Since the macnets are permanently attached to the box, is this version really useful???

I agree with philo here that having this special shortcut
without magnets makes no sense IMHO.
It would be fully sufficient to just have 1 shortcut,
the one with the magnets.

No, because then if you want to assemble a train on a curved track - which I have done - you are forced to construct the entire battery-tender from the various parts: the body, the base, two axles, four wheels, the cutout-button and the direction-lever. This part makes perfect sense.

... or make two more shortcuts _with_ magnets
- one with both magnets angled for a curve
- one with only one magnet angled for a curve the other straight

No, cos the angle of the magnet on the tender depends on the distance between the axle and the magnet of the wagon the tender is connected to.

The usecase you describe is also one that I have in mind for the train parts. I also want to animate them, also in curves.
However, having this file is not a necessary precondition to do that.
For all our other LEGO parts, we don't create assemblies especially crafted for animation. If you are using some shortcut (be it e.g. a Dragon figure, or a minifig on a bike, or a Fabuland character moving its body), then your standard usecase is that you have to animate portions of the existing official LDRAW files. You anyway have to "disassemble" them to animate them. So nothing special is about this very part here. Animating it can happen as for all other parts: by "disassembling" the official LDRAW files and shortcuts.

The parts you describe all have movable joints - arms, legs, etc. This one does not.

All the other train bases have with-magnets and without-magnets versions.

There is no drawback to having this file. If it really bothers you that much then just delete your copy of it :-P

there's a misunderstanding here.
you must not compare this file with my argumentation above.
you need to use the current ...c01 file.
and that _contains_ movable parts: the magnets.

I forgot to answer your second argument,
pointing out that other train base parts exist in
two versions "with" and "without" magnets.
That is, because they are parts. You need to have a file with just the train base. And then you have an assembly adding the magnets.
That's perfectly fine. The situation here is analogous: you have separate part files for the battery wagon body case, for its bottom,
and an assembly (c01) for everything together plus magnets.
*this* file (c02) does not fit into that scheme.
It is a "partial" assembly, a subset of the c01 file.
Would we carry over your argumentation to our files collection as a whole, then we would need to create such "partial assembles for animation" for many other files as well, and this would clutter the library IMHO.

I would like to answer Chris' suggestion above,
having several shortcuts here with different magnet angles.
I dislike that, because, to do a smooth animation when this
part moves along a straight track segment and then into a curve,
you need a smooth angle transition. The assemblies you suggest
will not help much there. Everybody doing that will not profit
from such shortcuts, which will as well just clutter our releases IMHO.
Doing animation requires explicit disassembly of existing files
and dedicatedly moving certain parts, there's no way around it.

I additionally would like to add that we in the past at some time
came up with the idea of putting meta information into a *.dat file,
which could describe the movable parts. E.g., for the magnets we
could have information about their rotation point and which angles are possible. Currently, such information is kept in supplemental databases AFAIK. Together with connectivity meta information this could in a far future become a quite powerful concept.

1. I was not referring to the locomotive bases (eg x280.dat / x280c01.dat), but to the wagon bases (eg x270.dat / x270c01.dat / x270c02.dat) which follow this pattern and naming scheme.

2. "Clutter"? Seriously? I'm in favour of making it *easier* to build models, not harder.

3. If you're really going to suggest that this is a "special" case because c02 is a subset of c01 then I would like to point out that the Fabuland figures are no different: u9107p01c01.dat is a subset of u9107p01c02.dat.

4. Who said anything about animation? I've simply assembled a model of a train on a curved track.

Re: 1:
Okay, I understand. You are referring to 270 / x270c01 / x270c02
and 736 / 736c01 / 736c02. Of these, none of the ...c01/...c02
assemblies have been official. My arguments brought up here
apply as well there: I was argumenting against having the c01
combination. However, I overlooked your argument #4: building a model
of a train with correctly positioned magnets is very difficult without those c01 files. Somehow, I only got animation and not model building in my focus. Sorry for that. For model building, the c01 files are indeed useful. I retract my counterargument.

Re: 2:
I was just referring to the number of ...c0x *files*.

Re: 3:
You have not carried over my argumentation properly to the Fabuland parts. There, files exist for each physical part, plus assemblies of the figures. When animating, you have to disassemble the figure shortcuts. The situation here is different: additional to the parts plus 1 assembly, you have the c01 files mentioned in 1:.

Re: 4:
My fault, sorry. See Re: 1:


Summarizing the above: I retract my counterarguments against this shortcut, but am still holding for 2 reasons:

a) the type of this file is currently "part" but should be "shortcut"
b) the order of c01 vs. c02 is wrong here IMHO. They are reversed
compared to
270 / x270c01 / x270c02
736 / 736c01 / 736c02

When correcting b), don't forget
to reverse the analogous "black wheels" variant c11/c12 as well.
Their file names appear strange to me. Why not simply use c03 and c04 there?

1. The numbers were assigned by Chris IIRC, not me. I agree, though, that they make more sense the other way around.

3. But you don't have to dismantle the Fabuland figure's head assembly: it is not necessary to separate the head from the neck. As such, the head assembly is analogous to this assembly here: it's the parts which are permanently (or semi-permanently) assembled and not intended to move in relation to one another.

thread http://forums.ldraw.org/read.php?19,214,323#msg-323
has finally solved the metal color problem.
383 = lacquered plastic
494 = real metal
so 383 is wrong here, replace by 494

As this file only references to other parts I think this one is correct. The errors has to be fixed in the referenced files.
