Hello,
There appears to be a problem with .3ds import and epxport in the latest service release of Rhino 6.
I am testing some steps before implementing it in a script in Grasshopper.
So I am selecting an object, then in the command line:
_-export
test.3ds //the name of the file
then choosing the mesh options
And then manually importing the exported file back, the object imported has a completely different scale and rotation, and some times the import dialog shows that the file imported is fbx, it does not show the same dialog box that show up when doing the same steps in Rhino 5 (the one that includes the unweld option)
Update:
So i tried importing the same file to rhino 5 and it imported correctly, the problem seems to be when importing it back to rhino 6
