Scale/Dimension change when I add a curve modifier First, I have created both a plane and a curve object, then I adjusted their dimensions as desired. Noticing that the scales of both changed with the dimensions, I press CtrlA after the re-dimensioning of each of the objects, with that object being selected alone.

Till here, everything is fine, both objects have now the desired dimensions with a scale of one.

The issue is: When I add a curve modifier to the plane and choose the curve previously created in that modifier, the plane dimensions change for some reason! :s

Any idea why?!

EDIT:

Link to an example blend file:



Go to the modifier tab of the plane object and select the curve called Circle to see how the dimensions of the plane change!
Solution Found!! :D

Modifying the dimensions of the objects in EDIT mode solves the issue. It seems that my previous method of modifying dimensions in OBJECT mode does not actually modify the dimensions but applies a transform to the objects. And when the plane gets associated to the curve via the modifier, it seems that the transform of the curve gets also applied to the plane, which results in the weird change in dimensions I was observing.

Anyway, problem solved... Thanks to all those who tried to help!
