HFSS15: Creating an Offset and Rotated Relative CS

To create a new relative CS that is both offset and rotated from an existing CS:

1. In the history tree, select 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 Both.

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.

5. Specify the x-axis by selecting a point on the axis in one of the following ways:

• Click the point.

• Type the coordinates of a point that is relative to the origin in the dX, dY, and dZ boxes, where d is the distance from the previously selected point.

6. Specify the xy plane by selecting any point on it in one of the following ways:

• Click the point.

• Type the coordinates of a point that is relative to the previously selected point in the dX, dY, and dZ boxes.

You do not need to specify the z-axis. It is automatically calculated to be at a right angle to the y-axis.

The new relative CS is created. 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.
