-
In the Name box, enter a name for the grid you want to create (for example Grid Skeleton).
-
In the Mode list, select Relative or Absolute to define the grid construction mode.
In the relative mode, grid planes are positioned with respect to each other. Moving a plane impacts other planes offset from that plane. This is the default mode. In the absolute mode, grid planes are positioned with respect to the grid origin. Planes can be repositioned independently of one another.
-
Under the Origin area,
enter absolute coordinates.
You can select a point in the 3D area to define the grid origin.
-
Optional:
Under the First direction in XY plane area,
do either of the following:
-
In the Cartesian tab, enter H and V coordinates to define the local x-axis.
- In the Polar tab, enter an angle to define the polar axis.
- Select a line in the 3D area.
-
To specify grid coordinates, do either of the following:
- Select Cartesian, and specify the distance between grid points and number of points along x, y and z axes.
- Select Polar, and specify the radius, amplitude, spacing along the z-axis, and the number of grid points in each case.
Note:
You can expand other coordinate sets to enter up to three more different combinations to define your grid.
