How to copy extrude/bevel data across multiple curve objects? I have imported 100 SVG objects (curves), these objects all need to have the exact extrude and bevel amounts. 

I am not able to use CNTRL + L to link object data or text data without changing the actual object. 

Does anyone know a quicker way to do this to all my objects? 

Perhaps a python script (or any other way that is quicker than manually doing this)?
I want to thank @Carlo for this handy tip.

This can be used in many different areas of Blender (I will post more scenarios when I have time). 


Shift Select all the objects you want to change.
With the last object selected make sure you hold down ALT and change the properties. This should affect all the objects you had selected.
