Hi Michael,

Maybe I don't grasp the instance-block concept right but it could be that any instance, (not only the master) could be edited and the change would reflect on all others.

It would be a simple way of managing, and there could be the option of external-file instance thing capability...this way you could easily keep track of a master if you want to.

Just an idea!

That's one possibility... But also often an instance mechanism allows for things to be positioned independently from the master version.

Like for instance scaling an instance in many systems will only scale that instance and not have a ripple effect of also scaling all the other instances as well.

That allows for something like having a "snowflake" master object, and then a whole snowstorm of snowflake instances, each of which has a different position, orientation, and scale.


> and there could be the option of external-file instance thing capability...

Yup, of course each of these options that gets added adds a lot of work, especially with all the new UI that is involved for them.

For example an external-file capability would need more than just a checkbox on the Copy command to control it...

Hi Michael,

Maybe you could allow only uniform scaling and rotation on instances, the changes made anywhere this way would be the same, except for the rotation and scale factor.

For external instances it could work by dragging a file, another button in the 'drag and drop' window would invite you to choose the instance option.

Just some exploratory thoughts, I realize how things can get pretty complex!

Hi Marcus, those are definitely some good ideas!

That could possibly be a good way as an alternative shortcut to help set it up.

But I don't think it would work as the _only_ way to set up a file linkage, I mean what if you wanted to see what the linkages were in a file that you opened up from someone else?

What if you wanted to change the linkage to a different file name or remove it?

To fully support these kinds of tasks it really needs some kind of managment mechanism with its own dialogs, etc...


Taken all together, it is quite a large amount of work... I'm not really at a good place yet to dig into it yet.

But it is great to hear different ideas! I just wanted to explain that it may be a while yet before I am able to act on any of those.

I guess maybe we'll have to see how you are implimenting the v2 management system before we can make suggestions on how to encorporate instances. I've got a few ideas but it really depends on how the layers and colours system is going to work. Any more sneak peaks into your plans for this michael?

Hi Rob, well it is still kind of a work in progress.

There is some info on the direction and general ideas in these previous posts:
