Parallel To Axis

Dialog boxes where you can set orientation dependencies            Shared Dialog Box
Orients an entity parallel to a chosen axis on a construction frame by making an axis on the chosen entity dependent on an axis on the construction frame. Learn about Construction Frames.
 
Note:  
Because hardpoints have no orientation, you cannot use them to define this type of orientation dependency. Learn about Hardpoints.
To determine the orientation of the other two entity axes, you use the two remaining construction frame axes. Therefore, if you specify the entity's x-axis as parallel to the construction frame's - z-axis, the entity's y- and z-axes would be oriented according to the right-hand-rule along the construction frame's x- or y-axes (in this case, the entity's y-axis would be parallel to the construction frame's y-axis, and the entity's z-axis would be parallel to the construction frame's x-axis).
 
For the option:
Do the following:
Construction Frame
Enter the name of the construction frame needed to create the parallel orientation dependency.
Axis on Entity
Specify either the z- or x-axis as the entity axis that will be directly dependent on the construction frame orientation.
Axis on Frame
Specify the construction frame's axis that is the basis for the entity's dependent orientation.
