CONNECT AT CORNER
This garage wall continues the house wall from the far side — pick the offset and the run shifts over square, or keep it IN LINE if the walls should align.
DETACHED GARAGE FOUNDATION
Grade beam hangs off grade with a 4" slab sloping 1/8"/ft to the door on graded fill; thickened edge pours one LEVEL monolithic slab — 4" field, 1'-0" edge, 45° taper, on gravel; frost wall stands 8" concrete on a strip footing at the house's footing depth, with the same sloped slab.
Layers follow AIA-style CAD names (A-WALL-EXT, S-SLAB…) so drawings convert cleanly to AutoCAD/DXF.
Commands assign layers automatically — the layers organize themselves, so nobody manages them by hand.
Views (PLAN, FLOOR, ELECTRIC…) are display groupings only; the layer taxonomy is the source of truth for export. Layers can be shared across views — e.g. walls show in both PLAN and ELECTRIC but are only edited in PLAN.

An attached garage hangs off the house: click your first corner ON the house outline, draw the three legs out, around, and back, and land the last corner ON the house too. Missed it? No trouble — grab the corner and drag it onto the house.
