Survey sheets already name the bridge, the ruin, or the barricade. When a briefing needs that feature as a physical piece on a board, a miniature generator can turn the named object into a mesh with a flat bottom and a scale you can state out loud.

A bridge polyline has a place on the sheet and no underside a printer can grip. The model adds that underside, a wall height, and a footprint, so the feature that was a line becomes an object you can set beside the map. The scale on offer is a tabletop default you lock on purpose, and the base checks tell you the piece can take the plate.

A Map Line Becomes A Physical Piece

A bridge polyline, a ruined footprint, and a barrier line are records. They have a place on the sheet. They do not yet have a bottom, a wall height, or a face that a printer can grip. Turning one of them into a piece means choosing a physical object, a stone bridge, a ruined tower, or a wall, then describing that object so a mesh can be built. The terrain tool is aimed at tabletop scenery, including dungeon walls, ruined towers, stone bridges, trees, and barricades. A GIS desk uses that path when the deliverable is a model on a board: one named feature, one flat-base piece.

Loreform treats each terrain piece as a standalone model: an altar, a chest, a campfire, a portal, or a larger set piece, meant to sit beside figures rather than to tile a coordinate grid. For a site model, that standalone habit is the useful part. One bridge, one ruin, one barrier. You describe the piece, or you upload a reference image of the structure, and the tool returns previews and then an STL for FDM or resin. The sheet keeps the location. The mesh is the object you can put a hand on.

Name The Arch The Wall Or The Barrier

The three moves on the terrain path are plain, and they are how a mapped object gets a body. You pick a type, such as a ruin, a building, a natural feature, or a dungeon piece, and you add the detail that matters, such as a single arch or a broken parapet. The model is generated with a scale and a flat bottom. You download the STL, print it, and place it. The piece is described as a single print, without assembly. Most of these terrain shapes are also described as printable without supports, because the bottoms are flat and the overhangs are kept small. Character files are the ones that ship with supports already built. A bridge with a thin arch is where you look at the arch in the preview, so the flat bottom in that preview is the bottom you print.

“Stone bridge, single arch, flat underside, parapet about the height of a door” gives the model a target it can hit. The type and the detail are what make the proportions do a job, and the flat underside is the instruction that lets the piece share a board with the ruin beside it. Generate from that sentence and the preview has an arch, a parapet, and a bottom. That is the mapped feature becoming a model you can place.

Scale The Piece At The 28mm Default

Terrain pieces come out at 28mm by default. Doors, walls, and furniture are proportioned to that scale, and the published check is whether a door fits a tabletop figure and whether a wall is a believable height beside it. That is a gaming scale, in the same family as the 28mm to 32mm range used for the character models, and it is the control that makes a site piece consistent. You can tell a room what the model is: a bridge, a ruin, or a barrier at 28mm, with openings sized to the figures that will stand next to it. Surveyed elevations stay on the sheet. The board receives a piece whose height you chose by accepting that default.

On Loreform, four concept previews arrive in seconds, and a finished miniature is described as ready in about two minutes, with some full passes taking under five. Use the previews to judge height. The arch of the bridge and the wall you already printed should read as the same scale, because both were generated against 28mm. A door that fits the figures is the default doing its job. A door at the wrong height sits in that same preview, and the next generation puts it back beside the figures at 28mm. A tower that is meant to dwarf them is a different object, and you name it as such in the sentence so the next preview builds that object on purpose. The 28mm proportions are what make the piece a model you can explain.

Doors Walls And Furniture At Tabletop Scale

Hold one question against the preview: what is this piece allowed to stand next to? If the board is a table of 28mm figures, a door that fits those figures is the point of the default, and the wall height is believable because it was proportioned to them. If the board is a site model with no figures, the same 28mm door is still a stated height. You print it as a teaching model of a bridge or a ruin, and you can say the number when someone asks how big the opening is. The tool proportions doors, walls, and furniture to that scale, so the piece is controlled even when the only neighbour on the board is another piece from the same default.

Name the type in the description so the proportions have a job. A single arch and a parapet about the height of a door give the bridge a target the 28mm default can satisfy. The preview then shows whether the arch and the parapet landed together. Generate again from the tighter sentence when you want the parapet changed, and you spend that generation on a piece that can share the board with the ruin beside it. The scale stays the one you can point to.

A Flat Bottom You Can Set On The Board

Flat bottoms are the placement rule, and they are why a mapped object can leave the screen. The terrain pieces are generated so you can set them down and mix them, which is what a board needs when the board is a site model. A flat underside, a broad enough footprint, and a bottom that meets the sheet along a face will sit. The bridge, the ruin, and the barrier can then occupy the places the sheet already named, as objects rather than as another layer in the file.

A miniature maker gives you that mesh and a way to measure it before the plate heats. Base contact is the check for the footprint: enough of the underside touches that the piece can survive printing, not a texture pass. The same checker measures the rest of the print risks and reports dimensions in millimetres. It runs in the browser. The file is not uploaded, there is no sign-in, and it does not spend a credit. Generating the piece does spend an allowance. Checking the file does not. The free check is how you confirm the flat bottom is actually flat, including on a mesh you brought from somewhere else, and it is the control that makes the STL ready to place.

Six Checks That Stay In The Browser

The checker runs six tests, and they are the same family of tests described for every miniature before download. Read them as the proof that the piece is under your control.

• Watertight: no open edges for the slicer to guess across.
• Manifold: every edge shared by exactly two faces.
• Wall thickness: measured against the print height you intend.
• Shells: one body, no floating debris.
• Base contact: enough footprint that the piece can survive the plate.
• Face orientation: nothing inside-out.

A bridge that passes base contact can go on the board with the arch you accepted in the preview. A ruin that passes the shell check is one body, so the print is the tower rather than a cloud of chips. Wall thickness is the quiet control. A parapet that looks fine at thumbnail size shows its millimetre reading on screen, and you can generate a thicker one while the file is still a preview. The slicer then receives a fin that was sized on purpose. Because the check stays on the machine, a survey office can run it on a client file without sending the STL out. The millimetre readout tells you the model’s own size, which is the 28mm piece you are about to set beside the sheet.

Set The Piece Beside The Map Sheet

Loreform fits a desk that wants one physical piece, a bridge or a ruin or a barrier, with a flat bottom and a height locked at the 28mm default. The six checks confirm watertight mesh, a single shell, a readable wall, and a base that can take the plate. The sheet still holds the name and the place. The model is what you put down on that place.

Describe one feature, accept a preview whose door or arch matches the 28mm figures it will stand beside, and run the six checks before the print. Then set the piece beside the map sheet. A flat base and a stated scale are why that bridge, ruin, or barricade can leave the polyline and sit on the board as a model you can pick up.
