Build a thing in the 3D builder from steps, and link it

Builds anything (a character, an animal, a car, a house) in Jabbertoon's 3D builder from steps, as its buttons do: spine, grow, bone (a skeleton, a bone at a time), add a ready part (leg, arm, head, wing, wheel, hat ...), set, copy, remove, look. Checks every step, says what was made (its parts and size) and gives a jabbertoon.com/editor/ link that opens it in the Studio, to change and use in a cartoon, world or game. Over MCP the answer also shows a picture of it from four sides. Steps that start {"op": "new", "kind": "move"} make a move from keys, {"op": "new", "kind": "world"} a world (a level is played to check it), and kind "game" a game seen from the side, from above or in space, or "trench", "space", "surface" or "sky" a game with depth to fly, "walk" a place to walk at real size (played on foot: told what cannot be reached). A refused step says where, why and how to fix it. export_link opens Export, free: STL/3MF to 3D print, glTF (Blender, Unity, Godot), SVG, Minecraft .schem. The steps: get_guide {"topic": "build"}, a game's {"topic": "game"}.
