Overlay components: This is the standard function. Should the overlaying not be sufficient try one of the other functions.

Automatically calculate aligned rotation and position

Align parts position and rotation manually: Once you clicked on the button, the respective message is displayed: Please choose as base a feature of each part.

Once the second feature is clicked, positioning is automatically performed.

Remaining degrees of freedom for rotation and movement are signalized by respective axes and circles.

Original rotation and centered position (best fit)

In this example the parts are optimally aligned.
