Multiple 3d shapes is actually great.
I use it when i have a component that is a second PCB that can be mounted
in two different orientations.

This is the primary purpose of this feature.

A TO3 package with its heat-sink needs six 3D shapes (for guys who really 
*like* realistic 3D views
of course...):
the TO3 package.
its heat-sink.
2 nuts.
2 bolts.

and to do that, adjusting X,Y and Z offsets is necessary.

I use this feature for components that may have multiple bodies, like a
battery inside a battery holder, or the mating board into a connector. It
is great for making rudimentary assemblies as kicad cant place any bodies
that are not associated with a component.

Re: [Kicad-developers] What is the purpose of multiple 3D models?

2018-03-31 Thread Pedro Martin 

Jeff, do you mean transistor+heatsink or .wrl & .step?

For transistor+heatsink I just add both models to the 3D shape names list.

For .wrl and .step the models must be checked individually, because if 
both models are in the list, they get overlapped and I don't know which 
one is being selected. In fact, I believe both are selected and I see 
"only one" because they are identical.

I got my models with the freecad kicad-stepup export tool.

Regards,
Pedro.

Sometimes you would like to add myltiple models to a footprint.

There is a subtle but important feature. It will render a wrl model
over a step file, because users with wrl models use them for more
control over surface properties, but will still be able to export a
step assembly if the model exists with the same name as the wrl, but
just with the stp extension. See Maurices freecad script tool.

On that, I don't really think we need to do much in the GUI other that
what is done now.

One feature that is a bit wonky is the preview when browsing for a
model. It is not a standard opem file dialog because it was not
possible to add the preview pane in wx on all platforms to the native
file selector. It was decided to have the one we have now for cross
platform consistency.


   Thanks,
   Jeff.
