I'm running into some strange issues with Components and Layers.
I have a very large and old model of my home. It's a complete model of my home down to the millwork and light fixtures. Luckily, I live in a 1981 tract home so the millwork isn't complicated.
Anyway, I've been working on this thing continuously for about three years now. My skills at Sketchup have been improving the entire time and I think that's part of the problem. There's been a couple occasions where I've done a major overhaul of sections because I discovered a new technique or it turns out the methods I was using were shortsighted.
Now I am running into a problem with Components that are split across layers. For instance, I have a component for a door frame. The individual parts of the component may be on "Layer 0" but the component itself may be assigned to "Main Floor". Additionally, I've somehow come up with some composite components (components which contain other components) that amplify the problem exponentially.... the interior components may have parts on different layers from other components of the same component, etc etc etc...
The main problem is with hiding layers. I have each room of the house as its own layer so I can hide areas I'm not working on. In a couple rooms, it seems like all the millwork is on "Layer 0" but the room structure is on the appropriate layer. I have to click on/off two or three (sometimes seemingly unrelated) layers to get the room, millwork, and built-ins to all appear correctly. Then I look at the components and they're on the right layer but the guts of them are not. It's frustrating.
I've also run into a ghosting issue. Sometimes I'll have a layer where one part is somehow shared between layers. This one I don't really get how I'm even doing it. But Sketchup begins to act strangely, not letting me add geometry or adding it but highlighting it blue. I'm obviously doing something wrong there.
Finally, all these reused and scattered components make the Object Browser really unwieldy. I don't use that tool much but it'd be nice if it were comprehensible.
I just don't know what to with all these re-used components. Is there a page or document somewhere that shows best practices for using components in a multi-layer environment?
