The panel lives in the 3D Viewport sidebar (N) on the ScaffVisor tab. The ? button in the status strip opens the page of the section you are in.

Before a scaffold exists

Three rows and one button.

Row What it shows
Wall What will be used as the path: selected faces or edges (Edit Mode), a curve, or the base ring of a mesh
Ground Optional terrain mesh. It can be chosen while you are in Edit Mode, so you do not have to leave it
Generate Scaffold Builds the scaffold. It is greyed out, with the reason on hover, when nothing usable is selected

The status strip

With a scaffold selected, the top line shows its name, its total weight, the number of notes (click it to read them), the help button, the viewport options and Delete. Rebuild (Out of Date) appears under it when Live Update is off or the scaffold is very large. A failed build is shown there as well, with the reason.

Viewport options change only what you see: guard rails, braces, ties, side arrows. Hidden parts stay in the bill of materials. Live Update rebuilds after every change; very large scaffolds wait for Rebuild.

Layout

Setting Meaning
System The scaffold system (preset)
Height › From Faces Take each wall’s height from its faces; Offset adds or subtracts a fixed amount (a negative value stops the top deck below the wall top)
Height Used when the path is a curve or edges, or when From Faces is off
Wall Offset Clear distance between the wall and the inner face of the frames. Above 0.30 m inner guard rails are added
Side › Flip Put the scaffold on the other side of the wall
Ends Cover: bays reach or pass the end of the wall. Nearest: total length as close as possible. Inside: never pass the end
Allow › Short Bays Allow the short bays of the system for a closer fit
Path Where the path came from. The button next to it replaces the path with the current selection

The dimmed line under Height shows the resulting top deck height and the number of lifts.

Ground

Set Ground to the terrain mesh. A photogrammetry scan that also contains the ruin is fine.

Setting Meaning
Max Slope Only terrain faces flatter than this angle count as ground, so ruin walls in the scan are ignored
Search Height The ground is probed downwards from this height above the wall base. Keep it below overhangs and wall tops
Base Pad Thickness of sole boards under the jacks
Jacks and Tolerance › Jack Extension Preferred extension of the jacks when compensation frames are chosen
Jacks and Tolerance › Top Deck Tolerance Let the top deck sit up to this much lower than asked, to need fewer compensation frames

The refresh button next to Ground reads the terrain again after you edit it. Dimmed lines show the ground range, the jack range and the number of compensation frames.

If the scan has tall ruin tops next to the scaffold, use a cleaned copy of the terrain as Ground, or lower Search Height.

Parts

Setting Meaning
Timber Grade Deck type of the system, which sets the weights
Add › Toeboards 15 cm toeboards on open edges. They complete the three-part edge protection
Add › Low Decks A deck on top of each compensation frame where the ground is high
Cladding None, net or sheeting. They multiply the number of ties (rule of thumb)

Result

Wall length and bays, frames and legs, braces and ties, weight per square metre, and how much of the weight is estimated. Notes lists what to look at: columns beyond the jack range, corners that are only approximate, parts without a deck. Parts List is folded away; a star marks estimated weights.

Export Bill of Materials writes a CSV to a folder named <your file>_scaffvisor next to the .blend, with the date and time in the name, so earlier exports are kept. The box next to the button chooses EU (semicolon, decimal comma) or US (comma, decimal point) numbers. The folder button opens the folder. A file that has not been saved yet exports to the temporary folder, and a warning says so. The notes are exported too.
