To build a room in Event Design App, open the Walls panel and either enter Length and Width under Quick Room for a rectangle, or click wall points for any outline. Then set each wall's height and thickness and apply colors and textures, giving you a walled venue shell with a floor to design inside.
Scope: this is for building the room yourself in the editor, in top view. If your venue came from an uploaded floor plan or background image, use the floor-plan articles instead.
If your venue isn't a blank canvas, you need walls before you can place anything sensibly: where guests enter, where the tables can go, what the room feels like. The Walls panel builds the shell (the room outline, or floor plan), then lets you edit and finish it.
📺 Create a Quick Room and Draw Walls Point by Point, Edit Wall Segments, Corners, Height, and Thickness and Style Walls and Auto Floors with Colors and Textures — three lessons: build, edit, finish.
Start in a practice plan in top view, and choose Wall in the toolbar to open the Walls panel.
[SCREENSHOT 1 — Walls panel: Create Wall buttons, Quick Room fields, Edit Wall, Floor Information]
The venue shell can be built in one of two ways.
Quick Room is for a rectangular room.
Under Quick Room (center), enter Length and Width, and set Wall width (thickness). Check the unit label beside each field before you type. For example, 240 in × 180 in is a 20 × 15 ft room.
Choose Create Room. The panel's Segments count shows Segments: 4.
Inspect the rectangle from above, then in perspective. Each side should meet its neighbor.
⚠ Quick Room can't be undone with the main Undo. If you don't like it, use Clear all (the eraser button) to start over. Clear all removes every wall in the plan, so use it only on a plan with nothing else you want. Check that Segments reads 0 before continuing.
Create Room is disabled while you're drawing walls; its tooltip reads Finish drawing first. Finish drawing first.
Drawing wall points is for any outline.
Choose Start creating (the pen button, tooltip Start creating walls). The status changes from Idle to Drawing.
Click the first corner, then click each next corner. Angle snapping straightens a click that's slightly off horizontal or vertical.
Choose Finish drawing when the outline is done.
Inspect the result before assuming it's closed.
If your last side stops short of the first corner, no floor appears. Select the wall beside the gap and drag its open endpoint onto the starting corner. The outline closes and the floor appears.
⚠ Fix the endpoint. Don't lay a short extra wall over the gap. Overlapping walls hide the problem and cause trouble later.
Check the whole boundary in top view, then perspective.
Click a wall. Its highlight confirms the selection, and the Edit Wall section shows its Length, Thickness and Height.
Move a corner. Drag an endpoint. Note that the shared corner moves with its neighbor: both walls change, and so do both lengths. If you only look at the wall you grabbed, you'll miss that the next wall went diagonal. To fix it, drag the corner back.
⚠ The main Undo doesn't cover wall edits. Correct the endpoint directly.
Set height and thickness. Enter Thickness and Height, then choose Apply to selected (the check button). In the lesson, 8 in thick and 96 in tall. The readouts below the fields confirm the new values. Nothing changes until you apply.
You can type a wall's Length, too, but it's usually quicker to drag endpoints.
💡 Edit one wall at a time and check it in perspective. A lower wall beside its neighbors is obvious from the side and invisible from above.
Color and texture (wallpaper, paint, flooring) are separate from size.
Select a wall. Choose Wall color (the palette button) and pick a color.
Apply to selected colors just this wall. Apply to all walls colors every wall.
For an accent, select one wall, choose Choose wallpaper, pick a texture, then Apply to selected.
For the floor, click inside the room. Floor Information shows the floor's Area and Vertices.
Choose Floor color or Choose floor texture, then apply it with the button under the floor controls. There are separate buttons for the selected floor and Apply to all floors.
[SCREENSHOT 2 — Green walls, one striped accent wall, wood floor, perspective view]
⚠ Do the base first, the accent last. Apply to all walls overwrites every wall, including one you've already given an accent. In the lesson: solid green on all walls first, then the striped texture on the back wall only.
Clear the selection highlight before judging a finish. The highlight tints the surface.
Walls and floor styles save with the plan. Which textures you see depends on your plan and workspace, so choose a finish available to you. If you see No wallpaper textures or No floor textures, none are available to you at the moment.
Look at pattern size and repetition in perspective. A wood floor that looks busy can be swapped for a quieter one.
Look at the full shell from top view, then perspective. Save, reopen the plan, and confirm the walls, heights and finishes are still there.
There's no floor in my room. The outline isn't closed. Find the loose endpoint and drag it onto the corner it should meet.
I made a mistake with Quick Room and can't undo it. Use Clear all. It removes all walls, so only use it on a practice plan.
I moved one corner and two walls changed. Corners are shared. Drag it back, then check both neighbors.
My thickness or height didn't change. Choose Apply to selected after you type the value.
Create Room is greyed out (tooltip "Finish drawing first"). You're still in drawing mode. Choose Finish drawing.
All my walls changed color. You used Apply to all walls. Re-apply the original to the accent wall alone.
The wallpaper or floor texture button is disabled. No wall or floor is selected, or no textures are available to your account.
I can't click a floor. Click inside the room in top view, not on a wall.
Choose Wall in the toolbar to open the Walls panel in top view. For a rectangle, enter Length, Width and Wall width under Quick Room (center) and choose Create Room; the Segments count shows 4. For any other outline, choose Start creating, click each corner, then choose Finish drawing.
A floor only shows when the wall outline is closed. If your last wall stops short of the first corner, select the wall beside the gap and drag its open endpoint onto the starting corner. The floor then appears. Don't lay a short extra wall over the gap; overlapping walls hide the problem.
Not with the main Undo. Quick Room and wall edits aren't covered by the main Undo in the current editor. Use Clear all, the eraser button, to remove every wall and start over. Because Clear all removes every wall in the plan, use it only on a plan with nothing else you want.
Click a wall, type Thickness and Height in the Edit Wall section, then choose Apply to selected, the check button. Nothing changes until you apply. The Academy lesson uses 8 in thick and 96 in tall. Edit one wall at a time and check it in perspective, since a lower wall is invisible from above.
Walls share corners, so dragging an endpoint moves the shared corner of its neighbor too: both walls change and so do both lengths. If you only look at the wall you grabbed, the next wall may have gone diagonal. Drag the corner back, because the main Undo doesn't cover wall edits.
Apply to all walls in the Walls panel overwrites every wall, including one you already gave an accent. Apply the base color to all walls first, then the accent texture to the one wall with Apply to selected. If it already happened, re-apply the accent to that wall alone.
