Markup allows you to place visual annotations over a floor plan without changing its measured geometry.

Use Markup Mode to:

Markup does not change:

To modify the measured floor plan, return to Layout or Flooring Mode.

Use Layout and Flooring tools to document the building. Use Markup tools to communicate information about it.

Markup creation and editing are available in the RENDR iOS app on iPhone and iPad.

In Flex 3.0, Web can display existing markup but cannot create or edit it.

On iPhone or iPad:

Markup Mode includes five annotation categories:

Changing editor modes clears the current selection and cancels an unfinished gesture. When you return to Markup Mode, select the annotation tool you want to use again.

Freehand includes:

The Pen creates an opaque freehand line.

The Marker creates a broader highlighting stroke.

Choose the color, size, and fill setting before drawing the new shape.

To use a different appearance, remove the existing item and create a replacement with the desired settings.

The Eraser removes a complete Freehand item. It does not scrub away only part of a Pen or Marker stroke.

To remove a Freehand item:

Only the tapped Freehand item is removed.

Use Undo immediately if you remove the wrong item.

Available Symbols include:

To place a Symbol:

Symbols can snap flush to nearby plan edges. They can also use a nested snapping behavior when placed near two perpendicular edges.

If the Symbol snaps to an unwanted edge:

You can also break a snap by dragging beyond the active snap tolerance.

To resize a Symbol:

To rotate a Symbol:

Symbol rotation snaps in 5-degree increments when Symbol snapping is enabled.

Symbols have a documented color picker and can be edited after placement.

To recolor an existing Symbol:

To add a Text annotation:

If you leave the Text annotation empty, Flex discards it automatically.

To change the wording:

To move the label:

To resize the label:

Small, Medium, and Large size presets are also available.

The inventory does not document changing Text color after placement.

Custom Dimensions are reference annotations. They do not change the measured wall or room geometry.

To create one:

Custom Dimension endpoints can snap to:

Five-degree angle snapping can be enabled or disabled in Settings.

To move an endpoint:

To reposition the label:

To remove the dimension:

With a connected hardware keyboard, Delete or Backspace also removes the selected Custom Dimension.

Each annotation category has its own panel.

Use the panel for the active annotation type to:

On iPad, annotation controls appear in collapsible slide panels.

On iPhone, controls may appear in sheets adapted to the smaller screen.

Flex does not use one global Clear Markup command for every annotation category.

Instead, each annotation type has its own Clear All action.

To clear one category:

For example, clearing Freehand does not automatically clear Symbols, Text, Pinned Notes, or Custom Dimensions.

Use Layers to control which annotations are visible.

Available markup layers include:

To hide an annotation category:

To show it again:

Hiding a layer does not delete its annotations.

Layer visibility is saved on the device.

To reverse a markup action:

To restore an action:

Hardware keyboard shortcuts:

Undo and Redo are disabled in View Mode.

When you are finished creating markup:

Markup cannot be used to:

Markup creation and editing are supported.

Some tools and annotation controls appear in bottom sheets to fit the smaller display.

Zoom in before attempting to interact with small or closely spaced annotations.

Markup creation and editing are supported.

Annotation controls appear in collapsible slide panels.

Apple Pencil can be used for Freehand input.

Markup created in the iOS app can be viewed on Web.

In Flex 3.0, the Web editor does not allow users to:

When a plan contains no markup, the Web Markup section is disabled. Existing markup is non-interactive when displayed.

💡 Choose Freehand colors and sizes before drawing.

💡 Use Symbols for repeatable plan notation rather than drawing the same icon by hand.

💡 Use Text for short labels and Pinned Notes for detailed context or photos.

💡 Use Custom Dimensions only as reference annotations. They do not modify measured geometry.

💡 Hide individual markup layers when the floor plan becomes crowded.

💡 Use Undo immediately after an accidental delete or movement.

💡 Save your changes before reviewing the markup on Web.

Editing behavior varies by annotation type.

For example:

Markup adds communication over the plan.

Use Layout or Flooring Mode to correct the measured geometry.

It depends on the annotation type.

Symbols, Text, Pinned Notes, and Custom Dimensions each provide documented post-placement interactions. Freehand items are primarily created with preset color and size controls and removed with the Eraser.

Yes.

Select the Symbol and use its color picker.

No, not after the freehand markup is created.

Remove the item and recreate it using the desired color.

No.

The Eraser removes the complete Freehand item.

Yes.

Use the Eraser for a Freehand item or delete the individual item from its annotation panel.

Yes.

Use Layers to hide Freehand, Symbols, Pinned Notes, Custom Dimensions, or Text independently.

No.

Web displays existing markup in Flex 3.0 but does not provide markup creation or editing tools.
