I certainly found it much easier to design on the model itself than create a component and try to get it oriented correctly. That was made a bit easier by figuring out the various pointer colours when clicking on various parts of the model to move it etc. The thing that really made it a bit easier was the discovery of the rotated rectangle feature as i have the model on a slightly dodgy axis, so that made creating square shapes a breeze relative to the rest of the model. the major downside that i found last night was that if you design on plan on a dodgy axis, flipping components has an odd effect on the piece
ScotlandtheDave wrote:Thanks also for the explanation on the bounding boxes, i didn't know why this happened, nor why all the textures were the same regardless of application. all good to know! Also, i'd been measuring all the faces of the components and naming them in the model, but it sounds like components will remove that effort.

ScotlandtheDave wrote:I was going to do a ground up redesign of this model, partly because i'd like to use Sketchup components properly and because the design is now a uniform rectangle so doesn't have to "fit" a particular space. I assume its a simple case of designing the components in the correcnt orientation them moving the complete model into its final position if need be? i.e. i could design the shed itself then place it within the ladscape, rather than try and design the shed on the landscape?
Thanks again for the feedback dave, Cheers

so you need to have a good handle on that. (Four candles. )
Dave R wrote:Layers are different in SketchUp compared to other programs that have them. In SketchUp, layers have one use and that is controlling the visibility of entities. There is Hide which you already found but that's not good for more than temporarily getting things out of the way.
There are a a few basic rules for layers in SketchUp. Follow them and you won't get hurt. Actually, if you follow them, you'll save yourself a lot of headaches and hair pulling.
Rule number one: Always leave Layer 0 active.
Rule number two: Always draw on Layer 0 and leave all edges and faces on that layer.
Rule number three: Only make layer associations for components/groups but leave all edges and faces within the component/group wrappers on Layer 0.
Rule number four: See rule number one.
Think about how you want to organize your model and make layers to suit. In this case you might make layers for the roof, landscape, walls, windows, doors, etc. If you want to show the shed with the roof off, you can turn off the roof layer. Or you might want to show the floor without the walls and windows.
Generally I draw the entire model first and create layers afterward. I get the model complete and then I create a scene showing the entire model. After that I create the layers and I turn their visibility off. then I assign components to layers. When I do, they clear the drawing space. When I have a blank screen I know I've assigned all of the components to layers. then just click the scene tab to make the model visible again. After that you can create scenes to show the model from different angles and with different layers turned on.
Alright. That's probably too much for now but I'll leave it. Have a good time with your shed.
Thanks for all the effort you put into your replies here Dave - makes me think.
The drawing has several downloaded models in it from the warehouse. many layers have come with those models. I have 30+ layers in the list. It doesn't seem to matter that a component has lots of layers marked as visible. The layer the component is on can still be turned off to hide it.
Seeing so many layers in the list all marked as visible confused me for a while. I'd need to name new layers to be easy to find alphabetically. layer0 is pinned at the top of the list but layer1 is half way down!
edit.. quick question... layer colours... I can change a layers colour but I don't see anything change colour. what are layer colours all about?
