Highlights

Parts

sw_part_build: a part described as a small JSON recipe (part-ir/1: sketches with rect, polar, grid, steps; extrude, cut, revolve, sweep, fillet, chamfer, Hole Wizard, shell, rib, patterns...) is built, then checked against the expected box, volume or mass, with a hint of what is wrong when it does not match. 40+ single-feature tools too.

Assemblies

sw_assembly_build: the whole assembly in one call - parts, mates by intent (insert, face_to_face, flush, fastener), faces described like the drawing says them (cylinder Ø8, plane normal +Z), generated ISO bolts/washers/nuts, component patterns, coordinate systems found from the drawing's CM values, then mates, interferences, mass and CM are verified. Failures name the suspect mate.

Verification

sw_mass_check, sw_assembly_doctor, sw_interference, sw_collision, sw_part_diff, sw_assembly_diff, sw_answer_sheet (mass and every CM in the units you need).

Drawings

sw_assembly_drawing: views, standard scale, BOM with material and mass, balloons, answer note and PDF in one call; section views through a model point, added automatically for hidden parts; flat-pattern views; title block copied from another drawing.

Reading drawings

sw_drawing_read: from a PDF exported by SolidWorks it finds the views and, for every dimension, the two points of the part it measures; radii, diameters and angles with their centre/vertex; title-block material; scale per view. From a DXF every dimension is exact (definition points x DIMLFAC). Phone photos get enhanced tiles.

Sheet metal

Base flange, edge flange, sketched bend, hem, flatten, flat-pattern DXF/DWG and drawing view.

Exchange

Import STEP / IGES / Parasolid / ACIS (sw_import_model, always from a copy), export STEP, IGES, x_t, STL, PDF, DXF, DWG one by one or in batches, Pack and Go.

Safety

Only files it created or user files opened with an automatic backup are edited; every edit is health-checked and rolled back automatically if it breaks something; saving is blocked after an unverified restore; with sw_exam_ready / sw_instance start the MCP works in its own minimized SolidWorks, separate from the one you are using.
