I am incrementally becoming more confused about the issue of catalog dimensions.

I know that bricks are supposed to be stored as studs. and set/books/gear are
stored as cm.

When I look at the catalog page for
 
Part No: 3003  Name: Brick 2 x 2
* 
3003 Brick 2 x 2
Parts: Brick
I see 'Size: 2 x 2 x 1 in studs'

When I look at the catalog page for
 
Part No: 3437  Name: Duplo, Brick 2 x 2
* 
3437 Duplo, Brick 2 x 2
Parts: DUPLO, Brick
I see 'Size: 2 x 2 x 1 in studs'

When I look at the dimensions in a catalog XML file I see (for both) …
ITEMDIMX 2 /ITEMDIMX
ITEMDIMY 2 /ITEMDIMY
ITEMDIMZ 1 /ITEMDIMZ

When I look at the values beneath an actual listed lot (3003) I see: 16mm 11.2mm
16mm

When I look at the values beneath an actual listed lot (3437) I see: 32mm 23.6mm
32mm

So that suggests that the XML download file does not actually represent the values
being used by IC … or does it? I don't mind the values I'm receiving,
but I would like access to the real numbers as well.

Remember that LEGO bricks are measured in lego studs, whereas Duplo bricks are
measured in duplo studs. So while both are 2x2x1 in studs, they are measured
in different stud units.

The metric measurements make sense, as the duplo piece is 2x bigger in all dimensions
than the LEGO brick.

There are two other big problems:

1. The dimensions aren’t given in “studs,” there are given in “studs x studs
x brick-height.”

2. Dimensions in studs are “width x depth x height,” others are “width x height
x depth” (Y is often up in 3D software).

I know that, you know that, but the catalog pages (for either of them) represent
all three as studs.

My point exactly: WE know that but the website (catalogue, IC info…) is obscure,
confusing, and inconsistent.

Yet some of us are working every day to make it less so. There's still plenty
of work to be done if you'd like to help.

Your (personal and group) work on the inventories is highly appreciated. You
can verify I have already contributed several times when I could but for me to
contribute more, you’ll have to send me free sets to inventory.

Anyway, we, users, don’t have any way to change “2 x 2 x 1 in studs” to “2 studs
x 2 studs x 1 brick.”

I am ok with the above if it were labeled as 'Logical Dimensions'. What
appears to missing here is the 'Physical Dimensions', i.e. the specific
numbers in metric measurement. Before you tell me how easy it is to convert,
it's not. The above examples illustrate the problem.

Something must be lost in translation:

You: There are inconsistencies and confusion.
  Yorbrick: System studs and Duplo studs differ.
    Me: There are other problems too.
      You: No, the catalogue is confusing!
        Me: Yes, I just said that.
          StormChaser: Just contribute!
            Me: We can’t change the website.
              You: That solution won’t do!


It wasn’t a proposition for a solution. It was an example of what users can’t
do.
If users can’t change a wording, how could they add information?

All you say is correct and makes sense. But IC does not use studs, it (apparently)
is using mm, and those values are being obscured from view. Why ?

OK I see what you mean, yes I guess it would be useful to show it on the catalogue
page too.
