  • specs

    uCAD's script language at spec version cae9943a0a: a small Python, with every function, its arguments and the objects it returns, the rules, how this service works, the reference examples and what is new. Needed to write a script for run_script; the language changes, and this is…

  • 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.

  • 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 picture…

  • view

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

  • 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.

  • share

    A link to a drawing that anyone can open, with no uCAD account: they see the drawing as it is now (and as it changes later) in uCAD, and can turn it around, measure it, cut sections, download it and edit a copy of their own; its script goes with it. Use it when the user wants to…

  • drawings

    The drawings kept in the user's uCAD account, newest first: id, name, when changed, link (and the link anyone can open, for those shared).
