Since Updating to U10, my scaled custom linestyles that are defined in a RSC file with a UOR of 1000 are now displaying 1000 times smaller. See screen captures below.
When placing the same LS in the same model, I now have to scale them 1000 to look correct.
LS scale in the model are scaled using Annotation Scale.
Example of break line CLS not displaying correctly.
