Adding sections

Print a larger area in sections, or more sections around a print made before.

A model larger than the bed prints in sections, each on a plate of its own. Sections, under Area, adds a row or a column of them to the area. For a model printed before, From a print's file makes new sections that meet the print along their edges.

Sections of an area

Open Sections, under Area. It says how many sections the model prints in and has a small picture of them, as they lie on the map. The map shows the lines between them on the area.
The two buttons on each side of the picture take a row or a column of sections off that side of the map, or add one there.
Generate and download. The whole model is made as one, so its sections fit together, and each is a plate of its own.

Each press makes the area one section larger and leaves the scale as it is. It turns on Multi-plate export and sets the section size under Export to the size the sections have, so they stay that size. Sections can be added to rectangular and rounded areas. A circle or a hexagon keeps its proportions, so it has no rows or columns to add: it is still cut into sections to fit the bed, and a larger Scale under Size prints it larger, in more of them.

Sections around a print

Once part of a model is printed, a larger model of the area isn't the same along the print's edges, so its sections wouldn't meet the print. Sections added from the print's file are made to meet it. Files downloaded since November 2026 carry what that takes, unless Include settings was off under Export.

Under Area, open Sections, press From a print's file, and choose the 3MF or .glb downloaded for the print. A file dropped on the page or opened with Load settings works too: Area then offers Add sections.
Choose the sections to add, in the grid under Area or on the map. The printed ones are grey, the new ones blue, and the ones around them that can be added are dashed. The grid lies as the map does, north up. Row above, Row below, Column left, and Column right add a whole row or column along that side, and All around adds a ring of sections around everything printed and chosen. The whole model can span up to 64 rows and 64 columns.
Generate. Only the new sections are made, and the 3D view shows where the rest is beside them.
Download. Each new section is a plate of its own, named by its row and column in the whole model, counted from its top left.
To go on, press Add more around these: the sections just made count as printed, and the next ones meet them too.

What stays the same

New sections keep the print's scale, its terrain grid and the height its terrain is measured from, and its underside, so they stand level with it. Where they meet it, they take the print's heights along its edge: the terrain's, a lake's or river's, how low a building crossing it stands, and a bridge deck's. Roads, paths, and railways crossing the edge are laid as the print laid them there. Every file numbers the filaments the same, so the slicer's color slots stay as they were.

New sections read the same map data the print was made from, while it's still available: about two months after the print. After that they read the newest, and the model's warnings say so.

The settings and colors are the print's too. Change one and Area says what changed since the print, with Use the print's settings to put them back. New sections only meet the print where they're made the same way.

A file downloaded for new sections can have more added in turn: it carries everything printed so far.

Where the ground in the new sections is lower than the print's lowest point, their base gets thinner, down to 0.6 mm. Lower still, they get a lower underside, and the download says by how much: put that much under the printed sections, a flat board or a plain printed plate, so their tops line up.

Known limits

Only prints of rectangular map models without a border rim can have sections added from their file. Prints of LiDAR only models can't yet.
Files downloaded before November 2026 don't say how to line new sections up. Load one, generate it, download it again, and add sections to that file.
Map data updated since the print, read once the print's is no longer available, can show along the edge: a road, building, or body of water mapped differently since may not meet it. So can elevation data updated since.
Trees keep clear of the edge on both sides, so a narrow strip without trees runs along it.
Small water touching the edge, a pier or breakwater narrower than a millimeter, and two bodies of water the print kept apart that the new sections join, can differ by a fraction of a millimeter there.
A road or railway running almost along the edge can come out on one side of it only, for a few millimeters.
Terrain brush strokes and added shapes that cross the edge are made again in the new sections from what lies on their side of it, so they can meet the print with a step: a flattened or smoothed patch by a few tenths of a millimeter, a flat-topped shape by the slope under it. Keep them clear of the edge where sections will be added. Area says when some cross it.
A bridge that stood high at the print's edge but comes down to the road soon after it, in the new sections, comes down more steeply than Maximum grade where that's the only way to meet both. The model's warnings say so when it's more than twice as steep.
With LiDAR buildings, a building crossing the edge has its roof measured again for the new sections, which can differ a little from the print, more so where another survey covers them.
Routes in the file reach only a little past the print. Import a route again to carry it on into the new sections.
Downloading new sections requires the tier with Multi-plate export, since they're part of a model on several plates.
