Is Rhino storing the object transformation

Hi,

Is Rhino storing the transformations of an object?

For example, if I create a sphere in 0,0,0 and 5mm radius, and I modify it using the gumball, is there a way to know that it was a sphere of 5mm?

Thanks,

You basically ask two questions. Rhino doesn’t store object transformations. But moving a sphere of radius 5 will not alter the fact that it is a sphere of radius 5

Hi,
Thanks for your answer!

Sorry, probably move was a bad example, I was thinking in scale and rotate too. :slight_smile:

Thanks,

Again the answer is no, Rhino doesn’t store deformations.

With the exception of block instances.

Can you explain this one a bit more? Where can I find the translation, rotation, and deformation of a block instance?

InstanceObject.InstanceXForm gives you all the transformation information.
