Autodesk Inventor

Project a body's edges onto the sketch — exact lines, arcs, circles and splines, linked to the model. Use it to build on existing or reference geometry (e.g. remodelling an imported part) instead of re-tracing curves point by point. Args: face_index: Project every edge of this face of the body (find_faces). edge_indices: Or these edges, "3,7,8" (find_edges). body_index: Body in a multi-body part (1 = first). sketch_index: Sketch number (0 = latest sketch).

Hot-reload inventor_api.py from disk. Use after editing the wrapper — no Claude Code restart needed. Keeps the COM connections; clears this Inventor's execute_python namespace.

Revolve a sketch profile around a work axis to create or cut 3D geometry. PREFERRED workflow — no construction line needed in sketch: 1. create_sketch("XY") 2. draw_closed_profile([[0,0],[30,0],[30,8],[15,60],[0,60]]) ← profile only 3. revolve(axis="Y", operation="join") For a revolve CUT (e.g. groove): 1. create_sketch("XY") 2. draw_closed_profile([[8,26],[15,26],[15,34],[8,34]]) ← groove cross-section 3. revolve(axis="Y", operation="cut") Profile must be on one side of the axis (all X ≥ 0 when axis="Y"). Args: angle: Revolution angle in degrees (360 = full revolution, default). axis: Rotation axis — "X", "Y", or "Z". Default "Y" for lathe parts on XY plane. sketch_index: Sketch number (0 = latest sketch). operation: Boolean operation — join (add material), cut (remove), intersect, or new.

Save the active document — never opens a dialog, and never writes a library or Content Center file. Dependents that changed (e.g. sub-assemblies, edited parts) are saved one by one first, except files in the project's library paths or Content Center folders and Content Center members: Inventor marks standard parts dirty after opening an old assembly, and re-saving them would rewrite shared library files. Returns the files saved and the ones skipped. The path is checked first (characters, extension, an existing file) so a bad one gets a clear message instead of Inventor's E_INVALIDARG. Args: path: Full file path to save as (e.g. "D:/parts/flange.ipt"). If empty, saves in place. overwrite: Replace a file that already exists at path (not one open in Inventor). save_dependents: False = save only this document (Save2(False)); changed dependents stay unsaved and are listed.

Cut through a sheet metal panel — depth follows the thickness, so it stays parametric. Checks that material was removed (a cut sketched on a work plane silently removes nothing). From a sketch on the panel face: one sketch with several closed shapes = several holes. Or at WORLD coordinates, with no sketch axes to think about: face_index + circles / rectangles. Args: sketch_index: Sketch number (0 = latest). face_index: Face of the sheet (find_faces), for circles / rectangles. circles: [[x, y, z, diameter], ...], e.g. [[180, 267, 0, 4.9]]. rectangles: Lists of 4 corners, [[[x,y,z], [x,y,z], [x,y,z], [x,y,z]], ...].

Rotate occurrences about an axis in steps and report collisions at each angle — e.g. check a door opens 0–110° on its hinge axis without hitting the body, or a lock tongue turns freely. Positions are restored afterwards. Args: moving: Comma-separated occurrences that rotate together (door + lock + door studs). axis_point: A point on the axis, "x,y,z" in mm (e.g. the hinge pin). axis_dir: Axis direction, e.g. "0,1,0". start / stop / step: Angles in degrees. against: Occurrences to test; empty = everything else. measure_to: Optional occurrence to report the minimum distance to at each angle.

Wrap multiple operations in one undo unit with rollback. Args: action: "begin" before a risky multi-step build, then "commit" on success or "abort" to roll back EVERYTHING since begin in one step. name: label shown in Inventor's undo list.

Browse the Content Center and make member parts to place (place_components / place_components). Step by step — each call is quick (the whole tree takes minutes to walk, so give a path): content_center() → top categories content_center("Structural Shapes") → sub-categories content_center("Structural Shapes/Channels") → families content_center("Structural Shapes/Channels", "DIN 1026-1") → sizes content_center("Structural Shapes/Channels", "DIN 1026-1", "U 100", length=1500) → part file path Args: category: Category path, "/"-separated, as listed. family: Family name, as listed. size: Size designation as listed (spaces and case ignored). length: mm — a custom-length member (structural shapes). 0 = standard member. file_name: Where a custom member is saved (default: project workspace / Content Center Custom/<family> <size> L<length>.ipt).
