To Create Datum Points Offset from a Coordinate System
1. On the
Model tab, click the arrow next to
Point, and click
Offset Coordinate System. The
Datum Point dialog box opens.
2. In the graphics window, select a coordinate system to use for points placement.
3. In the Type list, select the coordinate system type. Choose from Cartesian, Cylindrical, or Spherical.
4. Start adding points by doing one of these actions:
◦ Click a cell in the points table.
◦ Right-click the graphics window and choose New Point on the shortcut menu. This adds another row to the points table.
The new point appears in the graphics window. The point has a drag handle that looks like a white rectangle. The new point is dimensioned along the designated axes.
5. Adjust the point’s location by doing one of these actions:
◦ Type the point's coordinates for each of the required axes. For example, for the Cartesian coordinate system, you must specify distances in the x, y, and z directions.
◦ Drag the point's handle along each of the axes of the coordinate system.
6. To add another point, click the next row in the table and type the point's coordinates. Alternatively, click Update Values and enter values in the text editor, with each value separated by a space.
|  To add points using the text editor, the point’s table must have at least one value. |
7. When finished creating points, you can accept the points and quit by clicking OK, or you can perform one of these actions:
◦ To save the points to a separate file, click Save. Specify the file name and location.
◦ To convert points to a non-parametric array by removing dimensions, select the Use Non Parametric Array check box.
| You can convert a non-parametric array back to a parametric array by editing the feature definition and clearing the Use Non Parametric Array check box. |
