Is there no way to delete a layer directly?

Not via the API, erase! method for layers and materials are missing. There's also missing methods to edit names etc...

I don't understand the statement above ^^^

Did you alter this thread in some way?

[Edit: Ah I see - you added a post to the thread so you could follow it easier. It might be better to just add a nice comment - like - "Thank you all, this is usefull information", or you could subscribe to the thread instead.}

No, but now he can find it by looking at his profile and listing all his posts. And so can I.....but I'm not really involved with layers at this point. Good luck!

Hi TIG,
I was just considering the same feature for the new release of my Layer Manager. I thought it could work (from the user point of view) just like AutoCad did (some versions ago), so it asks wether you want to:

delete the entire content of the layer before deleting the layer,

move the entities to default or another layer.
it would have to scan for groups containing objects on the layer to delete, and for compos definitions too.
Before developping it, do you think this feature will be useful for users, assuming that there will be other tools in the Layer Manager to easily move entities from one layer to another ?
Thanks in advance,

Didier
Please feel free to use my ideas in your upgraded Layer Manager... I think it could be useful...
As presently configured my code moves any entities on layer_to_go to the default layer [ each...e.layer=nil] BUT instead you could move them to another designated layer [ each...e.layer=another_layer] OR simply delete them [ each...e.erase!] instead, in your suggested additional options... My code already makes 'nil' every entity on layer_to_go in the model AND inside every definition [which includes groups], before removing the layer, using the same method you could change the entity's layer or erase it...
Note that to ensure the layer goes from the browser you need your code to be inside a start...commit.

Thanks TIG, yur programming is more compact and clever than mine was on this one !

Yes sorry Al et al (both for being lazy and somewhat terse) but as you can see I am addicted to putting lots of things in one easily accessible place/machine:

Another proposed turn of the interface indicates why I have a big interest in deleting layers containing components rather than dimensions and labels:

and of course a big thank you to TIG and the others contributing to this topic.

ThomThom,

You can edit a layer name with layer.name=
Although you will only see the changed layername when reopening the layer window.
(I don't know however what is done with SU entities on that layer, since i only rename empty layers in my script)

TIG

Using layer.name="xxx" simply changes that layer name to "xxx" - entities etc aren't affected as they refer to the layer by its id not its name.
A simple way to change a layer IF it exists is something like

model=Sketchup.active_model
model.layers["ABC"].name="XYZ" if model.layers["ABC"]

Great thx Tig for the extra explanation

Now if only this was possible for materials to (without having to duplicate the entities first)

BTW Tig, do you know if is possible to refresh the Layer window?
