[. . . ] You may save any of the grid information as the default setting so that when you start a new model that information is already there. To do this, simply enter the information that you want to save in the Drawing Grids Dialog, check the Save Current Settings as Defaults box, and then click the OK button. Rectangular Drawing Grid The rectangular drawing grid is defined by increments in two directions. The Drawing Grid Origin is where you want the grid increments to start. The Rectangular Grid Increments are the distances between the grid points or lines in two global directions. 70 RISAFoundation v3. 0 Graphic Editing You may use symbols such as "@", "/" and ", " when entering the drawing grid increments. The "@" entry may be used to specify multiple, equally spaced, grid increments. For example, if you wanted 7 increments at 10 units each, you would type "7@10" in the increment field. The "/" entry subdivides a larger increment into smaller equal increments. For example, the entry "12/4" would create 4 increments of 3 units each. Use commas (", ") to enter multiple increments in the increment field. For example, if you wanted to define increments of 3, 4, 7 and 2 units, you could enter "3, 4, 7, 2" in the increment field. Once the drawing grid is specified and displayed in the model view, it will provide snap points while drawing your model. Skewed Drawing Grid The rectangular drawing grid can be skewed by specifying a skew angle. This option is available in the Rectangular Grid Increments section of the Drawing Grids Dialog. This skew angle will allow the creation of a regular rectangular drawing grid, but displayed in the model view at the specified angle, inclined from the global axis. Radial Drawing Grid Increments in two polar directions define a radial drawing grid. The Drawing Grid Origin is the point about which the grid will rotate. The default is at the global origin (0, 0). The Start Angle defines the angle from the global axis that the first spoke will be drawn. The Angle Increment controls the number and angular spacing of the spokes in the grid. The Radial Increments controls the number and location of the rings in the grid. General Reference Manual 71 Graphic Editing Relocating the Drawing Grid The origin of the drawing grid may be specified in two ways. The first is to enter the exact global coordinates for the origin. This can be done by entering the values in the Horizontal and Vertical fields of the Drawing Grid Origin section. The second option is to specify the origin by clicking on an existing point in the model. This option is available by checking the Click on a location to relocate Origin box, clicking the OK button, and then clicking on the specific location in the model view where you wish the drawing grid origin to be located.
