Maurice, I really like the idea of downloading models on an as-needed basis. This will be a lot of work to implement (but I think it could be done).
This patch is not intended to be the final solution for the libraries issue. I would still support a move to download models as needed On Tue, Nov 7, 2017 at 2:22 AM, easyw <[email protected]> wrote: > 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: > https://github.com/KiCad/kicad-library/issues/1532#issuecomment-341707706 > > my two-cents > Maurice > > > On 11/06/2017 3:01 PM, Oliver Walters wrote: > >> To provide an option to reduce the size of the 3D model library, I have >> implemented an "array" feature for 3D models.
