The Generate Grid dialog box is used to help
control the generation of a grid
using objects (p. 17).
It is displayed by selecting Grid|Generate Grid... or
pressing the Generate Grid button .
Before it can be used, there must be at least one polygon on the top
view of the model for which use to set element grid size
is true and at least one polyline or polygon on the front or side views
of the model for which use to set element grid size
is true. (See “Object Properties Dialog
Box” on p. 49.) The
“Calculate grid angle automatically” checkbox determines whether or not
GoPhast will calculate a grid angle or use an angle supplied by the
user. If it calculates the angle automatically, it will specify
the angle so that the area of the grid is minimized. If it is not
calculated automatically, the user must specify the grid angle (in
degrees) in the Grid angle edit box.
In some cases, it may be desirable to have a gradual transition in element size. The can be achieved by checking the Smooth grid checkbox in the Generate Grid dialog box. If it is checked, the check boxes for rows, columns, and layers determine whether grid smoothing will be applied in those directions. The “Grid smoothing criterion” determines the maximum ratio allowed between adjacent elements.
