions, positions, etc are stored in abstract units ("pixels") - not real-world units like inches or centimeters.
These are not a standard part of SVG and are ignored by CorelDraw. (Advanced users can use more colors for more things.but if you know enough to do this, then you don't need me to tell you how!) Anything you want to raster should be in monochrome/greyscale.
#INKSCAPE VECTOR INTO SVG DRIVERS#
To be fair, none of these are Inkscapes' fault - but rather shortcomings in either the SVG file format, in CorelDraw or in the Laser Cutter drivers themselves. However, there are a few "gotchas" to be aware of.
#INKSCAPE VECTOR INTO SVG PC#
Since you'll need to transfer the files to the laser cutter's PC (which has a copy of CorelDraw) - this is no big deal. Hence if you want to do your design in Inkscape, you have to import the resulting SVG files into CorelDraw for lasering. Unfortunately, you can't drive the laser directly from within Inkscape because it rasterizes all of the vector data before sending it to the device.
#INKSCAPE VECTOR INTO SVG MAC#
One good/cheap option is to make your drawings in SVG format from " Inkscape" which is free/OpenSourced and runs well under Windows, Mac and Linux. But because Corel Draw costs $400 for the mainstream version and $99 for the student edition - you'll probably want to do your design work in some other piece of software.
We generally operate the Blue Laser Cutter from within Corel Draw.
