Pas la peine c'est sur son carnet de doléances :)

<<I'm not really sure yet when MoI will have instances and blocks and particularly xrefs are probably even further out than a basic instance mechanism.

MoI is much more focused on being a drawing-ish tool, and just in general those features are somewhat more oriented towards assembling some large repeated pattern or assembly. It's a bit different kind of a thing than "drawing a shape".

If your current project needs such a large repetition in it, you probably are best off using some other program like Rhino to do that particular project instead of trying to do that one in MoI.

Eventually I do expect to have an instancing mechanism but I don't want to rush into it and end up forever locked into a possibly kind of antiquated system. So it's going to require quite a bit of planning to get it done, and things that require a lot of planning and design work are difficult to know when I will be able to get them done
