[Mário Luzeiro <mrluzeiro@xxxxx>]

Hi Maurice,

In any case, Cirilo is looking for a solution for KiCad. No matter if we like it or not. That are separated things.
Even if the quality is good or bad, he have to compare with something and one thing would be a (good or bad) 3d plugin for (integration with) kicad other will be a 3rd part tool (good or bad).

So even if FreeCAD was perfect, it was not a KiCad software part.

If you want watch a movie, you can go to the cinema or watch it at home (if you have a home cinema player or something to play it).
At moment it is still not possible to watch a movie at home with KiCad... if that becomes possible, people are still free to go to the cinema.. because that are two different ways of watch a movie.

Probably Cirilo got the wrong movie room or it was not an IMAX cinema... but in any case.. I think he is looking for an "home theater cinema" solution.

Do not miss the scenes of the next episode... :) .. aaand back to work..

MRL

you don't see anything against FreeCAD quality here?

> Thanks for pointing out the problem with FreeCAD bloating the STEP files. For me that means that I'll have to go create a lightweight STEP library for kicad some time in the future. I already have an IGES library which is capable of creating PCB mechanical assembly models but (a) I need to make some large changes to kicad so that Export functions can be implemented by plugins and (b) my library has no provisions to actually display a model. Since I only work on the code in what little spare time I have, it will be a year or more before we see any such features in kicad. At least for now there's FreeCAD, even if it bloats the models by a ridiculous amount.

and I'm giving just technical help on what I consider not correct
information on FreeCAD comparison to help people not following wrong
advices...

that would nice, but I suspect that he won't reply this mailing list
anymore ...
