Recipes

Real tasks, each solved by a short chain of operations. Every recipe gives the operations in the order they sit in the list, their settings, and the values a few elements end up with.

Doors take the number of the room they open into

Task: every door gets a number made of the room it leads into: D-1.04. Exterior doors, with no room on that side, get D-EXT. The numbers must stay right when rooms are renumbered, so the configuration is run again before each issue.

Operations, in this order:

1 · Room Data — Door room

2 · Prefix Suffix — Door prefix

Result:

Running it again after room 1.04 became 1.12: operation 1 writes 1.12, operation 2 makes it D-1.12. Doors whose room did not change end up exactly as they were.

Why it works:

• The order matters. Room Data first replaces the whole value with the current room number; Prefix Suffix second adds D- to it. The other way round, the prefix would be added and then overwritten.
• Skip existing prefix/suffix stops D- from being added twice if Prefix Suffix ever runs on its own.
• To room follows the way each door was placed in Revit. If your doors are placed the other way, use from room. Check a few before running on the whole model.

Variations:

• Two doors into the same room get the same number. To tell them apart, add a Unique Identifier that numbers doors into a second parameter, restarting for each value of Door Number, and join the two with Combine Values: D-1.04-1, D-1.04-2.
• Want the room name too? Replace operation 2 with Combine Values.

Grid location on columns

Task: every structural column carries its grid location, B/3, for the column schedule and for the site. Columns sitting off a grid also show by how much.

1 · Nearest Grids — Column grid

Result:

Why it works: a column within the on-grid tolerance gets just the grid name, so the common case stays short and only the exceptions carry a distance. Moved columns get the new value on the next run.

Unique numbers per level

Task: doors are numbered per storey in reading order: L00-001, L00-002, … then L01-001 on the next floor.

1 · Level — Door storey

2 · Unique Identifier — Door index

3 · Combine Values — Door number

Result:

Why it works: operation 1 gives every door a reliable storey, operation 2 uses it both to restart the series and to order by level, and operation 3 builds the final mark. Each operation writes its own parameter, so running the file again gives the same marks.

Variation: once the marks are issued, turn on Continue numbering in operation 2 — new doors get the next free number and existing ones keep theirs.

Classification codes from a CSV

Task: wall types get a Uniclass code and title from the office classification list, kept in Excel.

1 · Map Values — Uniclass

The CSV — key column first, then one column per target:

Type Mark;Uniclass Code;Uniclass Title
IW-100;Ss_25_10_30;Framed partition systems
IW-150;Ss_25_10_30;Framed partition systems
EW-365;Ss_25_10_20;Masonry wall systems

To get the columns right, open the table, Export the empty one, fill it in Excel and Import it back.

Result:

Why it works: the key and the targets are all type parameters, so each type is written once. UNCLASSIFIED makes missing rows visible in a schedule instead of leaving old values in place.

Conditional values

Task: every room gets its occupant load — area divided by 10 m² per person, rounded to whole people — and rooms above 60 people are flagged as needing a second exit.

1 · Calculated Value — Occupant load

2 · If Then Else — Exit check

Result:

Why it works: the calculation runs first and writes a number; the condition reads that number on the same run. <clear> in Else removes an old note from a room that has become smaller.

Stray elements onto the right worksets

Task: doors and furniture that ended up on Workset1 are moved onto A-Doors and I-Furniture. Elements already placed elsewhere on purpose stay where they are.

1 · Move to Workset — Doors to A-Doors

2 · Move to Workset — Furniture to I-Furniture

Result:

Why it works: the filter limits each operation to elements still on the default workset, so deliberate exceptions are not touched.
