Overview
In Flex, you never draw rooms manually.
Instead, Flex continuously analyzes your wall layout. As soon as walls or Room Dividers create a continuous enclosed boundary, Flex automatically detects the space as a room.
If you later edit the surrounding walls or Room Dividers, the room updates automatically to match the new layout.
RENDR Principle
Rooms are created from your floor plan geometry.
If a room isn’t detected correctly, inspect the surrounding walls and Room Dividers rather than trying to edit the room itself.
Creating a Room
Rooms are created automatically.
To create a room:
Switch to Layout mode.
Draw or edit walls until they form a continuous enclosed boundary.
If the space is open but should be treated as separate rooms, add a Room Divider.
Flex automatically detects the enclosed space and creates the room.
No additional drawing or tracing is required.
Selecting a Room
To select a room:
Switch to the Select tool if necessary.
Click (Web) or tap (iPhone/iPad) an empty area inside the room.
When a room is selected:
The room becomes highlighted.
The Attributes panel (or Attributes sheet on iPhone) displays the room’s information.
Room Parameters become available.
Room Elevations become available.
Selecting a room allows you to review and edit its properties. It does not change the room’s geometry.
Renaming a Room
Room names can be changed at any time.
Web
Select the room.
Open the Attributes panel.
Edit the Room Name field.
Press Enter to apply the change.
iPhone & iPad
You can rename a room in either of two ways:
Method 1 — Attributes
Select the room.
Open the Attributes panel.
Tap the Room Name field.
Enter the new name.
Tap Done.
Method 2 — Room Label
Tap the room name displayed on the floor plan.
Enter the new room name.
Tap Done.
The updated name is used throughout the project wherever room names are displayed.
💡Pro Tip: Use room names that match the terminology your team uses during estimating and production.
Reviewing Room Information
Each room includes information that updates automatically as the floor plan changes.
To review room information:
Select the room.
Open the Parameters tab.
Depending on the project, available information may include:
Room Area
Room Perimeter
Paintable Wall Area
Paintable Ceiling Area
Total Paintable Area
Kitchen & Bath quantities
Door count
Window count
Review these values before moving on to flooring, estimating, or exporting.
Viewing Room Elevations
Room Elevations provide a wall-by-wall view of the selected room.
To view Room Elevations:
Select the room.
Open the Elevations tab in the Attributes panel.
Review each generated elevation.
Use Room Elevations to verify:
Door locations
Window locations
Wall layout
Overall room configuration
Because Room Elevations are generated from the floor plan, keeping your wall layout accurate results in more accurate elevations.
💡Pro Tip: Tapping the elevation in the attributes panel will automatically open the gallery view, allowing you to view a larger elevation with more detail.
Splitting a Room
Large open spaces often function as multiple rooms without physical walls separating them.
Instead of drawing a wall that doesn’t exist, use a Room Divider.
To split a room:
Select the Room Divider tool.
Draw the Room Divider between existing walls or Room Dividers.
Complete both connections.
Flex automatically detects the new room boundaries.
The floor plan remains open while each space becomes its own room.
Don’t use a physical wall simply to create another room. If no wall exists in the real space, use a Room Divider instead.
Rooms and Flooring
Rooms and Flooring Areas are managed independently.
Rooms define enclosed spaces.
Flooring Areas define flooring materials.
A single room can contain multiple flooring materials.
Likewise, the same flooring material can continue across multiple rooms.
If a Room Isn’t Detected
If Flex doesn’t create the room you expect:
✔ Verify the walls form a continuous enclosed boundary.
✔ Zoom in and inspect every wall connection.
✔ Look for small gaps between wall endpoints.
iPhone & iPad
If nearby wall corners almost meet but aren’t connected, use Auto-Clean.
Auto-Clean searches for nearby wall connections and can repair small gaps that prevent room detection.
Review the proposed changes before applying them.
Best Practices
Finish major wall edits before naming rooms.
Review room areas before creating Flooring Areas.
Use Room Dividers for open-concept layouts.
Review Room Elevations after significant layout changes.
Use Fine-Tune (Auto-Clean) when nearly connected wall corners prevent room detection.
Common Mistakes
Trying to Edit the Room Instead of the Walls
Rooms are generated from surrounding wall geometry.
If a room looks incorrect, inspect the surrounding walls or Room Dividers first.
Using Physical Walls Instead of Room Dividers
Only draw walls that exist in the actual space.
Use Room Dividers whenever you need separate rooms without adding physical construction.
‼️ Ignoring Small Gaps
Even very small gaps can prevent Flex from detecting a room.
Zoom in and inspect each wall connection carefully.
Frequently Asked Questions
Why isn’t my room appearing?
Rooms are created only when walls and Room Dividers form a continuous enclosed boundary.
Inspect nearby wall connections for small gaps, overlaps, or missing connections.
Why did two rooms merge?
A wall or Room Divider no longer creates a complete boundary between the two spaces.
Reconnect the surrounding geometry to separate them again.
Can I rename a room later?
Yes.
Room names can be changed at any time using the Room Name field in the Attributes panel. On iPhone and iPad, you can also rename a room by tapping its room label directly on the floor plan.
