What do you think about such a feature:

I looks very nice on renderings. But i can't think of any use in the interactive view.

I've actually already done something similar to that .... almost.... with FreeCAD...I used Draft Polar Array. But of course that is actually making a parametric copy rather than just a visual display thing...

Juergen, in your Assembly information in the wiki, you talked about how Body and Assembly Part would work to allow screws and the like to be modelled once but displayed in multiple places...or something a little like that. So would Assembly be another way to achieve something similar but more efficient on processor time/memory etc. that Draft Array or Part Mirror?

Are you talking about doing a rendering or having that as part of the standard 3D view? If it's rendering, we can already do that. If your talking about having that feature in the standard 3D view, that would take a brand new 3D render engine. My first thought on that would be something like the quake render or some other 3D game engine, but all of those work from meshes and that would not be that compatible with FreeCAD I wouldn't think.

I know this is not the same, .. but just for the fun of it...

This uses Part WB Mirror, a Draft array would not give you a mirror image.

I don't think such migration is necessary. The feature should not be hard to implement.

The real question: Would it be useful? IMO some others things in the FreeCAD renderer are more urgent: performance optimisation, maybe level of detail (LOD) implementation...

[jriegel]

Its really not hard to implement, Coin3D is able to do it. But I'm also unsure if its needed....

If it's not that hard, make it option in Preferences > Display > 3D View. I had no idea that was available.

Is there a node which does it directly? Which one? But besides that I don't think we really need it in the 3d view because it disturbs more than it helps. But as Mark said it's possible with the Raytracing workbench and this is sufficient IMO.

[jriegel]

Its basically the transformation node where you transform (mirror) and render the same model again, plus a partially transparent "tabel" underneath the part. Thats all

But its probably really pretty useless....
