Color By Service in AutoPLANT Piping

Hello,

I am using AutoPLANT SS4 on AutoCAD 2012.

In an AutoPLANT Piping model I change the color to be by service in the drawing preferences.

I defined the service color in the color.ini file in 2 places: \%Project_Root%\Config\ and in C:\Program Files (x86)\Bentley\Plant V8i\Config\mmetric.

I defined a new servie in those file Alex=2 and defined a new service Alex in the model. I see that the colors are wrong (not the color 2).

It seems that the program is taking the colors from else where.

I need to define myown colors to my own services.  How can I do it?

Thanks

Alex Bekker
