EXPORTGEOJSON

EXPORTGEOJSON writes drawing geometry to a GeoJSON file (.json), for example to use it in a GIS or map program. You choose whether to export the whole drawing or only a selection, and which kinds of objects are included.

Starting

Type EXPORTGEOJSON on the command line, or use the button in the ribbon on the SCAD Data / Export tab, GIS panel.

How it works

1. An Export GeoJSON window opens. Under Source, choose what to export and tick which object types to include (see Options).
2. Click Export. If no type is ticked you get Select at least one entity type. and the window stays open. Cancel ends the command.
3. A save window Export GeoJSON opens. The file name defaults to the drawing name with .json.
4. If you chose Selection, BricsCAD now asks for the objects to export. Select them and confirm with Enter.
5. The command line shows GeoJSON exported: N features to <path>. If nothing usable was found, the command reports No geometry found to export. and no file is written. If you select nothing in Selection mode it says No selection.

Options

Source

Option	What it does
All entities	Default. Exports everything in model space.
Selection	Exports only the objects you select afterwards.

Object types — all types are on by default. The tick box at 3D Entities or 2D Entities switches the whole group on or off at once.

Group	Types	Ends up in the file as
3D Entities	Solid3d, Surface, SubDMesh, PolyFaceMesh, PolygonMesh, Face, Region, Body	Surfaces, split into triangles
2D Entities	Line, Arc, MLine	Line
2D Entities	Polyline, Polyline2d, Polyline3d	Closed: area. Open: line
2D Entities	Circle, Solid, Hatch, Wipeout	Area
2D Entities	Ellipse, Spline	Full ellipse and closed spline: area. Otherwise: line
2D Entities	Point	Point

Each object is written with its layer, object type, colour and opacity.
