Hi,

One user ask me about a file which keeps switching from Metric to Imperial. I spend some time on investigation and got more interesting problem.

In case of the DWG file from the user the problem was solved by resetting MEASUREMENT variable from 0 to 1. No problem. But lets open a metric file from AEC Content folder. Check MEASUREMENT. It is 0! But the file behaves correctly - it is always in metric, no switches to inches through AEC related commands! So, there is another setting which affects unit switches.

So, what is the setting which overrides MESUREMENT=0?
