Let me try to explain the relationship between scenes and sections. This is a bit confusing when you first approach to this.
Trimble probably can explain this better than me:
Scenes: Creating Scenes | SketchUp Help
Sections: Slicing a Model to Peer Inside | SketchUp Help
But, here it goes.
Your model’s “styles” will stick to the each scene you add or update. And this “styles” may contain two information regarding sections:
- Enable/Disable “Section Planes”
- Enable/Disable “Section Cuts”
This is a global adjustment. Which means this setting will apply to all of your scenes using that specific “styles”
Also, each scene tracks information which section cut you have activated. (this is independent to styles)
If you have deactivated all sections shown in the scene, and disabled(styles) “Sections Cuts”, no section information will show in your scene.
If you have disabled(styles) “Section Cuts” and enabled(styles) “Section Planes”, then even if you have one section active, it will not cut.
Also, you cannot have two sections activated unless you place one section plane inside of the group. (scenes do not track information inside of groups)
I hope this makes sense.
