  • get_part_dimensions_bolt_pattern_cad

    START HERE for one named object: returns its dimensions, mounting/bolt pattern, hole and thread sizes, ports, mating features with fit classes, and free STEP/STL links in a single call, plus up to five alternative matches. Use it whenever someone designs, prints or buys somethin…

  • find_geometry

    BROWSE: list many matching objects, filtered by keyword, category, group, kind or release year, with paging. Use it when the user wants options or a list ('which M3 screws are there', 'all NEMA motors', '2023 phones', 'free files in Fasteners'), or to find a slug when the name i…

  • find_by_dimensions

    Identify what an object is from one to four sizes you measured (an outline, a bore, a pin, a flange) when you do not know its name; use find_geometry when you do. Each size is compared, within tolerance_mm, against every object's overall size in any order and against its exact f…

  • get_geometry

    FULL RECORD for one object you already have the slug or exact name of (from a search or an alternative): its full sheet and mating features plus the basis of the numbers, every public CAD source with its license, related objects to traverse, FAQ, and paid-pack offers. Use it to…

  • get_free_files

    For importing a real part into CAD, 3D printing it, or modelling a mating bracket or enclosure around it. List the direct download URLs of one object's free STEP and STL files (and DXF where a 2D profile exists), with the license to credit. Use it when files are wanted rather th…

  • get_file_content

    Return the contents of one free file so the geometry can be read or modified directly: STEP and DXF as UTF-8 text, STL as base64. Units are millimetres, true size. Use it after get_free_files gives the file name and the content itself is needed; use get_free_files when a downloa…

  • get_fits

    For designing a part that bolts to, clamps, slides over, presses into or otherwise mates with a real object (bracket holes, bore clearance, boss pocket, shaft fit). Return only the mating features of one object: each hole, pin, pocket, slot or socket that meets another part, wit…

  • list_categories

    Return the whole category tree: every category, the groups inside it, object counts, and the catalog version. Use it to get the exact category and group spellings that find_geometry and find_by_dimensions filter on, or to see how the library is organised; it is the only tool tha…

  • request_object

    File a request for an object that is not in the library so it can be added; it is the only tool here that writes anything. Use it only after find_geometry and find_by_dimensions found nothing suitable; do not use it to ask questions or to request changes to existing objects. Eac…
