AI takeoffs let you identify and measure elements on a plan page without drawing each measurement by hand. You describe what to find or let AI detect elements, and it locates matches, creates symbols, and places measurements on the canvas.

From the takeoff sidebar, click the + menu and select AI Analysis. The AI analysis panel renders inline in the sidebar with a prompt input and a Detect elements button.

You have two ways to start. Type a description of what to measure in the prompt field (e.g., "interior doors and windows") and submit, or click Detect elements to let the AI scan the page on its own. Either way, a spinner with Analyzing page appears while detection runs. If detection stalls, a Retry button appears.

Once detection completes, elements appear grouped by measurement type: Area, Linear, and Count. Each group lists the element names the AI identified on your plan -- things like doors, windows, pipes, or square footage regions.

Check the boxes next to each element you want to analyze. The selection header shows the count and cost, for example 3 selected (2 credits/page). If a group has many elements, expand the full list with the chevron button at the bottom.

If the AI missed something, click the + button next to any group header to insert a new row. Type the element name and it auto-selects. Custom elements behave identically to detected ones during analysis.

With your elements selected, click Run in the top-right corner of the panel. You can also select multiple pages to run the analysis across -- the cost scales per page. The Run analysis confirmation dialog displays the exact credit cost and asks you to confirm before proceeding.

The analysis creates a new takeoff layer named with your name, the measurement types, and a version number. AI-generated symbols on this layer are marked with (AI) in the sidebar so you can distinguish them from manual measurements.

After analysis completes, a Review detected elements dialog may appear. It lists what the AI found, grouped by category, with checkboxes to include or exclude each one. Deselect anything that looks incorrect, then click Continue to finalize. Click Cancel to discard the analysis and return to the default layer.

AI-placed measurements appear on the canvas like any other takeoff. You can select, move, resize, or delete individual shapes. Adjust symbol properties, rename elements, or add cutouts just as you would with manual measurements.

AI analysis works best on clearly drawn plans with distinct symbols. Set your page scale before running analysis so measurements are accurate. Use descriptive prompts -- "interior doors" rather than "doors" helps the AI produce more precise results.
