Draw the room. Drop cabinets onto the walls. Open any one and lay out its face the way your shop actually makes it. Plan, elevation and 3D come from the one model, so they cannot disagree.
This is the face editor on a 30″ double-door base: the pair opening is selected — 25 × 27¼ — and beside it are the controls that make it yours. Split the opening with a rail or a stile; pick the front style (slab, shaker, fluted, custom); set the frame widths — 2″ top, 1¼″ bottom, 3″ left, 2″ right here — and the rail and stile defaults the job carries. Change a number and the parts redraw.
