TL;DR: Carbide Create is no the problem, in Adobe Illustrator, uncheck the “responsive” box when exporting SVGs.
SVGs import at funny sizes, but I never saw a clear answer on the forum that explained what exactly the fix was, or why it was happening. I had this issue with importing an SVG into Fusion 360. My SVG keeps on importing with an odd, seemingly arbitrary scale. I had read a bunch of the closed threads on the subject, and tried setting my ppi/dpi to 98. I hadn’t gone so far as to go back to using inkscape, but I was considering it.
The “responsive” setting is there to allow different screens to scale the vector graphics according to how they’re being displayed. Unfortunately, most of these programs seem to consider display on websites and print before any other uses. SVGs with “responsive” settings do not set height or width explicitly. But, when you turn “responsive” off, as you export your SVG will retain its height and width data. You can see this if you inspect the source of the SVG (XML is advertised as human readable!).
I hope this helps.
