How Flex handles unsaved changes
Overview
As you edit a floor plan, your changes exist only in your current editing session until you save them.
To avoid losing work, make it a habit to save regularly—especially before closing the editor, switching devices, or exporting your project.
RENDR Principle
Save early. Save often.
Undo is for correcting mistakes.
Saving is what permanently records your work.
Saving Your Work
Select Save whenever you’ve completed a meaningful set of edits.
Saving records changes such as:
Wall edits
Door, window, and opening changes
Flooring edits
Object placement
Room names
Measurements
Markup
Space information
Once saved, those changes become the current version of your floor plan.
When Should I Save?
We recommend saving:
After completing major wall edits.
Before exporting.
Before closing the editor.
Before switching to another device.
Before leaving a jobsite.
Anytime you’ve completed an important milestone.
💡 Pro Tip
Get into the habit of saving every few minutes while making significant edits. It’s much easier to save periodically than to recreate work if your editing session is interrupted.
What Happens If I Don’t Save?
Unsaved edits exist only in your current editing session.
If you accidentally:
Close the app
Force quit the editor
Lose power or battery
Restart your device
Experience an unexpected crash
any edits that have not been saved will be lost.
Flex will warn you before intentionally leaving the editor with unsaved changes, but it cannot recover edits from an interrupted session that were never saved
Leaving the Editor
If you attempt to leave the editor with unsaved changes, Flex will ask how you’d like to continue.
Depending on your platform, you’ll be able to:
Save and Exit
Exit Without Saving
Cancel and continue editing
This safeguard helps prevent accidentally discarding your work.
Undo & Redo
Undo and Redo allow you to move backward and forward through your recent edits.
Nearly every editing action creates an undo point, including:
Wall edits
Vertex movement
Door and window edits
Flooring changes
Object movement
Renaming
Markup edits
Undo restores the previous state of the floor plan, including any connected geometry that changed as part of the edit.
Platform Notes
Web
Use the Undo, Redo, and Save buttons in the editor toolbar.
The Save button is enabled whenever the floor plan contains unsaved changes.
If you attempt to close the editor or export with unsaved edits, Flex prompts you to save first.
iPhone & iPad
Tap Save in the navigation bar whenever you’ve completed important edits.
Undo and Redo are available from the navigation bar. When using an external keyboard:
⌘ + Z — Undo
⌘ + Shift + Z — Redo
If you attempt to close the editor or swipe back with unsaved changes, Flex prompts you to save, discard your changes, or continue editing.
Exporting with Unsaved Changes
If you begin an export while your project contains unsaved edits, Flex will ask whether you’d like to:
Save and Export
Export Without Saving
Cancel and return to editing
This allows you to choose whether the export should include your latest changes.
Recovering Previous Versions
If you’ve accidentally saved unwanted changes—or need to recover an earlier version of your floor plan—contact RENDR Customer Support.
In many cases, we can restore a previously saved version of your space.
Note: Only previously saved versions may be recoverable. Unsaved edits cannot be restored.
Best Practices
Save after completing major edits.
Save before leaving the app for any reason.
Save before switching devices.
Save before exporting.
Use Undo and Redo freely while editing.
Common Mistakes
Closing the App Without Saving
Always save before closing the editor. If the app closes unexpectedly, any unsaved edits will be lost.
Assuming Changes Save Automatically
Flex tracks unsaved edits and warns you before exiting, but it does not automatically save your work.
Waiting Until the End of a Long Editing Session
Long editing sessions increase the amount of work that could be lost if the session is interrupted. Save periodically instead.
Frequently Asked Questions
Does Flex save automatically?
No.
Flex tracks unsaved changes and warns you before leaving the editor, but you are responsible for saving your work.
Can I undo multiple edits?
Yes.
Undo and Redo work through your recent editing history.
What if I accidentally lose my work?
If your edits were never saved, they cannot be recovered.
If you need an earlier saved version of your space, contact RENDR Customer Support. We may be able to restore a previous version of the project.
