Grids can be moved a specified increment using the Move command in the Edit Grids command. When the Move command is used, the resulting grid coordinate is the initial coordinate plus the specified increment. For Orthogonal grids (X and Y), Increment is the distance to be added to or subtracted from the grid coordinate. For Radial grids, Increment is the angle to be added to or subtracted from the current grid angle. For Circular grids, Increment is the distance to be added or subtracted from the radial distance.

Grids are moved by first selecting the grid, entering an increment by which the grid will be moved and then clicking the Move button. Multiple grids can be moved simultaneously by selecting more than one grid from this list before issuing the Move command. Multiple grid selection is done by holding down the <Ctrl> or <Shift> keys while selecting grids from the list. <Ctrl> selects only the individual grids that are clicked on; <Shift >selects all grids between the previous selection and the current selection.

Grids can also be moved using the Change command described previously: select the grid, enter a new coordinate, and select Change.

Entire Grid Systems may also be translated or rotated using the Create / Edit Grid Systems command. To translate a grid system from its current position relative to the global coordinate system, enter the desired value in the X-Offset and/or Y-Offset edit fields. To rotate a grid system from its current position relative to the global coordinate system, enter the desired value in the Rotation edit field.

When grids are moved, any columns associated with those grids are automatically moved as well. In turn, any beams framing into those columns are moved, and any beams framing into those beams are moved. Thus beams are stretched and rotated as necessary to maintain their connection to the supporting members. When a girder is stretched or shortened in this way, the spacing of the supported beams is modified to maintain the relative spacing. For example, if a girder supporting beams at third points of its original length is shortened or elongated, the beams will be repositioned so that they are supported at the third points of the new length. They keep their relative spacing rather than their absolute spacing.

It is important to note that if a column does not fall on a grid, it will not move, even if the entire grid system is moved. Also, items such as point loads, surface load polygon vertices and deck polygon vertices that do not fall directly on a beam or column will not move. Those that fall on beams or columns will move. After a grid or grids have been moved it is important to verify that the resulting configuration of members, decks, loads, etc., is correct. The DataCheck is useful in finding any problems that may have occurred due to a move.

Since grid systems can be used by more than one layout type, any changes made to the grid system affects the framing in every layout type that uses that grid system.
