Cross-Section & Interior Views —Read the Building
Some questions need the house cut open. Builder's view modes read the building instead of decorating it: an editorial cross-section slices the model with a clipping plane so both levels show at once, interior placement ghosts furniture while you position it, and layer toggles with a grid keep the plan legible. Underneath, interiors stay honest — every daylit opening carries a RectAreaLight into the room, and interior faces use a dimmed indoor ambient.
How it works — in the app
Read both floors
Walls, openings and structure in one cut — ground floor and attic together.
Place with ghosting
Turn on interior ghosting and position furniture without losing the walls.
Check the plan
Toggle layers and the grid — then toggle them off and look again.
What you get
Cross-section & interior views is one of fifteen feature pages covering what ships in Builder today — every claim here maps to a shipped, verified feature. The list below is the concrete surface:
- Editorial cross-section: a clipping plane that cuts the model for true section views
- Interior placement ghosting — furniture goes translucent while you position it
- Layer toggles and grid for plan legibility
- Interior daylight done right: a RectAreaLight through every daylit opening
- Dimmed indoor ambient on interior faces — rooms light correctly instead of glowing uniformly
- Screen-space reflections on glazing, so section glass reads as glass
FAQ
What is ghosting for?
Placing things inside rooms. With interior ghosting on, the furniture you are positioning turns translucent against the walls, so you can see the room while the object is under the cursor — place it, and it solidifies into the scene.
Can I see both floors at once?
Yes — that is the cross-section. The clipping plane cuts the model where you slide it, so the ground floor's walls and the attic's roof structure read in one view. It is a view mode: the design underneath is untouched.
Does the section view change my design?
No. Cross-section, ghosting, layers and grid are view modes — they read the building and change nothing. Hand them to a client and the design is exactly as you left it.
