Overview
After generating your Flooring Areas, you can modify them to match the planned flooring installation.
Common edits include:
Adjusting the flooring boundary
Adding additional corners
Simplifying the boundary
Dividing one Flooring Area into multiple materials
Excluding permanent fixtures from flooring calculations
These tools allow your flooring quantities to represent the finished installation—not simply the room layout.
RENDR Principle
Edit the flooring to match the installation—not the room.
Rooms describe spaces.
Flooring Areas describe flooring materials.
Once generated, Flooring Areas can be edited independently of the rooms they originated from.
Before You Begin
Before editing Flooring Areas:
✔ Finish editing the wall layout.
✔ Generate Flooring Areas.
✔ Confirm the Flooring Area already exists.
✔ Review the overall floor plan for accuracy.
Major wall edits are generally easier to complete before making detailed flooring adjustments.
Choosing the Right Tool
If You Want To… | Use |
Change the flooring shape | Edit the boundary |
Follow a complex edge | Insert a vertex |
Simplify the boundary | Remove an unnecessary vertex |
Split one material into two | Divide the Flooring Area |
Remove permanent fixtures from calculations | Exclusion Areas |
Selecting a Flooring Area
To edit a Flooring Area:
Enter Flooring Mode.
Select the desired Flooring Area.
Review the highlighted boundary.
Confirm the Flooring Area information is displayed.
Once selected, Flex makes the Flooring Area available for editing using the tools supported on your platform.
Editing the Flooring Boundary
Use boundary editing whenever the flooring installation differs from the generated room outline.
To reshape a Flooring Area:
Select the Flooring Area.
Drag an existing boundary vertex to a new location.
Release the vertex.
Review the updated flooring boundary.
As the boundary changes, Flex automatically recalculates the Flooring Area.
After completing the edit, confirm the boundary still represents the intended flooring installation.
💡 Pro Tip
Zoom in before editing around angled walls, fireplaces, cabinetry, or other detailed areas.
Adding a Vertex
Sometimes additional corners are needed to accurately represent the flooring layout.
To add a vertex:
Select the Flooring Area.
Insert a new vertex along the desired boundary segment.
Move the new vertex into position.
Review the updated boundary.
Additional vertices are commonly used around:
Fireplaces
Stair openings
Kitchen islands
Built-in cabinetry
Angled walls
Flooring transitions
Only add vertices where the flooring actually changes direction.
Removing a Vertex
If the Flooring Area contains unnecessary corners, simplify the boundary by removing them using the editing tools available for your platform.
A valid Flooring Area must always remain a closed polygon.
Removing unnecessary vertices makes future editing easier without changing the intended flooring installation.
Dividing a Flooring Area
One Flooring Area can represent multiple flooring materials until you divide it.
Use Divide whenever one installation area contains different flooring materials.
Examples include:
Hardwood transitioning to tile
Shower floors
Mudrooms
Entryway tile
Decorative inlays
Accent flooring
To divide a Flooring Area:
Select the Flooring Area.
Choose the Divide or Cut tool available on your platform.
Define the cut across the Flooring Area.
Review the resulting Flooring Areas.
If the proposed cut cannot create two valid Flooring Areas, Flex cancels the operation without changing the existing Flooring Area.
Understanding Exclusion Areas
Some permanent features should not contribute to flooring quantities.
Examples include:
Fireplaces
Stair openings
Kitchen islands
Built-in cabinetry
Bathtubs
Other permanent fixtures
Depending on the project and platform, Flex supports excluding these areas from flooring calculations.
Excluded areas reduce the calculated install area without requiring you to reshape the outside flooring boundary.
Understanding Flooring Calculations
When reviewing a Flooring Area, you may see several calculated values.
Measurement | Meaning |
Gross Area | Total area inside the Flooring boundary. |
Excluded Area | Area removed from the flooring calculation. |
Net Install Area | Gross Area minus excluded areas. |
These values update automatically whenever the Flooring Area changes.
Reviewing Your Flooring
Before estimating or exporting:
Verify | Why It Matters |
Flooring boundaries match the installation | Prevents incorrect quantities. |
Material transitions occur in the correct locations | Ensures accurate takeoffs. |
Exclusions appear where needed | Prevents overstating material quantities. |
Flooring labels are readable | Improves plan clarity. |
Gross and Net Install Areas appear reasonable | Confirms the flooring calculations. |
Troubleshooting: I Can’t Edit My Flooring Area
Check | Recommended Action |
Are you in Flooring Mode? | Switch to Flooring Mode. |
Is the Flooring Area selected? | Select the Flooring Area before editing. |
Is another Flooring tool active? | Return to the normal selection workflow. |
Still can’t edit? | Zoom in and verify you’re selecting the intended Flooring Area. |
Troubleshooting: My Vertex Won’t Move
Check | Explanation |
Does the move create an invalid Flooring Area? | Flex prevents invalid geometry. |
Is the boundary snapping nearby? | Review nearby geometry and try again. |
Is another Flooring Area adjacent? | Review neighboring Flooring Areas before continuing. |
Troubleshooting: My Divide Didn’t Work
Check | Recommended Action |
Did the cut begin on the Flooring boundary? | Start the cut from the boundary. |
Did the cut end on the opposite boundary? | Complete the cut across the Flooring Area. |
Would the cut create two valid Flooring Areas? | Adjust the cut and try again. |
Troubleshooting: My Square Footage Changed
What Changed? | Why |
Boundary edited | Area recalculated automatically. |
Flooring divided | Each Flooring Area now has its own calculated area. |
Exclusion added | Excluded area is removed from the Net Install Area. |
Updated quantities are expected after flooring edits.
Platform Notes
Web
The Web editor supports selecting Flooring Areas, reshaping boundaries, inserting and removing vertices, dividing Flooring Areas, reviewing flooring calculations, renaming Flooring Areas, and linked flooring geometry where applicable.
iPhone & iPad
The iOS editor supports selecting Flooring Areas, editing flooring boundaries, adding vertices, dividing Flooring Areas with the Floor Cut Tool, working with exclusions, reviewing flooring calculations, merging Flooring Areas, and touch-optimized flooring editing workflows. Available tools may differ slightly between iPhone and iPad.
Best Practices
💡 Finish editing walls before making detailed flooring adjustments.
💡 Keep Flooring Areas as simple as possible while accurately representing the installation.
💡 Divide Flooring Areas only where flooring materials change.
💡 Use Exclusion Areas for permanent fixtures instead of unnecessarily reshaping the outside boundary.
💡 Review flooring calculations before estimating or exporting.
Common Mistakes
Editing the Room Instead of the Flooring Area
Changing the flooring installation requires editing the Flooring Area—not the Room.
Adding Too Many Vertices
Only add vertices where the flooring boundary changes direction.
Extra vertices make future editing more difficult.
Reshaping Instead of Using Exclusions
When a permanent fixture occupies floor space, exclusions often provide a cleaner solution than reshaping the outer boundary.
Skipping the Final Review
Every flooring edit updates the calculated quantities.
Review the finished Flooring Area before moving on.
Frequently Asked Questions
Can I reshape a Flooring Area after it’s created?
Yes.
Select the Flooring Area and edit its boundary using the tools available for your platform.
Can I add additional corners?
Yes.
Insert additional vertices wherever the flooring boundary requires more detail.
Can I remove unnecessary corners?
Yes.
Simplifying the boundary makes Flooring Areas easier to maintain while preserving accurate calculations.
When should I divide a Flooring Area?
Divide a Flooring Area whenever different flooring materials are installed within the same area.
When should I use an Exclusion Area?
Use exclusions whenever a permanent feature occupies floor space that shouldn’t contribute to flooring quantities.
Why did my square footage change?
Gross, Excluded, and Net Install Area values update automatically whenever you edit a Flooring Area.
