While we are talking about grouping of models, it would be great if you could select a group of models and associate them with a process rather than having to edit the process settings to select the models that it applies to. It catches me out every time when I duplicate a model because the process only applies to the original model and not the others that were added through duplication.
In my request just looking for familiar Mac/PC keyboard actions to select/add/remove items from a Group ... then MOVE, SCALE, ROTATE them.
SHIFT to ADD
SHIFT-CMD to REMOVE
CMD to SELECT
Or whatever is best and Standard in the computer interface world.
I'd like to second the request for being able to GROUP a set of imported models. Ideally, the software would then treat that group as a single unit and allow us to apply any commands to the group as a whole (rotate, move, apply process, etc). This would be in keeping with how many other design/layout programs work, and would be a huge boon to dual-extruder owners who want to print objects as a single piece.
