How to easily put all transformation, rotation and scaling values on 0 0 0?

Hello,

sometimes there is the situation, you want to undo all transformations,rotations and scalings on an object.

It means NOT freezing the object "Reset XForm", it means that the object is moved back and oriented back and scaled to 000 of it's local space.

Like manually typing 0 in all three values for absolute transform, rotation and scaling.

Is there a command for this?

In Maya - sorry again for always citing Maya here - this is "reset transformations" and can be applied to mulitple selected objects at once. Very handy and often used...

Thanks

Setting absolute values back to 0

Right-clicking on any spinner (the up/down arrows) will always change the value to 0 or the lowest possible value (ex: Box segments minimum value is be 1).

@BenediZ

If I understand your question you want to be able to return to the transforms (scale, rotate and position) of an object at the time of it's original creation in the scene, right? Like being able to undo for just a specific object the history of all transforms on it? Like the construction history (I think it is called) in Maya? So the general scene Undo function wouldn't work (and is not stored anyway after you quit max).

If so, am pretty sure that there is not such a complete object-specific transform history that is stored in a max file. However, in the animation menu there is "Set as skin pose" which will store the objects scale, rotation and position transforms. If you later click on "Assume Skin Pose" in the animation menu, your object will be restored to the state of its transforms when set the skin pose.

I'm not sure that I understand your goal either. If an object has been rotated in 3D several times then the World Rotate Transform might look like this:

If you wanted to reorient the object so that is was aligned to the world you could not just type in 0 for x, y, z as the angles are cumulative. You could use the align tool though. Or, you could change the first three vectors of its transformation matrix to unit vectors in x, y, and z (i.e., [1,0,0] [0,1,0][0,0,1]) the 4th vector of the matrix is the position of the object. By definition this is 0,0,0 in local coordinates.

If the object has been scaled you could rescale it to 1 by normalizing the first 3 vectors. For example:

@leeminardi Thanks, could you just explain, how to use that "matrix" for someone who's not experienced in 3dsMax? 😉

Is this a script command which would work with copy and paste into the maxscript?

Is it possible to apply that to multiple objects?

What exactly would I have to write into maxscript (because I wonder that I see in the first line very special values, that confuse me)

Many thanks.

The following MaxScript will scale selected object to 1 and reorient them to world coordinates. It will not change their position.

-- scales selected object to 1 and orients them to world coordinate -- lrm 5/15/2020 objs = getcurrentselection() for i in objs do ( i.transform = (matrix3 [1,0,0][ 0,1,0][0,0,1] i.pos ) )

@leeminardi that's great.

is there also a chance to get the position reset, too? 🙂

then it would be like the "reset transformations", we are using in Maya. thanks!

(I tried to figure it out myself with editing your lines, but it's too far from what I'm used in MEL)

What should the position be reset to?

Absolute world set on 0 0 0 , this would be great

Just change the line:

i.transform = (matrix3 [1,0,0][ 0,1,0][0,0,1] i.pos )

i.transform = (matrix3 [1,0,0][ 0,1,0][0,0,1][0,0,0])
