Create/Edit Grid Systems dialog

Opens with either:

the Edit Grid Systems tool is selected
Layout > Grids > Create/Edit is selected

Only unique Grid Systems need be created. It is not necessary to create a separate Grid System for each Layout Type if the Grids are identical between levels. A Grid System may be used by more than one Layout Type, and a Layout Type may use more than one Grid System.

Note: When databases are converted from versions of the program prior to V7.0, the Grid Systems are automatically created from the Grids in the model. A separate Grid System is created for each layout type, and the label "Converted From:", with the layout type name, is given.

Setting	Description
Grid System Label	Type a unique label used to identify the grid system.
Grid System Type	Select either an Orthogonal (i.e., Carteisian) or Radial (i.e., polar) grid.
X / Y offset	The distance of the local grid system origin from the global origin.
Rotation	Angle between the local Grid System and the global coordinate system, measured counter-clockwise.
grid list	A list of all the grids in the model.
Add	Click to add a new grid to the list. Active once a new Grid System Label is typed.
Delete	Click to delete the currently selected grid. You may not delete a grid system currently assigned to a layout type.
Change	Click to save changes to the label, offsets, or rotation. If the offset or rotation values are changed, the entire Grid System will move, and any structural elements associated with those grids will move as well.
Edit Grids	Opens either the Orthogonal Grids or Radial Grids dialog (depending on the current grid selection type).
