OK. Now it’s time to address your use of layers. Here’s the Layers panel as it appears when I opened your latest (I’ve highlighted two columns, one in yellow, one in blue)
The yellow column controls which layer is associated with any new geometry you are drawing. And this shows an extremely common mistake: By drawing with the dot in a layer other than Layer0, you are associating new geometry with a layer that isn’t Layer0. By selecting other parts of your model, I see that you’ve also associated geometry with the “Garage” and “Basement” layers - and I stopped checking there.
Edges and Faces should always be associated with Layer0! Control their visibility by combining them in grouping (groups or components), then associate the grouping as a whole to a layer. As long as you keep the selected “dot” in the yellow highlighted column above on “Layer0”, your raw geometry (edges and faces) will remain associated with Layer0.
Additionally, you still don’t have a lot of your geometry correctly grouped. Yes, you’ve associated raw geometry to named layers (a mistake), but layers are for visibility control ONLY - they don’t accomplish geometry isolation!
Now this may seem counterintuitive, but the way to “fix” your mistaken layer associations for raw geometry is to delete all your layers except Layer0 as follows:
- Put the dot in the yellow column in the Layers tool back on “Layer0”
- Highlight all the other layers by clicking on the word “Basement”, then while holding down the “shift” key, click on the word “lot”
- Click on the “minus” sign up top. Wait - this might be easier to show in a .gif:
Now, all your raw geometry will be associated with Layer0. You can now create layers for visibility only, group your geometry into various groups, then associate each group with the appropriate visibility layer.
Even with as small a model as yours, however, the creation of distinct groups will likely frustrate you as many of your parts that you might want to group are already merged to other parts. Even here, it’s probably better to start from scratch with the following workflow and only 1 layer: Layer0:
- Create a 3d “part” - like a slab, or the rain tank, or a set of walls.
- Select all raw geometry in the “part” you just drew, right click, and select either “Make Group” or “Make Component” - I prefer to use components as you can name them individually (and for other reasons that aren’t applicable here)
Repeat the above for each “part”. Notice I’ve said NOTHING about other layers yet!
Once you have all your parts created - and their geometry properly isolated in groupings, go to the layers tool and add layers you want to use - remember these are for visibility only!
Finally, one at a time, with the Entity tool open, select a “part” with a single click (a double click will “open” the part for editing), then using the pulldown for “layer” in the Entity panel, associate the part with the appropriate layer. Repeat for each part.
