Hi,
just to clarify: the 3d models of the official library must be created
such that the scaling factor in the footprint is set to 1. We are
currently rewording the whole section to be clearer

We can't remove the scaling option until we make the VRML importer
handle proper unit selection. I have routinely run into the case where
I go OpenSCAD -> Wings3D -> KiCad and design a model using mm in
OpenSCAD because it makes for easier computations (all the datasheet
values are nicely given in mm) and then have to apply a scaling factor
of 0.3937 to all the axes in KiCad to make it the proper size because
we seem to have a hardcoded assumption about what unit system the VRML
file is in.
In fact, the KLC says: WRL files do not specify absolute dimensions.
KiCad normalizes model parameters to units of inches and the internal
units (dimensionless) of the WRL model must be scaled accordingly.

There has been some discussion to removing the scale option here
altogether. The logic being that if you need the model scaled,
you should be doing this in your solid CAD not in your electronic
CAD. I have come around to this idea and it might be worth
implementing rather than doing the scale limiting.

Hi all,
I'm wondering if it is safe to limit the scale of shapes to be
positive values?
Applying negative scales will cause inverted shapes and render
issues on the models.
Could be that anyone in the world is using negative scale values?
or should be safe to limit it?
This is related with this issues:
