Linked blocks with Reference style layers: Layers always On when opening file

Serengeti (Rhino WIP)
1

As per the subject, I have a file which uses Linked blocks with Reference style layers.
If I have the layers switched off when closing and saving the file, I would assume those layers should be off when re-opening the file (just like normal layer behaviour). But they don’t. They always turn back on.

Interestingly enough the objects will remember their show/hide state on re-open. It would be great if they would also remember their layer visibility state.

Thanks,

Hi Andrew - I believe the layer behavior is expected as the linked file is re-read - its layer state has not been altered. The instances that are showing or hidden is presumably being kept track of by the parent file - these instances are objects in that file. I get that this is not necessarily the ideal layer behavior, but I think it is the expected behavior in the current state of things.

Hi Pascal,

I agree that the sub-layers within the Ref layer should respect the on-off state of the referenced file, but the layer of the referenced file (eg: RefFile.3dm) should remember it’s state when the file was closed. Currently it’s essentially resetting itself to on every time you open a file.

Personally, I use Linked- Referenced blocks for files that I don’t use often, but refer to occasionally. They are often huge files that I don’t want choking my working file. So to have to turn these ref layers off every time I open my working file isn’t helpful.

Hi Andrew - ah, OK, so it is the top level layer that is turning on every time, is that it? Does LayerStateManager help for now?

Hi Pascal,

Yes that will work.
ATM all my ref layers fall to the bottom of the layer list so I highlight them all and turn them all off!
