create_voxel_model
Create voxel model
Create an editable VoxelDraft model from compact commands. Returns a short modelRef for later plugin calls and does not save to Cloud Projects. Use VoxelDraft's compact instruction stream instead of emitting one JSON object per voxel. Coordinates are integers 0..63. Colors are either #RRGGBB or a zero-based palette index. Commands: ["box",x1,y1,z1,x2,y2,z2,color,hollow?] ["ellipsoid",cx,cy,cz,rx,ry,rz,color,hollow?] ["cylinder","x"|"y"|"z",x,y,z,radius,height,color,hollow?] ["line",x1,y1,z1,x2,y2,z2,color] ["roof","x"|"z",x1,y1,z1,x2,y2,z2,color] (gable roof, axis is ridge direction) ["runs","x"|"y"|"z",color,[[x,y,z,length],...]] (preferred exact/freeform representation) ["points",color,[[x,y,z],...]] (sparse details only) ["erase",x1,y1,z1,x2,y2,z2] ["recolor",fromColor,toColor] ["copy",x1,y1,z1,x2,y2,z2,dx,dy,dz] ["repeat",x1,y1,z1,x2,y2,z2,dx,dy,dz,count] ["mirror","x"|"y"|"z",plane,x1,y1,z1,x2,y2,z2] (plane is a grid boundary 0..64) Prefer box/roof/ellipsoid/cylinder for bulk geometry, runs for irregular silhouettes, repeat/mirror for repeated or symmetric parts, and points only for small details. This usually uses far fewer model tokens than raw voxel JSON.

edit_voxel_model
Edit voxel model
Edit the temporary model identified by modelRef and return a new modelRef. This does not modify a saved cloud project. Use VoxelDraft's compact instruction stream instead of emitting one JSON object per voxel. Coordinates are integers 0..63. Colors are either #RRGGBB or a zero-based palette index.

Load a VoxelDraft project
Load one private Cloud Project and return a short modelRef for later plugin calls. Requires project-read OAuth scope.

render_voxel_model
Render voxel model
Preview a VoxelDraft modelRef. ChatGPT can render an interactive Three.js/WebGL widget; everyone also receives an interactive WebGL URL. Signed-in VoxelDraft Plus users may additionally receive a cached PNG when includeImage is true.
