The toolbar

The toolbar says two things, and each button says exactly one of them. Left of the thin vertical line: what your next click on the model does. Right of it: which panel is open. A lit button means the tool is active or the panel is open — always, in both directions.

Left end

Item	What it does
‹ Projects	Leaves the structure and returns to the projects page. Unsaved work is not kept
AerTwin and the project name	The structure you are in

Tools — what your next click does

Button	What it does
Navigate	Your mouse moves the view: drag to orbit, right-drag to pan, the wheel to zoom, double-click to focus on a surface. Navigate is the absence of a tool
Measure ▸ Point observation	Places a finding at one point on the structure
Measure ▸ Distance	Measures the length along the surface through the points you click
Measure ▸ Area	Measures the area inside a closed outline
Measure ▸ Volume	Measures the material between the surface and a base level that you choose
Advanced ▸ 3D defect	Estimates the concrete missing from a face, against where the sound face used to run
Advanced ▸ Depth profile	Shows how the surface departs from the straight line between two points
Advanced ▸ Section	Cuts the model along a plane so that you can look and measure inside it

Measure and Advanced open a menu above the button. While one of its tools is active, the group button is lit and names the tool — for example, “Measure · Distance”. Click the active tool again, or press Esc, to return to Navigate.

Panels — what is on the screen

Button	Opens
AI defects	The AI’s proposals near your view, and the review. See AI defects and review panels
Photos	The source photographs of a point you pick. See Source photographs
Measurements	The Measurement panel on the left. See The Measurement panel
Instruments	The instruments marked on this structure. See Mark the location of an instrument
Observations	The project’s findings. See The Observations panel

AI defects, Instruments and Observations share the right side of the window. Opening one of them closes the other.

Right end — help and status

Item	What it does
Explain	Turns the screen into a guide: click anything to read what it means, without pressing it. See Ask AerTwin what something means
The flag ⚑	Opens Report a problem. See Report a problem
The bell ◉	Team activity: what members of this project have saved recently. A number counts what is new for you
Status line	The state of the connection and the result of your last action. Read it first when a tool does not respond

Note

A greyed-out button is unavailable in the current state. Hold the pointer over it to read why — for example, when your role does not allow the action.
