The issue is that, the managed workspace including gridlines.txt & GridModels.dgn was ready and it really works for users to refer the Gridmodels or produce isometrics. But when someone else was going to modify the Grid system, it is found that the Grid systems box can not reflect the right information from gridlines.txt & GridModels.dgn. It seems a one-way function. We have to input the grid date from top to bottom manually again according to gridlines.txt.
Then I checked the help file. it says about grid Import/Export, something like the picture below form the help file.
But I can't find a access to this function. If this does not exist, how can I make the Grid systems box synchronize with the gridlines.txt.
Thx, man
