Updating an Existing Building Model using a Sketch

I'll connect to your open Revit model, read Level 1's existing geometry, then add the walls, doors, gym wing and rooms from your sketch.

Now let me read the existing walls on Level 1 to get the coordinate frame.

Revit 2024+ uses Int64 element IDs; adjusting.

All 12 rooms are bounded with sensible areas. Let me look at the plan to check door swings and joins.

Rooms, walls and the gym wing look right. One fix needed: the single classroom doors swing into the corridor, whereas your sketch shows them swinging into the classrooms. Flipping those.

The image is too small to read swing direction at this scale, so I'll verify it geometrically from each door's extents.

Confirmed via geometry — the singles now swing into the corridor (I misread the first render). Flipping back and re-verifying.

Level 1 is updated in your open model (not saved yet). Here's what went in:

• Walls: 22 interior partitions (Interior – 4 7/8" 1-hr, Level 1 to Level 2), forming an 8'-wide east–west corridor, eight classrooms, the lobby, the gym/lobby wall, the cafeteria wall and the library-wing divisions.
• Gym wing: five Exterior – Brick on CMU walls tracing your gray gable outline, about 46' wide and running ~65' north to the peak, plus a matching foundation slab. To open the bar into the gym, I deleted the north entrance storefront and its door, and shortened the two adjoining storefront walls.
• Doors: 18 single 36"×84" classroom doors, two per room, swinging into the rooms as sketched. I also loaded Door-Double-Flush_Panel 72"×84" from the Revit library for six double doors: two gym doors, the library, the bottom library-wing room, the corridor end in the library wing, and the cafeteria.
• Rooms: 12 rooms with tags, all fully bounded:
• Library: 967 SF
• 8 Classes: 377–427 SF each
• Lobby: 1,321 SF
• Gym: 2,633 SF
• Cafeteria: 3,843 SF

Two room-separation lines stop the lobby from running into the corridors.

Judgment calls and things to check:

• Canopy columns inside the gym: The existing north entrance canopy (a Level 2 floor plus four columns) now sits inside the gym. Your sketch erased that area, but I didn't delete it. Tell me and I'll remove it.
• Short blue lines through the library doors: There are two short vertical blue strokes through the library double doors. Read as walls, they would split each doorway in half, so I left them out. If you meant two separate rooms with a single door each, I can change that.
• Gym wall height: I ran the gym walls up to Level 3 (24') for gym height. The rest of the walls stop at Level 2.
• Not modeled: The gray "Raised Stage" line wasn't modeled. I also didn't create rooms for the unlabeled library-wing spaces or the corridor, since they had no purple label.

The main build is one undo step (Ctrl+Z → "Level 1 update from sketch"), and the door-swing fixes are two separate steps after it. Want me to save, or remove the old canopy first?

Starting with the canopy. I'll identify which Level 2 slab and columns belong to the north entrance.

North canopy is slab 378250 plus four round columns at y = 68.8'. Now making all four changes as one undo group.

All four changes are in the model, and it's still unsaved:

• North canopy removed: I deleted the Level 2 canopy slab and its four round columns. The gym is now clear. The south entrance canopy is untouched.
• Library split: A new partition at x = 26' divides it into two Library rooms of 499 SF and 460 SF. The double door is replaced by two 36" single doors, one into each room.
• Front offices: A partition at x = 28' splits the front-left room into two Offices of 401 SF and 312 SF. Each has its own single door off the space behind.
• Raised stage: I added a Generic 12" floor across the north end of the cafeteria, set 2' above Level 1 and commented "Raised Stage." I placed its front edge at y = 59.42', in line with the end of the cafeteria's west wall; your sketch line sits about a foot further south.

Every new door was checked and swings into its own room. This round is one undo step: "Library/office split, stage, canopy removal."

The Cafeteria room still includes the stage area, since a floor doesn't bound a room. I can add a separation line so the Stage becomes its own room. Should I do that, then save?

I'll add the hip roof on top of the gym walls at Level 3, then the green exterior doors on the gym's two angled north walls. Let me check available roof types first.

The roof call needs its output parameter handled differently in IronPython. Checking the model state wasn't left mid-transaction, then retrying.

Clean state — the failed attempt was rolled back. Retrying with the corrected call.

Both succeeded. Let me look at it in 3D to confirm the roof sits correctly.

The gym now has a hip roof, and there are four exterior double doors on its north walls:

• Hip roof: It uses the same Wood Rafter 8" – Asphalt Shingle type as the main building. It sits at Level 3 (24') with a 4:12 slope on all five edges and a 1' overhang past the brick. The ridge comes to about 32'-8".
• Exterior doors: I loaded Door-Exterior-Double at 72"×84" from the Revit library. There are two pairs on each angled north wall, spaced evenly along the wall, and all four swing outward as exits.

The 3D back view shows it sitting cleanly against the classroom bar, and both new doors on the visible angled wall are in place. This round is one undo step: "Gym hip roof and exterior doors."

The roof's south edge also slopes down toward the bar's wall. If you'd rather it butt flat against the bar, I can turn the slope off on that edge. The model is still unsaved; want me to save it?
