HFSS15: Creating an Offset Relative CS

To create a relative CS with an origin that lies a specified distance from another CS’s origin:

1. In the history tree, click the CS upon which you want to base the new relative CS, making it the working CS.

2. Point to Modeler>Coordinate System>Create>Relative CS.

3. On the Relative CS menu, click Offset.

4. Select the origin in one of the following ways:

• Click the point.

• At the lower right of the modeler window, use the drop down menu to select the system for expressing coordinates (Cartesian, Cylindrical, or Spherical), select either relative or absolute coordinates, then select the units, and type the CS origin coordinates in boxes.

To select a point that does not lie in the current plane, use the Movement Mode commands on the shortcut menu.

The new relative CS is created. Its origin has moved from the previous working CS, but its axes remain the same. It is listed in the history tree under Coordinate Systems. It automatically becomes the working CS; objects that you draw hereafter will be based on the coordinates of this relative CS. Default planes are created on its xy, yz, and xz planes.
