I downloaded a svg file from thingiverse. I scaled it down in inkscape so that the notches would match the thickness of the plywood. I saved it and reopened to check that the file contained what I had done. When I cut the design, it came out at the original scale. The parts were wasted, since the notches are too large.
As I recall from a recent post about changes to the software, the svg file format can contain transformation information and the data may not be an exact representation of what is seen in inkscape.
Has anyone else had this problem recently?
