I have an exterior social area that includes a swimming pool that is somewhat indoor/outdoor. I had originally placed it Elements_Hard Surfaces but that layer doesn’t display in a Construction/Floor Plan. Would the proper layer be Element_Floors?
Correct, you could also place it on Element_Floors. Keep in mind that you can customize any viewport style then re-save as a custom set or change a scene by toggling on layers that you want to appear in your drawing. This also might be an option.
