Dear sirs
I'm trying to modify weights in flage/valve database in folder LIB_M.
In Caesar II configuration I set "Specs in CII, Data in CW", selected CADWorx database and saved

Caesar II user manual states:
"Individual lines in the file list the library subfolder to the LIB_I or LIB_M folder, depending on whether English or Metric units are in effect) [...]".

Where can I set if I am using English or Metric units?
Line 4 of Cadworx.dat?
Unit file?
Thanks a lot for your help.

I found the solution.
I need to change the name of the class in Cadworx.dat file-
For example, I have to change 150 in 150_M

Thank you
