I’m not sure if you adressed me, but I’ll answer anyway^^
I’ll give two suggestions, one small and one big.
Small:
Say you want to test different sets of colours for a model, e.g. Yellow Bike with red tires and blue seat vs green bike with red tires and yellow seat. As of now, we need to duplicate the model and add colours to both bikes. I would be A lot better if we could have tags, much like in Mac OS. Each tag would then represent a set of colours.
I could then go to “tags–> create new tag named yellow bike” and “tags–> create new tag named green bike”. Now I could add whatever colours to my model in my current “tag” or working space. I could then just click the other tag and add different sets of colours.
Large one:
This solution would be IMMENSE for me and I’m sure for many other peoples. This is something that is related not only to colours but also the file system.
Example: In Mac OS you have folders and subfolders and so on. Imagine trying to organise a set of courses in University say. You would have folders such as, head folder: School, subfolder: subject, subsubfolder : stuff related to each course… and so on. Now, in each subject we might have a Digital book for each course. What if we want to scroll between all those books? We would have to go through each folder and find the book. In Mac OS you can add tags, so you basically click on a folder or file and add a tag. We could create a tag named “Books” which when selected would display all books…
A system much like this would be Huge for Shapr3d (I think). This way we wouldn’t be stuck using folder and subfolders to organise and amend stuff quickly, but have a much more dynamic setup. We could have a tag for specific items. Whilst the directories could be the same, tags would greatly increase the speed of selecting different sets of objects. If we built a tower, we could sort them by layers, specific materials, objects we might be uncertain about and so on.
Being able to combine these two would be the best, although I’m not quite sure how that would work out. Please tell me if my explanation is bad and I’ll provide a better one in combination with pictures.
