Hello

urgent issue please

create each as a separate project

then reference into a singular model

Eric's suggestion should work.

FWIW, we do have enhancement 65155 logged for multi-building column grid support.

But when I choose the grid tool to intiate a new grid for different building , it will superposed on the old one

What I mean , I have two building ,  first I create floor manager with two building,  then I create grid for building A,  when I create the grid for building B I find the previous grid still exist if icreate another grid it will be superppsed on the previous one and if I delete the previouse on how I can modify it aga

Right...  since grids are currently stored per-building + floor, and buildings are stored in the project's Floormaster file, I'm not sure if there's any way to have grids per building stored in the same project.  

That's why Eric had suggested using separate projects since that should allow different building + floor + grid.

do you mean that i  must have floor master "BB-floor master "  file for each buidling ?

yes you do

It depends on how you to that also.  If each building is the same project then only one BB-floor Master.

If each is a different project then yes one floor master for each.

Then also you can point all projects to the same BB_Floor_Master in your settings under Workspace preferences (all project) on within your Project user.ucf file for that project only (make sure to lock the variable)

each building is the same project , but each buidling has its own grid , what should i do ,

if i make floor master file for each building , is this will affect another sitting ?
