Adding pocket and barn doors
Pocket doors slide into the wall; barn doors slide across it. Both eliminate the swing arc; here's how to add each.
Pocket and barn doors save the floor space a swinging door would waste — ideal for tight spots and closets. A pocket door slides into the wall cavity and disappears; a barn door rides a track on the face of the wall. Neither has a swing arc to keep clear, so Flow Check doesn't reserve one.
This page covers placing each type, setting the width and track length, and seeing the hardware in 3D.
Step by step
- 1
Pick the door type from the Build Panel
Build Panel → Doors section. Two tiles: Pocket Door and Barn Door. Click the type you want.
- 2
Click the wall
Click on the wall where the door goes. The door lands at a default position; drag along the wall to reposition.

Pocket door — set width and track length
Inspector → Width (typically 28–42 inches). If the wall is shorter than 2× the door width, use the Track Length Override to specify the cavity depth manually.
A pocket door slides into the wall — no swing arc to clear. - 4
Barn door — set width, track, and side
Inspector → Width (28–60 inches). Track Length (door width + 6–12 inches for parking). Side — In Side (mounts on the room side) or Out Side (mounts on the adjacent room's side).
A barn door rides a track mounted on the wall face. - 5
Verify in 3D
Switch to 3D View. Pocket doors render as if open (invisible) or closed; barn doors render with track and hardware visible.
Tips
Pocket doors need a clear stud bay
A pocket door slides into the wall, so that run has to be deep enough and free of plumbing. On the plan, keep that stretch of wall clear of other fixtures.
Track length for a barn door
A barn door needs roughly double its width in wall to slide onto. Set the track length so the open door has somewhere to go.
Common mistakes
A barn door over a switch or outlet
The door and its track cover the wall face when open. Keep switches and art off the wall the barn door slides across.
Expecting a swing clearance
These doors have no swing arc, so don't leave the quarter-circle clear the way you would for a hinged door — that space is yours to use.
Frequently asked questions
What's the difference between a pocket and a barn door?
A pocket door slides inside the wall cavity and disappears; a barn door slides across the face of the wall on an exposed track.
Do they need swing clearance?
No — neither has a swing arc, so Flow Check doesn't reserve the quarter-circle a hinged door needs.
How do I set the barn door's track length?
Select it and set the width and track length in the Inspector. Allow about double the door width so it has wall to slide onto.
Can I use a pocket door in any wall?
On a real build the wall must be deep enough and clear of plumbing where the door pockets. On the plan, keep that run of wall free of other fixtures.
