Moving entire plan within grid

[HvF]

I somehow started my plan in the wrong location, added some rooms, deleted walls, added others and now I am ready with my floor plan but I am stuck somewhere on the grid. I would like to have my upper left corner of the floor plan to be closer to the grid's 0-point (x=0 / y=0) either by simply moving the ruler or by moving the entire floor plan. How can I do that?

Chose Select all or Select all at all levels in Edit menu, then drag and drop your design.

I have just installed and started using SH3D. I also wanted to move a whole plan but dragging and dropping doesn't have a snap to grid and there is no inspector as I drag to show me the coordinates .

Select All at All Levels doesn't seem to be working, lots of items are still not selected on the list on the left. Other options ?

It’s probably because you locked the base plan. Unlock it first.
