Please see below, it is the C-hub I have designed for my model car. the picture as you look behind it, I want to slant 5 degrees to give me another option. So the top half will be 5 degrees further forward than the bottom half.
Posting the TC file would be easiest .... From what i see, What your asking can be done ... but the method depends on "How the model was created".
1 way is to separate the Bottom & Top portion and recreate the Vertical element at 5 degrees >> Then 3D Add it back together.
Separate Top & Bottom / Draw 5° lines at key points of bottom to top / Shift Top to end of 5° line / Node Edit Vertical portion to Top / 3D Add it back together.
If your just trying to Turn the Whole Model 5° ....
It is done via the Rot X, Rot Y Rot Z fields.
Ensure these Fields are Ticked for viewing via ...
SELECT / RM click > Toggle 3D / Rm click > Selector 3D Properties / (Inspector Bay) Tick Rotation X Y Z
Rot X Y & Z field boxes should show up at the bottom of your screen.
