Dressing your windows — curtains, blinds, shades, and valances
A room isn't finished until the windows are dressed. RoomSketch3D's Window Treatments category — curtains, drapes, blinds, shades, and valances — attaches to any window, door, or opening, sizes itself to fit, layers up, and renders in 2D and 3D.
Bare windows make a 3D room look unfinished. RoomSketch3D includes a full Window Treatments category — soft options like curtain panels, curtain pairs, floor-length drapes, and valances, and hard options like roller shades, Roman blinds, Venetian blinds, and vertical blinds.
A treatment isn't free furniture you drop anywhere — it attaches to an opening. Pick a style from the catalog, then tap an existing window, door, or opening and the treatment snaps onto it and sizes itself to fit. So the one thing you need first is a window (or door, or opening) to dress.
What you'll need
- •A window, door, or opening to dress (add one first if your room has none)
- •A couple of minutes
Step by step
- 1
Make sure there's a window to dress
Treatments attach to an opening, so the wall needs one. If your room has no window yet, add a Window (or a door, or an Opening) from the Build panel first — treatments work on windows, sliding windows, openings, and every door type. Already have windows? Skip ahead.

Pick a window treatment
In the furniture catalog (the right-hand panel on a computer, Furnish on a phone — or its expand button, Open full catalog, for a bigger grid), search window treatment, curtains, blinds, shade, drapes, or valance. They're all in the Window Treatments category, in eight styles: Curtain Panel, Curtains (Pair), Floor-Length Drapes, Roller Shade, Roman Blind, Vertical Blinds, Venetian Blinds, and a Valance (a short topper). Pick the one you want — in the side panel, tap the tile and then its +Add button; in the full catalog, one tap does it.
Search "window treatment" (or "curtains", "blinds") and pick one of the eight styles. - 3
Tap the window to hang it
The plan prompts "Tap a window, door, or opening to add the treatment." Tap the opening you want to dress and the treatment attaches to it, auto-sized to that opening — no dragging or measuring. Curtains, drapes, and valances come out a little wider than the opening so they overhang the frame; blinds and shades fit the opening. The window stays selected, and its inspector lists the new treatment under Treatments with its Width and Drop already filled in. Tapping a blank wall does nothing (there's nothing to dress there), so aim for the window itself.
Tap the window — the drapes attach and size themselves (here 60" wide over a 48" window, 86" drop). - 4
Layer treatments for a finished look
You can stack more than one treatment on the same window. They sort by depth automatically — blinds and shades sit against the glass, curtains and drapes hang in front, and a valance is the frontmost topper — so a blind under drapes under a valance reads correctly in 2D and 3D. Tap the same window again with the next style selected — or, with the window selected, pick a style next to Treatments in its inspector and tap Add treatment.

Recolor and resize to your window
Select the window to open its inspector. Under Treatments, each layer on that window has its own row: a style dropdown (switch drapes to a Roman blind without re-adding), Width and Drop to fit your real window, and a Fabric color swatch — cool greys for blinds, warm neutrals or a bold fabric for curtains. Each style starts in a sensible default fabric tone so stacked layers stay tellable apart. To take a treatment off, tap the red minus button at the end of its row (Remove this window treatment).

See it in 3D
Switch to the 3D view and the treatment renders over the window — fabric folds on curtains and drapes, slats on blinds, a smooth pull on shades — so you can judge the dressed window in the room before you buy anything.
In 3D the treatment hangs over its window — compare the dressed window with the bare one beside it.
Tips
Add the windows first
Because treatments attach to openings, the fastest workflow is to place all your windows and doors, then go around dressing them. Trying to add a curtain to a wall with no window just does nothing — there's no opening to attach it to.
Layer a blind under drapes under a valance
Real windows are often dressed in layers. Attach a blind or shade for privacy, drapes in front for softness, and a valance across the top — RoomSketch3D orders them from the glass outward so they render in the right order without any fiddling.
Match treatments across a room
Windows on the same wall — or in the same open-plan space — look best in the same style and color. Dress one the way you want, then match the others so the room reads as one.
Common mistakes
Trying to drop a curtain on a bare wall
A treatment needs a window, door, or opening to attach to — tapping empty wall does nothing. If the treatment won't land, add a window there first, then tap the window.
Leaving windows bare in the 3D view
An undressed window is the quickest way to make a 3D room feel like a model instead of a home. Even a simple roller shade or curtain pair on the main windows makes the space read finished.
Frequently asked questions
What window treatments does RoomSketch3D have?
Eight, in the Window Treatments category: Curtain Panel, Curtains (Pair), Floor-Length Drapes, Roller Shade, Roman Blind, Vertical Blinds, Venetian Blinds, and a Valance. Search "curtains", "blinds", "shade", or "valance" to find them.
How do I put curtains on a window?
Pick the curtain style from the catalog, then tap the window on your plan. The plan prompts "Tap a window, door, or opening to add the treatment" — the curtains attach to that opening and size themselves to it automatically. You don't drag or measure them.
Do I need a window before I can add a treatment?
Yes — a treatment attaches to an opening. Add a window (or a door or opening) first, then dress it. Treatments work on windows, sliding windows, openings, and every door type; tapping a blank wall does nothing.
Can I put a blind and curtains on the same window?
Yes — treatments layer. Tap the same window with each style and RoomSketch3D orders them by depth: blinds and shades against the glass, curtains and drapes in front, and a valance as the frontmost topper — so the layers render correctly in 2D and 3D.
Can I change the color and size of a treatment?
Yes. Select the window to open its inspector — under Treatments, each layer has a style dropdown, Width, Drop, and a Fabric color swatch. To remove one, tap the red minus button at the end of its row (Remove this window treatment).
Do window treatments show in 3D?
Yes — every treatment renders over its window in the 3D view, with fabric folds on curtains and drapes, slats on Venetian and vertical blinds, and a smooth pull on roller and Roman shades.
