Input schema (JSON)

{
  "type": "object",
  "properties": {}
}

example

The script of one of the reference examples listed by specs (by its id): a finished model built carefully in uCAD's language, to learn from before building something like it.

read-only

Argument	Type	Description
id*	string

      "type": "string"
    }
  }
}

run_script

Run a whole uCAD script on a drawing in the user's account (a new drawing when `drawing` is left out) and keep the result there. Returns the report (every solid with its size and place, warnings, print() output, or the error with its line), the drawing's id and link, and pictures of it. Each run replaces what the drawing's previous run made. The language is at spec version e69d2ae9e0: if what you know of it is another version (or none), call specs first.

Argument	Type	Description
code*	string	The whole script (uCAD's Python, see specs)
name	string	A name for a new drawing (as the user sees it in Open)
views	array	The sides to show it from (one picture each): iso, iso_back, front, back, left, right, top, bottom. Default: iso.
width	integer	Picture width in pixels (default 800)
height	integer	Picture height in pixels (default 600)
drawing	string	The id of the drawing to run it on. Left out: a new drawing.
spec_version	string	The spec version (from specs) the script is written for. Now: e69d2ae9e0

scene

What is in a drawing now: its solids and objects with sizes and places, flat shapes drawn by hand, and its script with line numbers.

read-only

Argument	Type	Description
drawing	string	The drawing's id (from an earlier run_script, or from drawings). Left out: the drawing worked on last.

Input schema (JSON)

{
  "type": "object",

      "description": "The drawing's id (from an earlier run_script, or from drawings). Left out: the drawing worked on last."
    }
  }
}

specs

Call this FIRST in every session, before writing any uCAD script, even if you have notes or a skill about uCAD from before: the language (a small Python: every function, its arguments and the objects it returns, with the rules), how this service works, the reference examples, what is new. The language is at spec version e69d2ae9e0 now; a copy with another version is out of date.

read-only

No arguments.

Input schema (JSON)

{
  "type": "object",
  "properties": {}
}

view

Pictures of a drawing as it is now (with anything the user changed by hand), from the sides asked for.

read-only

Argument	Type	Description
views	array	The sides to show it from (one picture each): iso, iso_back, front, back, left, right, top, bottom. Default: iso.
width	integer	Picture width in pixels (default 800)
height	integer	Picture height in pixels (default 600)
drawing	string	The drawing's id (from an earlier run_script, or from drawings). Left out: the drawing worked on last.
