Edge softening units when importing

If an object is made in one Rhino file using millimeters and then imported as a block into another file which is centimeters, then all edge softening of the imported block is off.

can you give a file and steps to reproduce?

Yep, I can imagine that is the case - the edge softening is applied ‘on the fly’. I do not know if there is any hope for overcoming this in the short term…
