The guide
Where Controls & help › Quick tour / Full guide
On the first start the app offers a quick tour or a full guide through every tool, on the sample project. Start it again any time from Controls & help.
Controls & help
Where The ? top right in a project, the ? at the bottom of the projects, or the menu under the project name
The controls for your device, the supported formats, the guides, a link to this handbook and the open-source licences.
The sample project
Where The projects gallery; again from Account › Add the sample project again
A small scanned room with an IFC model and two saved cuts, to try everything on. It does not count towards the free project.
Offline, no account
Where Always
The app makes no network connections, has no account or sign-in and collects no data. Projects stay on your device.
Projects and files
A new project from scans, models or both
Where Projects gallery › +
Choose one or more files, a folder or a zip. Scans are converted once into an offline project and models are added beside them. Each file stays a scan or model of its own in the project.
Scan formats
Where Gallery › + or Add scans or models…
E57 (with registered setups, colour, intensity and spherical photos), LAS and LAZ 1.0–1.4, COPC, PLY (ASCII and binary), PTS, PTX, XYZ and TXT. For PLY, XYZ and TXT pick the units and the up axis; E57 and LAS carry their own.
Model and plan formats
Where Gallery › + or Add scans or models…
IFC (also zipped or gzipped), USDZ, USD, OBJ, STL, glTF and GLB. A DXF floor plan lies under the scan with its layers. Several model files show together as a federated model, each in its own coordinates.
Add scans or models to a project
Where Menu under the project name › Add scans or models…; in the gallery, … on the project card
More scans are imported into the open project, models are added beside them. Adding to a project does not count as a new project.
Search, sort and select projects
Where Projects gallery, top bar
Search by name; sort newest or oldest first, by name or by size. The selection icon deletes several projects at once.
Rename, delete, show in Finder
Where Gallery › … on a project card (or press and hold / right-click)
Rename a project, delete it (to the Trash on a Mac), or show it in the Finder on a Mac.
Projects elsewhere on the device
Where Gallery, below the projects: Elsewhere on this device and in clouds
.vpc projects opened from elsewhere (iCloud Drive, an external disk) are remembered and open from here. A location can be forgotten.
A project reopens as it was left
Where Automatic
The camera, the cut, the open panels and what was shown are kept with the project and come back when it is opened again.
Moving around
Orbit, pan and zoom on iPad and iPhone
Where In the view
One finger orbits, two fingers pan, a pinch zooms. A tap selects a model element; pressing and holding opens its menu.
Orbit, pan and zoom on a Mac
Where In the view
Mouse: drag to orbit, right-drag or Shift-drag to pan, scroll to zoom. Trackpad: drag to orbit, two fingers to pan, pinch to zoom (⌘ with two fingers zooms too).
Views from the six sides and axonometries
Where Top bar › Views
Top, bottom, front, back, left, right, and axonometries from above and below from each corner. The view is framed on the current cut.
Axonometry or perspective
Where Top bar, first switch
Parallel projection for reading dimensions, or perspective for depth.
Fit to view
Where Top bar › the frame icon; F on a Mac
Frames the whole project, or just what is in the cut.
Walking with the keyboard
Where A Mac, or an iPad with a keyboard
W A S D moves the view, E and Q raise and lower it, the arrow keys look around — as in a first-person game.
Keyboard shortcuts on a Mac
Where Mac
Shift + T, D, F, B, L, R: the sides (top, bottom, front, back, left, right). F: fit. 1, 2, 3: front, side and top views. ⌘[ and ⌘]: smaller and larger points. ⌘⇧D: maximum detail. ⌘⇧G: grid. ⌥⌘D: Display. ⌘N: new project. ⌘⇧W: back to the projects.
Reset view
Where Menu under the project name › Reset view
Brings the camera back to the default view of the whole project.
Scene and the side panel
The side panel
Where The panel icon, top right
Three tabs: Scene (what the project holds), Views (saved cuts) and On this view (measurements and notes).
Hide or show a scan or model
Where Side panel › Scene; top bar › cloud / model
The eye on a row hides the cloud, a single scan, a model or a plan. The row’s menu has Show only this scan or model.
Each scan setup on its own

Each scan in the project can be hidden, shown alone, or given a colour of its own (Colour each scan differently). Hidden scans are not drawn and cannot be measured on.
Properties of a scan, the cloud or a model
Where Side panel › Scene › press a row
Extent, the file’s own data, colour and opacity, and for a model removing it from the project. The original files are never changed.
Model elements by storey, class or file

A DXF plan under the scan
Where Side panel › Scene › Underlays
The plan’s height and rotation, and which of its layers are drawn.
Saved cuts (Views)
Where Side panel › Views
The saved limit boxes and sections. A press switches to one, camera included; a cut can be renamed, updated to the view on screen, or deleted.
Measuring
Distance
Where Tools on the left › Measure › Distance
Two points on the scan or the model. Shows the length with its horizontal and vertical components. Every point is verified against the cloud at full resolution.
Ceiling height
Where Measure › Height
A point on the floor and one on the ceiling; measured straight up, wherever the two are.
Polyline
Where Measure › Polyline
Pick successive points, then Finish. Adds up every segment.
Angle

Snap to corners
Where Measure › Snap to corners
With a model open, points snap to its corners. Measurements always snap to the outline of a cut.
The list of measurements, and a floating one
Where Measure › the list; Floating list of measurements; side panel › On this view
Measurements are kept in the project. They can be renamed, hidden, adjusted by dragging their ends, and deleted — all at once too.
Units
Where Account › Lengths in
Metric (mm, cm, m) and imperial units.
Cutting
Limit box
Where Tools on the left › Cut › New limit box
A box round what you are looking at. Drag its walls to fit a room, the middle to move it, the round grip to turn it. Done, top right, ends editing.
Horizontal slice
Where Cut › Slice
A thin horizontal cut through the whole scan, read from above like a plan. Set its position and thickness.
Room from two corners
Where Cut › Room from two corners
Pick two opposite floor corners; the box is 3 m high.
Exact numbers
Where Cut › Exact numbers
The box’s centre, size and rotation, or the slice’s position and thickness, as numbers.
Save a cut under a name
Where Cut › Save; side panel › Views
The cut is saved with the camera view (Living room, Ground floor, Section A…) to come back to any time.
Filled and hatched cut through the model
Where Cut › Fill the cut; Show outline
Where a cut passes through a solid element, its face is filled and hatched. The outline of the cut is drawn as a line and measurements snap to it.
The active cut
Where The chip under the top bar
Shows which cut is on; edit or remove it from there.
Model elements and selection
Select an element
Where Tap an element; tools on the left › Select (rectangle)
A tap selects one element; the Select tool drags a rectangle over several. On a Mac ⌘-click adds to the selection and Option-drag selects by rectangle.
An element’s menu
Where Press and hold an element; right-click on a Mac
Select, add to the selection, hide the element or every element of its kind, properties, a note here.

Where Element menu › Properties…; selection bar › Properties
Every property set of the element, including what it inherits from its type.
Isolate, hide, look at the selection
Where The selection bar at the bottom
Isolate shows only the selection, with the rest faded if you like. Hide hides it. Look at turns the camera to it.
Colour and opacity of the selection
Where Selection bar › Colour
A colour and opacity of your own for the selected elements; back to the file’s colours any time.
Groups of elements
Where Selection bar › Groups; side panel › Model elements › Groups
A named group from the selection, with its own colour and opacity, to hide, isolate or select.

Notes and BCF
A note on a point
Where Tools on the left › Note; element menu › Add a note here
A note on a point of the scan with text, type (issue, request, clash, remark), status, priority, assignee, due date, labels, a discussion and a picture of the view.
Export notes as BCF
Where Menu under the project name › Export › Notes as BCF…
Each note becomes a BCF topic with the camera view, the picture, the model element and what the view hides.
Import BCF
Where Menu under the project name › Open issues from BCF…
The topics of a BCF file from another tool appear as notes.
All measurements and notes
Where Menu under the project name › Measurements & notes
Every measurement and note, exported as CSV or JSON (with the saved cuts), a snapshot of the view, and JSON import.
Analysis: scan against model
Deviation of the scan from the model
Where Tools on the left › Analysis › Colour the scan by deviation from the model
Every scan point is coloured by its distance to the model — in front, behind, within tolerance. Set the tolerance; Deviation by element lists the elements built out of tolerance.
What the scan shows: built, missing
Where Analysis › What the scan shows…
Tells for each model element whether it is in the scan: built, in part, missing, not scanned. A note can be added to each missing element.
Align the model to the scan
Where Analysis › Align model…
By estimate, by pairs of corners on the model and in the scan, by the georeference, or by dragging grips in the view; fine-tune in steps or let the scan’s points pull the model on (Refine with the scan). The model always moves, never the scan, and its scale never changes. The placement is saved with the project.
Check the model against IDS
Where Analysis › Check model against IDS…
Choose an IDS file. The report shows which specifications elements fail; failing elements can become notes that go out as BCF.
Walls from the scan
Where Analysis › Find walls in the scan
Estimates the floor, the ceiling and the walls from the points and draws them as a plan. Go through the walls one by one, move them in 10 mm steps or throw them out, and export them as IFC.
Display
Colour of the cloud
Where Display (bottom left) › Cloud points › Colour
RGB, intensity, heatmap, elevation, uniform, classification, deviation from the model.
Elevation and a band (floor sag, wall lean)
Where Display › Colour: Elevation › band
Elevation over the whole cloud, or a band of 1–50 cm of your own: fitted to the cloud or the cut, centred on a point, across X or Y or turned (for a leaning wall). Grey outside the band.
Point size, shape, brightness and contrast
Where Display › Cloud points; top bar − / +
Point size, round or square points, brightness and contrast.
Maximum detail
Where Display › Detail › Maximum detail
Shows as many of the scan’s real points as the device can hold, instead of a thinned view. Slower, and the device gets warmer.
Fill the gaps between points
Where Display › Detail
Points far away are drawn larger, so surfaces look solid.
Horizontal grid
Where Display › Show in the view › Horizontal grid
A grid on the floor of the cut or the scan; every fifth line is stronger. The square follows the zoom or is chosen.
Scan setups and panoramas
Where Display › Scan setups; press a marker in the view

Light background
Where Display › Show in the view
A light background instead of the dark one, for pictures in documents.
Performance
Where Display › Advanced
Point budget, target frame rate, adaptive quality, blending detail changes and a performance overlay.
The same display in every project
Where Display › Carry settings between projects
On: every project opens drawn the same way. Off: each keeps its own.

Account and settings
Pro: as many projects as you need
Where Account (bottom left in the projects) › Unlock Pro
One project is free; Pro is a one-time purchase with no subscription. Restore purchase brings it back on another device with the same Apple Account.
Redeem a code
Where Account › Redeem a code
A code for Pro, for example for your feedback.
Feedback
Where The button bottom right in the projects; Account
A questionnaire about working with the app. It goes as an e-mail you send yourself; for a filled-in questionnaire we send a code for Pro. It can be filled in on the web too.
App language
Where Account › Language
Czech or English, whatever the system language.
Status bar on iPad and iPhone
Where Account › Show the status bar
The time and battery are hidden by default, to give the view more room.
What the app does not do
Registering scans
Scans are not registered to each other; an E57 with registered setups opens as it is.
Editing points
Cloud points cannot be deleted, cleaned or classified; a cut only hides them.
Editing models
Models are only read; the IFC file is never changed.
Two coordinate systems into one
Clouds in two different coordinate systems are not brought into one.
Augmented reality (AR)
Neither the model nor the scan is shown over the camera.
Android, Windows, web
The app is for Mac, iPad and iPhone only.
Cloud and sharing in the app
No account or sync; share projects as .vpc files and results as BCF, CSV or LAS.
