I am following a tutorial to learn Blender and I have a rotation problem.

All the rotation values of my object are reset to 0 but it is still rotated. Apparently rotations made in Edit mode apply differently but I am now unabled to reset it to zero.

I tried ctrl + R and Clear all user tranformations and nothing seems to work.

Thanks

  • $\begingroup$ if you've rotated your object in Edit mode, you won't be able to get back to the original rotation position (well actually you can but you will have to use some complex tricks). If you reset the rotation to zero with alt R it will only reset the rotations you've made in Object mode. And also, if you've applied the rotation in Object mode with ctrl A, you also wont be able to reset (again, except with some tricks). $\endgroup$ – moonboots Sep 24 '18 at 17:05
  • $\begingroup$ I would like to know about the tricks. Or how to avoid it next time. $\endgroup$ – Manspider Sep 24 '18 at 17:19

    $\begingroup$ How to avoid it: if you want your object (cube for example) to remain orthogonal to the grid, don't rotate it in Edit mode, only rotate it in Object mode, and don't apply the rotation. This way you'll always be able to go back to the original position with a simple alt R. About the trick: I'll try to find it. $\endgroup$ – moonboots Sep 24 '18 at 17:37

So, to sum it up:

If you've rotated your object in Edit mode, you will only be able to get back to the original rotation position with a trick like the one I'll explain below. In Object mode, if you reset the rotation to zero with alt R it will only reset the rotations you've made in Object mode, not the one you've made in Edit mode. And also, if you've applied the rotation in Object mode with ctrl A, you also won't be able to reset (again, except with the trick like the one below).

How to avoid it: if you want your object (cube for example) to remain orthogonal to the grid, don't rotate it in Edit mode, only rotate it in Object mode, and don't apply the rotation with ctrl A. This way you'll always be able to go back to the original position with a simple alt R.

Now, the trick to align a randomly rotated object (cube for example) to the grid

as explained by refa42 in a youtube video: https://www.youtube.com/watch?v=0pfTDzAaXp4

  • $\begingroup$ In short.. freeze the mesh by hooking it, allowing you to transform the object (axes) any way you like without transforming the mesh associated with it. I can't believe I haven't come across this complete replacement for the transform pivot point function in other applications before. Other methods are so complicated / arbitrary / non-general by comparison with this one. $\endgroup$ – Robin Betts Mar 26 at 8:02
  • $\begingroup$ I don't even remember how this one works, this is the kind of tricks that gives me headache, fortunately we don't often need this kind of operation... :) $\endgroup$ – moonboots Mar 26 at 9:04
