栅格点在以图形方式定义对象时非常有用。 To open the settings of the grid, select "Grid" and "Work Plane" on the "Tools" menu. Alternatively, use the toolbar button
.
The "Work Plane" can be parallel to one of the three global planes: XY, YZ, or XZ (the selection is also possible by using the toolbar buttons
, that is, without opening this dialog box).
By default, the "Grid Origin" is located in the zero point. Use the
button to select a different point in the work window, or enter its coordinates. The
button enables you to define a new reference point.
In the sections below, specific options are available for you to adjust the "Grid Type" (Cartesian or polar arrangement), the "Number of Grid Points," and the "Grid Point Spacing," for example.
