local transformation, dont get it..
is it possible 2 use channel/attr. editor's translateXYZ 2 set LOCAL transformation?

like: moves from frame #1 to #10 along axis x
2.#10-#15 box rotates along Y, so object's x and world x r not paralell.

is there any way, to use channel's tx entry 2 move box along object's axis? if i use move tool with objects' axis setting, that changes tx as world coords.

in other words, can i set up tx,ty,tz 2 use object axis movement? maybe,i've totally missed the concept..and cant

i use tz in expression, thats why i need it..

AFAIK, translate channels are in world space. To move in object space, you need to use the Move mel command (it's in the MEL commands documentation). Not sure if this will work in your expression, but it's something to look into.

thx dannyngan, found it, but i would like to avoid to script the whole sequence..i try to stick with only expressions, if its possible. maybe my whole concept is wrong, how could i do the following example:

-barrel rolling to one direction, than turns 30deg, and continues rolling along the new angle. expression calculates the roll and wobble of the barrel shape. no path. how should i do it?

as i add a parent, the channel controls use local axis ,but rotation after child transformation wont be correct, of course.

i feel its too simple, i miss something..
