![]() The loose geometry consists of the faces and edges of the table top. There’s no group or component for the table top or for the table as a whole. I’ll focus on the table – the table components right now are just the four table legs. The Outliner shows all groups and components in the model. ![]() There is some loose geometry – some faces and edges that are not included in any groups or components. But for purposes of demonstration, this kitchen set model consists almost entirely of groups and components. ![]() To illustrate the how’s and why’s, I’ll use this simple model of a kitchen set: Loose GeometryĪ perfect model consists entirely of groups and components – no loose geometry. Only move groups and components to different layers.Create all loose geometry (faces and edges) on Layer0, never anywhere else.Here’s the best practice rule for layers: And Part 3 will cover scenes, which give you control over which layers are displayed. In Part 2 you’ll see some case studies of highly detailed models that follow the same principles. In this post I’ll discuss the fundamentals of layer placement. When you model using groups and components (which all good modelers do), and start placing groups, components, or loose geometry onto different layers, things can get a little messy. ![]() What could go wrong?Īctually, quite a bit. Place a SketchUp object on a layer, turn off the layer, hide the object. Thank you again, Dave, for taking the time to help me.Layers – they seem simple enough. In my defense, I am still a beginner and am still learning the basic. I am sure the overall size of my model is so large because there is a small half-spheres used for each bead on the mouldings. Additionally, I put each piece of furniture on its own layer. That means that there are 3 layers (for the 3 different walls other than the bath area) for each crown design, each chair rail design, each base design, and each casing design. I don't recall doing it, and I thought I was being careful, but I shall just have to be more careful!Īs to why I am using so many layers, it is so I can try out each different moulding in its place on each wall, switching them back and forth to see the difference. Just to put a fork into this and call it done (and to help others who might read this), it seems I must have somehow deleted the objects in those layers and then they disappeared when I cleaned up last time. I know the models themselves would be more useful, but they are 8mb each and so exceed what I believe is a 2mg limit for attachments. The second is of the layer list from the older model that I abandoned that still has the missing layers for comparison. The first is of the layer list from the model I am currently working on. Is there a limit? I did a search and the only thing I found was a reply that said you could have 500 layers, and I am no where close to that. These missing layers were all at the bottom of the list. Shower Glass, Shower Wall Back, Shower Wall Closet Side, Shower Wall Long Side, Tub, Tub Base, and possibly others are all gone. Only the layers labeled Shower Crown, Shower Under Crown, and Tub Corners remain. In the model I am working on, there was an entire section for the shower walls, the tub, and the moulding at the base of the tub. It isn't that when I select a layer to turn on that it isn't showing up in the model, what I mean is that the layer is no longer even showing up in the list of layers! I was just beginning to feel very confident when working with layers (even thought to name in such a way to make them easy to find), but all of a sudden, some are missing. Each wall of the bathroom, and each moulding trial on each wall is on its own layer. I am fussing about with the moulding in a bathroom. If it shows up twice, I would like to ask the moderators to kindly remove the other one.) I sent it once and it didn't show up, so I've sent it again. (I'm sorry if this eventually shows up twice.
