I exported data (save data) and successfully saved a set of contours, but when I import them into a cad package, the data seems to be scaled by a factor of 100. (a point in paraview would be at 0.119 (meters) and that same point is at about 1.2 (mm, probably assumed?) in the cad package).

ParaView doesn’t specify units. You can scale your points down by a factor of 100 using the **Transform** filter and then export again.

I assumed it wouldn’t specify units: That’s why I’m surprised that the measurements don’t match.
Why wouldn’t the points be the same?\>

Perhaps your CAD package makes assumptions about units in STL files.

I saved it as a non-binary, and confirmed that the export is correct. No idea why the Fusion360 import decides to scale the points.
