Feet Inches to Metres

Which design file units are you referring to? is it MicroStation design file settings?

Both should be the same to prevent any strange result. So file settings for MicroStation and Project Options for Rail Track

Thanks for the reply. When I am using hori multiple regression analysis, even though the numbers are correct in metres, the power rail track displays suffice as ft. Do you know where I change, please?

Thanks in advance

If it does display annotations in the drawing with suffix ft then it is in the Display Regresssion points settings and preference.

But if you've got all in imperial since the beginning, it is most likely you are using the wrong xin file.

You should configure File>Project Defaults to use the correct XIN from C:\Program Files (x86)\Bentley\PowerRailTrack V8i\PowerRailTrack\InRoadsGroup\data
