Step 1: Axis position
select left door (its axis is closest to the hinge point)
open the DC attributes. choose rotZ, place a value, the door will rotate about this axis at the inserted axis point,
you will note that values above 180 become negative co-angles
the rotation as per right hand rule for vectors
and for the right
that is because the axis and insert point is in line with the latch
so first line the axis with hinge points (right click menu)
then work the positions you wish to rotate from - to
then you can use the onclick attribute and add
animateslow(“RotZ”,0,90) to right, animateslow(“RotZ”,0,-90) to left
