To set up face-frame door parameters in Mozaik, open the cabinet in the Product Editor, go to the Parameters tab, pull in the door-overlay and opening parameters from the Door category, and adjust their values to control your overlay, drawer openings, door-pair gaps, and door outset. This follows Mozaik's official walkthrough of the face-frame construction method's door parameter category. The fastest way to learn how each value behaves is to do a product parameter override, so you can watch the changes update live in the 3D view before you commit them library-wide.
This guide follows Mozaik's official walkthrough. Watch the original on Mozaik's channel:
Before you start: understand parameter hierarchy
Mozaik layers its parameters, so a value can be set at one level and overridden at the product level. The technique used throughout this guide is a product parameter override — changing a parameter on a single product so you can see its effect in a live setting without altering your whole library. If you're new to how Mozaik layers its parameters, Mozaik recommends watching their parameter-hierarchy video first before working through any of the door-parameter videos; an override on one cabinet is the safe way to experiment.
Step 1: Open the cabinet in the Product Editor
Double-click the cabinet (for example, a three-drawer base) to open the Product Editor. Open the 2D/3D Product view alongside it so you can spin the cabinet, toggle layers, and watch construction changes as you edit. Keeping the editor on one side and the viewer on the other lets you see each parameter take effect in real time.
Step 2: Pull in the door parameters
In the Product Editor's Parameters tab, use Select Product Parameter at the bottom and move to the Door category.
Each parameter row has three columns: Parameter, Description, and Value. Clicking a row highlights it, and the blue question-mark icon opens Mozaik's built-in help doc for that parameter — a quick way to read the official definition without leaving the screen.
Highlight the door-overlay parameters you want to work with — the door overlay on the sides (DoorOL), the door overlay top (DoorOLTop), and the door overlay bottom (DoorOLBottom) — and select OK to bring them into the product's parameter list. DoorOL controls the side overlay under the Face Frame construction method.
Step 3: Set the top, bottom, and side overlay
Overlay is measured from the inside edge of the face frame's stile or rail to the edge of the door. Use the dimensioning tool in the viewer (wireframe mode makes this easiest) to see the actual gap.
- Top overlay — Measured from the inside of the top rail to the top of the door. In the example it starts at 1/2"; changing it to 1" pushes that top overlay out to a full inch. Important: this value affects the top of every door and drawer front on the cabinet, not just the topmost one.
- Bottom overlay — Controls the bottom edge the same way.
- Side overlay — Measured from the inside of the stile/rail to the door edge; changing it from 1/2" to 1" widens the overlay on each side.
Watch your reveals. If you set both top and bottom overlays large (for example, both to 1"), the drawer fronts can grow until they touch each other and you lose the reveal between them. Switch to a perspective/field view to confirm the fronts aren't running into one another before you keep the change.
Half-inch, 3/8", or even 3/4" overlays work well with this face-frame method when your center rail is wide enough to support them. If you're aiming for a full-overlay door look instead, you must switch the face-frame construction method to full overlay — that's a separate parameter set covered in Mozaik's full-overlay door-parameter video.
Step 4: Adjust the top drawer opening height
Bring in the top drawer opening height parameter (DwOph). This is the opening height between the top rail and the rail directly below the top drawer.
In the example it's set to 5". Bumping it to 8" enlarges the top drawer's opening and shrinks the other drawer fronts to compensate. This parameter affects only the top drawer opening, and Mozaik automatically resizes the top drawer front to match while preserving the 1/2" overlay you set.
Step 5: Control the gap between a pair of doors
Bring in the pair gap parameter (PrGap) to control the reveal between two doors that form a pair. In the example, a door pair's reveal starts at 1/8"; raising the pair gap to 1" visibly widens the space between the two doors. Use the front view with the cabinet filled and the dimensioning tool to read it cleanly.
Pairs vs. split single doors: The pair gap only applies when the doors are configured as a true pair. If you take a single door and split it, Mozaik adds a center stile between the two halves — so it's no longer a pair gap. Each door then overlays that center stile by the side overlay distance you set in Step 3.
Step 6: Set the door outset
Bring in the door outset parameter (DoorOutset). This is measured from the back of the door to the front of the face frame — how far the door sits proud of the frame.
In the example it's set to 1/8". That small default exists for a practical reason: it's about the thickness of a door silencer, or how far the hinge holds the door off the face frame. Setting it to something like 1" pushes the door well off the frame — useful only to see how the parameter behaves, not as a realistic value.
Step 7: Test safely, then keep or discard
Because this is a product parameter override, you can experiment freely:
- To undo, delete the test parameters one at a time from the product's parameter list, or
- Select Cancel in the Product Editor and don't save — that returns the cabinet to its original library settings.
This lets you dial in real overlay, opening, gap, and outset values on one cabinet and verify them in 3D before rolling them out.
A note on the other door parameters: parameters like applied door (which applies a door to the outside of the face frame and is really a frameless-cabinet setting) and several others stay grayed out under this method — they belong to the full-overlay face-frame construction method, which is a separate setup.

FAQ
Does the top overlay parameter only change the very top door?
No. The top overlay affects the top edge of every door and drawer front on the cabinet. Plan it as a cabinet-wide value, not a per-front one.
Why did my drawer fronts start touching when I increased the overlays?
Large top and bottom overlays grow the fronts until the reveal between them disappears and they collide. Reduce the overlay or check the spacing in a perspective view, and make sure you're leaving room for reveals.
What's the difference between a pair gap and the gap on split doors?
The pair gap controls the reveal between two doors configured as a true pair. If you split a single door, Mozaik inserts a center stile, so the pair gap no longer applies — each half overlays that stile by your side-overlay value instead.
Why is the door outset set so small by default?
A small outset (around 1/8" in the example) roughly matches the thickness of a door silencer or how far the hinge holds the door off the face frame, so the door sits naturally proud of the frame without a large gap.
