To be fair, as it stands now, even if it is "only" for the pin headers,
this is close to half of the 3d library size as of now.
The pin headers can now be of an arbitrary size as well. Someone can now
create a 4x6 pin header for example, and the current footprints can be
converted to this array system, thus reducing the size.
Arbitrary pin headers are a step up anyway.
This being said, I have not tested the patch yet, but even if it is "only"
for pin headers, the idea is sound to me.

Hi Oliver,
I'm sorry not to be on your side for this option...
1) for which kind of modules this array is applicable?
I see only pin-headers straight and angled...
for example box headers are not easily done unless you consider to manage
by the code the box for each model
2) the problem related to the big 3D library dimension will not be
covered unless for some little family that can be managed by this on the fly
generator
As I already suggested, the issue with the huge 3D github library can be
managed in a different way:
1) give the kicad users only a basic 3D library (i.e. most used smd and
th families)
2) give an option to pcbnew to automatically create a list of the missing
models needed for a project and collecting only them through a wget
process...
This will give a very low downloading band need and will not increase the
need of disk space for having all the 3D library locally, full of unwanted
models.
Here a conversation of this issue:

To provide an option to reduce the size of the 3D model library, I have
implemented an "array" feature for 3D models. A module (footprint) can
reference a single model multiple times, with a dimensional offset between
each copy.
(Note - just the PinHeader models are currently over 1GB! This feature
lets you use a single 3D model for all pin headers or similar repetitive
footprints within a certain series).
Features:
1. Specify repeat count and repeat step in x/y/z axes
2. Save / load implemented. (If no repeat option used, no extra output
is generated - old files are not touched)
3. Render in 3D viewer
4. Render in raytracing viewer
5. Export to VRML (multiple references to single file)
6. Export to STEP
Notes:
a. An exported STEP file will now be (possibly) much smaller as it
references a single small object multiple times
b. There were a couple of bugs I found where model offset units were
incorrectly translated between INCHES and MM
A couple of screenshots:

Testing:
Wayne verified that the file units for 3D model data are in mm - I
*think* this means that there was previously a bug regarding 3D model
offset, where the scaling factor in the file was interpreted as inches when
exporting (e.g. to STEP)
I believe I have fixed this bug - confirmation would be great.
Cheers,
Oliver
