AI Wall Detection

The AI detects wall segments on your floor plan and calculates total wall linear footage.

Steps

1. Walls appear as polylines overlaid on the drawing.
2. Walls only and All Takeoffs give two items in a "Walls" subfolder of Auto Takeoffs: "Perimeter Walls" (the building's outside walls) and "Interior Walls" (all the others). The subfolder header shows the total wall linear footage (LF). Walls by type instead gives one item per wall type (for example "Type P1"), plus an "Untyped" item for interior walls it could not match; perimeter walls it could not match stay in Perimeter Walls. To split walls you already have, click the "By type" button on the Interior Walls row. If the sheet has no wall tags or legend, you keep the Perimeter Walls and Interior Walls totals (see Walls by Type). Faint, extra-wide bands drawn in screened gray lines, typically existing construction, are set aside in a "Faint Walls (review)" item rather than counted with the walls; glazing read from such lines goes to "Faint Glazing (review)". Look them over, then keep, move or delete them.

Notes

• •A wall counts as perimeter when the outside of the building is on one side of it and a room is on the other. If the plan shows only part of the building, walls along the cut edge of the plan can count as perimeter; check them, and use Reclassify to move any interior ones into Interior Walls.
• •Projects whose walls were detected before the perimeter split keep a single "Walls" item until you run walls on that sheet again.
• •By default, wall LF excludes door openings.
• •To include them, select a wall takeoff (Perimeter Walls, Interior Walls, or a wall type after Walls by type) and check "Include door openings (+3' per door leaf)" in the Measure panel. Each door leaf credited to that takeoff adds 3 LF (a double door adds 6 LF). Each door is credited to the nearest wall takeoff on its sheet.
• •Walls only also notes the doors it finds, so this works without a Door count (the Measure panel then says "Doors found by the walls run"). Walls by type does too on a sheet with no walls yet; when it reuses the walls you have (as the By type button always does), it finds no doors. A Door count or All Takeoffs run on that sheet replaces the walls-run doors, and the credit then follows the door takeoff, including any doors you delete. Adding a door to a door takeoff by hand on that sheet moves the walls-run doors into the door takeoffs, where they show and keep counting.
• •You can edit wall vertices with the Select tool like any other measurement.
