Click a graphical manipulator, and then do one of the following:
- Drag the entity or graphical manipulator to translate or rotate entities in the selected direction(s).
- Enter a precise value in the microdialog and press Enter.
- Press Ctrl and select two locations to align an axis to a vector or three locations to align an axis to a plane normal.
Note: The Ctrl + click action is valid only for translation and rotation manipulators.To Do This Translate along an axis Click the X, Y, or Z arrow. Figure 3.
Translate along a plane Click the XY, XZ, or YX plane square. Figure 4.
Translate freely in 3D space Click and drag from the origin of the Move tool. Figure 5.
Tip: Use the icons in the microdialog to align the tool to a part or the global axes.Rotate around an axis Click a curved arrow. Figure 6.
Rotate freely Click at the tip of the X, Y, or Z arrow and drag. In the external aero setup environment, an axis line appears and the unresolved rotation is prompted on release.

Position the front end of the car at a certain distance from the inflow.
A similar technique can be used if a certain ride height, distance of the fender lip to the ground or underbody to the ground needs to be modeled. A reasonable positioning in the z direction, upwards, is when the wheels are slightly penetrating the ground of the wind tunnel.
