Hi Ken,
Thanks for letting us know about this issue.
It would really help to get a model from you.
We can look at the issue and try to figure out a linetype scale that works for you.
Brian is right on about scaling the linetype by the conversion factor.
This is interesting. I wonder if the lines in the block are set to “linetype” by parent, so the linetype of the block reference layer is used.
If you prefer to send me the files or dropbox link directly, my email is mary@mcneel.com.
Thanks for your help.
Sincerely,
Mary Fugier
