depends on what I have to show... .
even more than one.
However, as I'm a bastard inside, as the explosions I use them to give them to customers in the vex of drawings together and as I don't want them to cover my machines... Sometimes I do them in perspective!
considering the three modes of views, isometric assonometry that provides an angle of 30° compared to the horizontal axis of the solid represented by both sides, a dimetric assonometry that provides an angle of 7° degrees on one side and of 32° on the other than the horizontal axis, axometry cavalry that previews an angle of 45° of the solid compared to the horizontal axis, I would choose the view I hope I've been helpful!
