The fields

Mark

The elevation's tag off the schedule, such as CW-1 or SF-2. Each mark is used once.

Source (sheet)

Where it came from, such as A4.01, or A2.01 detail 3. It's printed with the results so anyone can find it.

Wind zone

Where it sits on the building. Both 4 and 5 checks it both ways when you don't know yet. Zone 5, corner is within the corner distance of an outside corner; Corner at the left end or right end puts only that end in Zone 5 and the rest in Zone 4.

Curtain wall, storefront, window wall

The family. It sets which systems are checked and what is checked (storefront sills and heads sit in a receptor and aren't checked as horizontals; curtain wall sills and heads are).

System type

Leave it on the standard lines, or pick one system depth to answer on.

Faces

North, east, south or west. Only used for the energy code's SHGC limit in the 2015 and 2018 IECC; left unset, the stricter south, east and west limit is used.

Width, height

Feet and inches: 24'-0", 24', 24-6, 288" and 24 (feet) all work. Fractions like 10'-4 1/2" too. When you've given the bay widths, a new width changes the last bay (the bays before it give way only if it would come out under 12"); a new height changes the top row of lites the same way.

Flat head, sloped, each vertical

A sloped head takes the left and right jamb heights; Each vertical takes a height at every line, left jamb to right jamb. Each vertical is then sized on its own height.

Verticals, horizontals

The number between the jambs, and between head and sill. Equal bays and equal lites unless you give them below.

Bay widths, left to right

Optional: each bay's width when they aren't equal, such as 5'-0", 5'-0", 4'-0". They must add up to the width.

Horizontals, height above sill

Optional: each horizontal's height above the sill, when the lites aren't equal.

Check the jambs

On by default: a jamb carries half a bay over the full height, because frames are rarely fastened up the jamb. Turn it off only where the jamb is fastened to the structure along its height.

Head receptor

Storefront only, on by default. Off means the head is fastened and won't take the structure's movement (said on the report).

Tie-backs (anchors)

The head and sill are always anchored. Add a tie-back for each intermediate anchor the wall sections show, as a height above the sill. Only add anchors the drawings show; the results suggest where one would help (Try a tie-back at...), and that stays an option until the structure is there to take it.

A mullion with tie-backs is checked as one member continuous over its anchors (the Mullions section can switch to simple spans).

Drawing on the elevation

Pick a tool above the drawing, or use its key:

S, Select

Click a line to select it; drag a vertical, horizontal or tie-back to move it; drag the gold grips to change the width and height. Drags move in 6" steps (hold Alt for 1"); the arrow keys move a selected line 1", Shift for 1 ft. A bay stays 12" wide and a lite 12" high at least.

V, Vertical / H, Horizontal

Click to add a line where you click.

T, Tie-back

Click at a height to add an anchor there.

D, Door

Click a bay to put a door in it: no sill is checked there, and the door isn't a glass lite.

P, Spandrel

Click a lite to make it spandrel.

M, Measure

Click two points to read the distance.

Esc

Back to Select.

Tip. Undo and redo are under the drawing. Copy makes a new elevation from the one you're on, which is quickest for a family of similar types.
