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.
