If so, we need to say that in the UI.  Right now if you add two models,

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.
