Change group layer without changing layers of objects within the group

Rhino Rhino for Windows

I have a lot groups, each group has a lot of objects that belong to different layers. Now I need to turn some of these groups on/off, I guess assign these groups to another layer would be one way, but the problem is when I change the layer for these groups, all the objects’ layer will also be changed into that target layer. Is there anyway to work this out? Any alternative solutions?

Hi -

Groups don’t have a layer.

You can select a group and hide or show just that.
Note that you can also name groups by using the -group command (i.e. the dashed version) and use SelGroup to select a specific group from a list.

I cannot understand why a group contains different layers keeps the original layers in the group.
But as soon as the group is set to a layer called “my layer” let’s says all layers in the group are set to “my layer”

Should not be.
The only way to achieve this is to make a block and not a group.

Can’t groups keep the original layers of the objects in the group, and be set in to a layer WITHOUT changing the layers in the group ?
An option for this ?

Would be great, for layer management.

An answer ?

Best regards

Hi Karim - a group is not a ‘thing’ like a block instance, it is really just a selection set.

Hi Pascal

I understand
But it could be much more than that
If it kept original layers in the group when set to another layer, I could use generic layer names like “window” “door” “slab”, then move the group to a floor “1st floor”, “2dn floor”
BUT without having to duplicate the layer names in each “1st floor”, “2dn floor” sublayer…

I tried that, was fast and efficient.

Only way is to make blocks
Or duplicate all layers in each parent floor layer

Any other way ?

Many thanks

Hi Karim - can you post a simple example file with the starting state and one with the desired ending state?

Ok my generic layer names are sub-layers of “—” layer
My floor layers are
0e
1e
2e
3e
-1e
9e

The starting states are layers
1e
2e
3e
-1e
9e
They contain groups that no longer kept their original layers…

My desired ending state is layer 0e
It contains only blocks (I used GroupToblock)

…

I’d Love you to find a solution without having to make blocks…
