Reviewed for Flex Version 3.0

Most wall edits in Flex feel simple—drag a wall, move a corner, or enter a new measurement.

Behind the scenes, however, Flex is continuously rebuilding wall connections, room boundaries, flooring, and dimensions to keep your floor plan accurate.

Although walls appear simple, every wall is connected to one or more corners.

Flex treats these corners differently depending on how they’re connected.

A wall endpoint belongs to a single wall.

Moving an endpoint affects only that wall.

Use wall endpoints when you want to:

A shared wall corner connects two or more walls.

When you move a shared corner, every connected wall updates together.

This allows Flex to preserve the relationships between connected rooms while still letting you reshape the floor plan.

Shared corners are commonly used when:

A T-junction is created when the end of one wall connects to the middle of another wall.

Common examples include:

To create a T-junction:

Flex automatically creates the connection and updates the surrounding wall geometry.

Tip: Zooming in before creating a T-junction makes it easier to confirm the correct snap location.

As walls are edited, Flex may automatically merge or split wall geometry to maintain clean connections.

When a wall connects to the middle of another wall, Flex creates a new wall intersection at that location.

Although this appears as one continuous wall, Flex treats each section independently so nearby walls, dimensions, and room boundaries remain accurate.

When two connected walls become a single continuous wall, Flex may merge them automatically.

This keeps the floor plan organized and avoids unnecessary wall segments.

Users generally do not need to manually manage these behaviors.

Occasionally, dragging a corner causes one wall to separate from the others.

This usually occurs because the requested movement would create impossible or overlapping wall geometry if every wall remained connected.

Rather than creating an invalid floor plan, Flex temporarily separates the affected wall so the edit can continue.

Once the wall is reconnected to another corner or wall, Flex should restore the connection automatically.

This behavior helps preserve clean wall relationships while preventing invalid geometry.

Flex allows walls to move only when the resulting floor plan remains valid.

Movement may stop before reaching your cursor if continuing the edit would create problems such as:

These movement limits are intentional and help maintain an accurate floor plan.

If movement stops unexpectedly, inspect nearby walls and hosted features before continuing.

Flex automatically identifies rooms by analyzing enclosed wall boundaries.

Whenever walls are added, removed, connected, or repositioned, room boundaries are recalculated automatically.

For a room to be detected successfully, its walls must form a continuous enclosed shape.

Even a small gap between connected walls can prevent a room from being recognized.

If a room disappears after editing:

Flooring areas are linked to the surrounding wall geometry whenever possible.

As walls move, connected flooring boundaries update automatically to match the new room shape.

This greatly reduces the amount of manual flooring editing required after making layout changes.

Depending on the edit, you may occasionally need to regenerate or manually adjust flooring if room geometry changes significantly.

Dimensions in Flex are generated automatically from the current wall layout.

Whenever wall geometry changes, Flex recalculates nearby dimensions to reflect the updated floor plan.

This includes:

If dimensions disappear after editing, it is usually because Flex can no longer identify a valid enclosed room or connected wall relationship.

Reconnect nearby walls before manually recreating dimensions.

Flex supports two types of wall geometry.

Physical walls represent actual construction.

They:

Use physical walls for existing or proposed construction.

Room dividers are invisible boundaries used to separate spaces without representing actual construction.

Common uses include:

Room dividers influence room detection but do not represent a physical wall.

Because they are intended only to divide spaces, doors, windows, and openings cannot be placed on room dividers.
