Export the site in 3D — CivilCraft help

The 3D view exports what it shows as a 3D model another program can open: a 3D viewer, a modeler, a game engine or a visualization tool.

Export

Open the 3D view (DD) and choose what shows with Show. What is hidden is not exported.
Click GLB or OBJ on the bar. The file downloads as "project name-3d.glb" or "-3d.obj", and the status bar says the origin.

	GLB	OBJ
Surfaces	Meshes with normals and the band or surface colours	Meshes with normals (no colours)
Pipes and structures	Round meshes, problem ones in red	Round meshes
Contours, breaklines, alignments, ticks, corridor and pad lines	Lines, each set in its colour	Line records (`l`)
Survey points	Points	Point records (`p`)

Each set keeps its name ("Existing ground", "Pipes", "Major contours" and so on), so you can hide or style it in the other program.

Meters. A feet project is converted from US survey feet (1 ft = 1200/3937 m).
Y up, the usual convention for these formats: easting becomes +X, elevation +Y, and northing −Z.
True scale. The vertical exaggeration of the view is not applied.
A local origin. State plane coordinates are millions of feet, too large for the single-precision numbers these formats store, so the file is written relative to a nearby origin: the existing ground's own origin for easting and northing, and its lowest elevation rounded down. The origin, in project units, is recorded in the file: in a GLB as extras on the scene and its top node, in an OBJ as a comment line near the top (# origin easting … northing … elevation …). To place the model back in project coordinates, add the origin (after converting meters back to feet on a feet project).

Exporting the exaggerated view, or exporting in project units instead of meters.
Textures, a material file for OBJ (.mtl) and per-object properties (names of pipes and structures are only in CivilCraft).
Exporting the corridor as separate solids, or the profile view in 3D.
