How to rotate a dsc mesh 90 degrees?

[john71]

Help!

How can I rotate a dsc nebula mesh a "normal" 90 degrees?

This data -> Axis [-0.679381 0.221716 -0.699488] Angle 196.475 is perpendicular.

Could you give some more details? In what direction do you want to rotate your model 90 degrees?

This data (Axis [-0.679381 0.221716 -0.699488] Angle 196.475) places the mesh in the target galaxy (Milky Way), but the mesh has a wrong orientation. So the end result is perpendicular to the Milky Way plane.

I want to rotate the mesh 90 degrees to be on the plane of the Milky Way.

This is the mesh now:

My target state:

I cannot rotate the 3ds mesh in Anim8tor or Blender, so I have to use the same cmod mesh.

I cannot use the tool, because I don't understand the math. Someone should explain it with this data set and with this problem...
