3D models and smisioto (Step and WRL and wings) again

[maui]

@Walter_Lain

I know enough to say that, based on many years of working close to mechanic designers… hearing “WTF, this step is not opening right” or similars was quite common…

@maui

Mainly the issues on STEP interoperability are present because many vendors are used to defeaturing the models to avoid a full interchange of data.

you should ask your mechanical designer to ask his or her 3D model provider not to add any proprietary protection technique on the shared model…

I cannot see any user of KiCAD 3D library raise an issue on STEP model interoperability (not here nor at the GH repo)… and that is because the K library and the exporters (K or FC) are developed to allow and promote free interchange and not the opposite, as you can find in commercial environment…
And the exporting quality is depending on the quality of ALL of the contained 3D models…
This thread may add some tips:

Workaround: PCB STEP export into Solidworks

When I try to export a PCB from PCBnew into a STEP file and then subsequently import it into Solidworks I get all kinds of funky stuff. Sometimes majority of components show up with errors in the tree and are not showing up in the model itself. Sometimes all the the parts get replaced with a single random model (like resistors get replaced with a chip model or something to that effect). In short - it is messed up. I do have all the models for the components in step format. As a work around …
