Request about Official documetns for ds cordinate system

kitakoredaz

I still have not gotten clear knowledge,
about daz cordinate system. As for me, it is really diffiuclt to understand .

I know, usuall Groval or local cordiante. but when I rotate some thing in daz studio,
by parameter of each rotation. and When I make hieralchy and rotate each part,
I can not clear see each axis direction.

there are many cases, eg,, when I use joint editor, then change orientation , how it work
and how the rotation axis are changed,,,

I know when I need to see true axis direction for parameter ,
I must change cordinate system, as ( Use world Cordinate/w local rotation)
but these axis direction which I can see with moving parameter , are simply really strange for me ^^;

eg,, when I set the obj rotation order Y-Z-X, in joint editor. and tweak oriantation in joint editro.
and rotate by parameter tab,

about Y rotation axis (first rotation ), rotate by boundary box Y axis ( local Cordiante Y axis)
about X rotation (last rotation) rotate by gloval Cordinate X axis (+ Oriantation of the node changed in joint editor)
about Z rotation order, (second rotation order,) I can not understand how the axis direction are calculated.

Why daz studio can not rotate objs, or nodes more easy way?
eg, in other 3d tool, if I use groval cordinate, I can input each value,

or if I need to rotate obj or node , as rocal axis, I simply input each value with local cordinate.
I know I can do it approximately by universal or rotate tool. with snap,, but not precisely.
DS do not offer us imput value for current rocal axis.

and please add, one more option which can see the rocal node rotation axis, and Parameter axis, at same time.
even though I change bone visible, It can only show bone but not each node rotation axis,
I often need to change joint editor tool but it can not show me parameter rotation axis.
