%%%Apply Scale in curves don't work as is supposed to.

- Operating System, Graphics card ---

O.S.: Windows 7, 64-bit (SP1)
Processor: Intel Q9550, memory: 8GB DDR3
Graphic Card: Nvidia Geforce 550 Ti
Nvidia graphics driver version: 320.00

- Blender version with error, and version that worked ---

blender-2.67-r56608-win64 (downloaded from builder.blender.org)

- Short description of error ---

Applying Scale to a Curve object in Blender doesn't appear to work... In the linked Youtube video I explain the problem.

Just in case, I'm also attaching the video (Webm).%%%

%%%It scales the curve vertex radius, see the 3D view transform panel.%%%

%%%Isn't that even more weird?... IMHO, the vertex radius should stay in 1.0 when you Apply Scale.%%%

%%%It makes sense to me, apply scale affects the vertex locations so why not also the scale?

The rule for apply is that the curve still looks the same afterwards, moving the scaling from the object to the curve data. It can then either apply that scale to the vertices, or to the bevel depth. Maybe changing the bevel depth would be better, but that's a matter of preference.%%%

%%%I would not consider this is a bug. The thing here is -- when you're using bevel object and scale curve up, in most cases you'll want it's exact shape to be preserved. In that case you'll need to apply scale on radius as well.

Actually, this is also possible some of artists will want shape to be preserved when not using bevel object, but using extrusion instead. So this is two conflicting expectations here, which are both valid. But would rather not change behavior here, this is how things worked and everyone got used to it.

Thanks for the report anyway.

P.S. Please, do not use videos explaining the bug, in 99% of cases they're time consuming to watch. Use simple .blend file with few lines of comments if needed.%%%

%%%Ok, I didn't know if it was just an inconsistency or an actual bug :)...

@Sergey:
Normally I just describe the error/bug and attach a file (I've reported -confirmed- bugs before), but in this case I saw as a better option just to do a video. The video is 2' 51'' long... That takes less time than reading a bug description, download a file, open it and check/confirm this bug/inconsistency.

Anyway, thank you for your time :). %%%

%%%In investigating the bug I have to go back multiple times to the description to make really sure I'm doing the same thing and understanding the problem. A video is much slower for that because scrubbing through the video is slow, there's no easy way to jump to a particular step.%%%
