rotation axis origin and direction
 

HI, I got a problem on making rotating wheel.
I set rotation origin as (3, 2, 5) and the rotating axis Parallel to z axis.
so, how can i set rotation direction??
It suppose to be (3, 2,7) ???? or just (0,0,1)
need your help

If rotation is around the z-axis, your axis should be (x y z) = (0, 0, 1).

thank you for answer.
rotation axis is not z-axis but the axis parrellel to z-axis
then rotation direction should be (0,0,1)??? not (3,2,7)???

yes, because you already give the origin coordinates, so if you use origin (3,2,5) with axis (0,0,1) the axis will be parallel to z, but not on z.

If you would use (3,2,7) as axis direction, it would not be aligned with z at all, instead pointing away from it slightly in the positive x and y direction.

then ,my problem solved now

thank you!

best regards

Glad to be of help!
