Deleting layers
-
A couple of questions about layers and geometry I'm hoping the sages here can help me out with
I really try hard to keep my models "clean": all primitive geometry on Layer 0 and an extensive layering system for components and groups. I've noticed recently something that seems odd - I'll create some geometry, select all of it, group / component-ize, then move it to some layer that makes sense to me. If I then explode that object, all of the primitives (lines and faces) have now moved to that layer that I moved the grouped geometry to. I thought that the primitives that make up a group were supposed to all remain on "Layer 0".
And this may factor into this next, more pertinent, question
Sometimes I use temporary layers to work with groups / components that I'll then include with others of similar nature on a separate, permanent layer. I then go to delete that temporary layer, attempting to keep the model and organization clean. Often as not, I get a dialog about the layer I'm trying to delete not being empty. I will turn off all layers except for that particular layer and there are no objects to be seen. Or selected. So now, I want to delete a layer but, I suspect, has primitives on it that are part of a group that is hidden by virtue of being on a layer that is turned off. How can I find this geometry on the layer I want to delete, short of going through a whole bunch of layers and exploding groups, moving to Layer 0, regrouping, moving to the layer I want it on... etc
Clearly, there is something I misunderstand...
Thanks in advance

That is a weird thing about layers when you explode groups or component. It can be leveraged when you're using nested components/groups but with raw geometry it's a bugger. TIG's plugin can help but one thing I've found useful is after exploding a bottom level group, all of its geometry will be highlighted. Immediately correct the layer association in Entity Info and you won't have a problem.
To be honest, I rarely if ever have a need to explode a component after I've created it so this is rarely an issue for me, anyway.

Tig created a plugin to help with the issue of primitives exploding onto other layers.

Thanks, Box. I tried the plugin but it seemed to conflict with my 3Skeng plug in, so I uninstalled it.

Hi Dave
Yea, I try to avoid exploding groups and components as much as possible, but I have a devil of a time keeping complex groups "solid" as I manipulate them. Irregular shapes and all that I use to cut one group against another. Been burning my brain lately...
Thanks. Maybe you can help out with my next post!
