Model a 45-Degree Blind Corner Cabinet in ArchiMaster 3D

Model a 45-degree blind corner cabinet in ArchiMaster 3D by placing a base cabinet box 42 inches wide, 24 inches deep, and 34.5 inches high, then clipping one front corner to a 45-degree angled face in the cabinet editor. Add a lazy Susan tray inside the void and generate the cut list from the same model. The software derives every panel dimension from the 3D geometry, so the angled front is reported as a true diagonal length of roughly 17 inches for a 12-inch corner clip, not as the full 42-inch cabinet width. That single difference turns a useful sketch into a fully buildable cabinet. The cabinet and hardware library keeps the box, door, and tray dimensions synchronized as you adjust the corner.

• A blind corner base cabinet starts as a 42-inch-wide, 24-inch-deep, 34.5-inch-high box with a 4.5-inch toe kick; the 45-degree face clips one front corner.
• With a 12-inch clip on each adjacent side, the angled front panel measures about 16.97 inches, not 42 inches.
• A full-circle lazy Susan needs 28 to 32 inches of clear interior diameter, which is why the 42-inch box works and a 36-inch box usually does not.
• ArchiMaster 3D reports the angled panel, blind side, and shelf dimensions from the same 3D model so the cut list stays accurate.

Start with the Cabinet Footprint and Box Dimensions

Open a new kitchen plan in ArchiMaster 3D and drag a base cabinet from the cabinet library into the corner where two lower runs meet. In the properties panel, set the box to 42 inches wide, 24 inches deep, and 34.5 inches high, with a 4.5-inch toe kick and a 3-inch toe kick depth. Rotate the cabinet so the square face points toward the main run and the blind side stays against the adjacent wall. The visible face is the one that will receive the 45-degree panel. If you are working in the Kitchen & Bath edition, standard overlay doors and frameless construction are already the defaults. The 34.5-inch box height leaves room for a 1.5-inch countertop to reach a 36-inch finished counter height.

The 42-inch width is the practical lower limit for a usable full-circle lazy Susan corner. A 36-inch box leaves roughly 24 inches of clear interior after the overlapping run, which is too tight for a 28-inch full-circle tray. A 42-inch box gives the tray enough sweep room without scraping the cabinet sides or the angled face. If a tight floor plan forces a 39-inch box, switch to a kidney-shaped tray and keep the full-circle tray out of the cut list. A 3D home design workflow lets you test these clearances before you order plywood or hardware.

Add the 45-Degree Front and Clip the Corner

Select the cabinet and open the cabinet editor. Choose the front face that will be angled, then apply the diagonal corner or angled front option set to 45 degrees. ArchiMaster 3D clips the corner and redraws the face frame and door. The model no longer uses a square 42-inch-wide front; it draws a short diagonal panel across the clipped corner. For a 12-inch clip on each adjacent side, the diagonal panel is just under 17 inches. If you want a wider visible face, reduce the clip depth to 9 inches, and the diagonal face becomes about 12.75 inches. Either way, the software recalculates the panel geometry and carries it into the cut list.

The panel length math that changes the cut

On a 90-degree corner, a 12-inch clip along each side creates a diagonal equal to 12 times the square root of 2, or 16.97 inches. Cabinetmakers often round this to 16 15/16 inches for the angled front panel. The clip depth is measured along the side panels from the front corner, not along the wall. If you set a 9-inch clip, the diagonal front becomes 12.73 inches, and the lazy Susan clearance changes because the angled face sits farther back. Keeping the clip depth tied to the model means the cut list never outputs a 42-inch front panel by mistake.

Do not angle the blind back corner. The blind side stays full depth against the wall, and the back corner remains square. If you angle both corners, you are modeling a diagonal corner cabinet, not a blind corner, and the cut list will output two angled panels and a different shelf set. In the ArchiMaster 3D product lineup, the blind corner preset keeps the wall side square and the visible face angled. That single setting saves up to a full sheet of material on a typical remodel because the shop cuts one diagonal face instead of two.

“A blind corner cabinet is a geometry problem first and a cut list second. Model the true 45-degree face in the software, and the saw does not care how confident you feel.”, ArchiMaster 3D Journal

Model the Lazy Susan Insert and Check Clearances

With the cabinet box and angled face set, insert a lazy Susan assembly from the rotating shelf library in ArchiMaster 3D. Choose a full-circle tray for a 42-inch box or a kidney tray for tighter corners. Set the tray diameter in the properties panel, and watch the 3D preview for interference with the angled face and the blind side. A full-circle tray typically needs 28 to 32 inches of clear interior diameter, measured at the widest usable point. The 3D model shows exactly where the tray sweeps past the cabinet edges, which is hard to confirm from a plan view alone.

• Confirm the tray diameter clears the angled front face at its narrowest point.
• Check that the door opens far enough to let the tray rotate without binding.
• Add 1 inch of clearance between the tray edge and the cabinet sides.
• Reduce the tray diameter by 2 to 4 inches if the box is a 39-inch corner.

Why a full-circle tray wins in a 42-inch box

A 42-inch box creates a clear interior pocket large enough for a full-circle tray to rotate without dead space near the hinge. Homeowners reach more of the stored items, and the mechanism often costs less than a kidney-shaped hardware set because it uses a simpler pivot. A kidney tray fits a 39-inch box, but it tends to hide items at the back of the kidney shape. Let the 3D model show both tray styles side by side before you finalize the cabinet size and the clip depth.

Generate the Cut List Without Errors

Open the project cut list in ArchiMaster 3D after the cabinet and tray are placed. The cut list derives dimensions from the 3D model, so the angled panel, blind side, and shelf parts are labeled with their true sizes. The angled front appears as a single diagonal panel, usually around 16 15/16 inches for a 12-inch clip, rather than a 42-inch-wide rectangle. Check the parts list for the two side panels, the back panel, the bottom shelf, the toe kick, and the angled face. If the tray needs fixed shelf supports, add those in the model so they appear in the hardware list as well.

Common Mistakes That Break the Model

The most common mistake is angling both corners and ending up with a diagonal corner cabinet. The second is leaving the front panel at 42 inches in the properties, which sends a too-long panel to the cut list. The third is placing the lazy Susan without checking the 3D sweep, then discovering the tray hits the angled face after the cabinets are ordered. A fourth is setting the cabinet height to 36 inches and forgetting the countertop, which pushes the finished counter above standard height. Model the finished assembly once in ArchiMaster 3D, and the software keeps each part consistent when the clip depth or tray diameter changes.
