An AI assistant for Inventor, NX, Solid Edge and AutoCAD. You describe the job in plain English; it runs real operations in your CAD system and reports what it measured. The AI is your own, and from version 1.3.0 your conversation goes straight from your PC to it: what goes where.
The functions people ask about most, with the CAD systems each one has been measured working in. What each licence includes is on the pricing page.
Reports and manuals written by the product itself - no office software needed on the PC.
Ask for a report and get a real .docx, .pdf or .xlsx file with your tables, properties and pictures of the model, made by the product's own document writer.

Give it a BOM spreadsheet and the parts it lists are inserted into the assembly, row by row.
Available for Inventor NX Solid Edge
Start from what you have: an old drawing, a picture, a scan mesh or a solid with no history.
Point it at a DXF or DWG, a vector PDF or a picture of a dimensioned drawing. The printed dimensions set the size, and the reply compares the volume it expected with what was built.
Available for Inventor NX Solid Edge
Bring a scan or a 3D-print mesh into the model as a body, with its volume and size read back on arrival.
Available for Inventor NX Solid Edge
An imported solid with no history is rebuilt as ordinary, editable features and checked against the original's volume. Works best on machined and sheet-metal parts; complex castings are not rebuilt fully yet.
Available for Inventor NX Solid Edge
Open a saved model and give it a reference drawing - PDF, picture, DWG or DXF. The new drawing gets matching views at the reference's scale and layout.

A study set up by chat, solved, and its numbers read from the solver's own output.
Say what the part is made of, which face is held and what pushes on it. The study is meshed and solved, the load in the solver's input is checked against what you asked for before the solve, and displacement, stress and factor of safety are read from the solver's own result file.
Available for Inventor
Describe the part the way you would to a colleague. SphereHarness drives your CAD system's own features, then reads the geometry back so you can check what was built rather than take a success message on trust. You remain the engineer of record, and the measurements are there to make checking quick.
Sketches, extrudes and cuts, revolves, sweeps, lofts, holes and threads, fillets, chamfers, shells, drafts, patterns and mirrors are built with your CAD system's own features, so the result has an ordinary tree you can edit. To change a value later, name the feature and say what should change - no delete and rebuild.
Try Create a 120 x 80 x 15 mm plate, add four Ø9 mm through holes 15 mm in from each corner, then tell me the volume and bounding box
Covers Inventor NX Solid Edge
Replies carry numbers measured by the CAD system: volume, bounding box, where a sketch plane really landed, and per-edge evidence for every fillet. A cut that removed nothing shows up as a zero volume change, and a fillet point that matches no edge is refused with the nearest real edges named.
Try Add an R8 fillet to the four cut-end edges at these world midpoints, and report the per-edge evidence and the volume change
Covers Inventor NX Solid Edge
Base flanges, edge and contour flanges, hems, jogs and corner breaks, then the flat pattern and a DXF for the laser. The flat patterns of a whole folder of parts can be nested onto stock sheets.
Try Create a new sheet metal part with a 200 x 120 mm base flange, 2 mm thick, add a 40 mm edge flange along the long front edge, and export the flat pattern to DXF
Covers Inventor NX Solid Edge
Offset, extend, trim and thicken surfaces, and extrude or revolve an open profile as a surface instead of a solid. Give a spline as a NURBS - control poles, degree and knots - and each CAD system builds the same curve, instead of interpolating fit points its own way.
Try Create a spline from these control poles as a NURBS: degree 3, clamped knots [0,0,0,0,1,1,1,1], poles [[0,0],[30,60],[60,-20],[90,40]]
Covers Inventor NX Solid Edge AutoCAD
List, create and change named parameters and equations with each CAD system's own mechanism. Assign a material and get the mass, set colours and transparency, and fill in custom properties.
Try Create a parameter "Thickness" set to 15 mm, drive the extrusion depth from it, then assign 6061-T6 aluminium and tell me the mass
Covers Inventor NX Solid Edge
Point it at a dimensioned drawing - DXF, DWG, a vector PDF or a scan - and the printed dimensions set the scale; the reply compares the volume it expected with what the CAD built. A photo gives a proportional model scaled from one dimension you supply, and it is labelled as exactly that. STL and OBJ meshes import as a solid or as a mesh body.
Try Build a part from C:\ref\bracket.pdf and tell me the expected and the measured volume
Covers Inventor NX Solid Edge
Score a part against machining, sheet-metal, injection-moulding, casting, 3D-printing or welding rules, and get a Word report with screenshots. Draft analysis, parting lines and core and cavity splits are available too, with the differences between CAD systems stated rather than hidden.
Try Run a DFM analysis on this part for machining and tell me what fails
Covers Inventor NX Solid Edge
Place components, mate them by name, and produce the drawing - with the solver status, the dimension values and the sheet layout checked for you.
Insert and position components, then ask for a mate by component name - the matching faces are found from the geometry. Every mate is checked against the assembly solver, and one that does not come back healthy is removed and reported rather than left in the tree looking finished.
Try Insert the pin at (0, 0, 18), make it concentric with the fork, and report the solver status and both bound faces' radii
Covers Inventor NX Solid Edge
Export a bill of materials in four shapes - all levels, parts only, top level or indented - or build an assembly from a BOM spreadsheet. Check interference, make exploded views, switch between each CAD system's own variants, and clone a whole product structure with a rename rule.
Try Export a parts-only BOM with description, part number, material and revision columns to C:\reports\parts.xlsx
Covers Inventor NX Solid Edge
Ask for a sheet with views and they are laid out so they neither overlap nor run off the sheet. When the expected value of a dimension is known, the created dimension is read back and one that does not match is removed. Notes, balloons, BOM tables, centre marks, GD&T, weld and surface-finish symbols are all available, and PDF, DXF and DWG export.
Try Create an A3 drawing of this part with front, top and right views and dimension every feature
Covers Inventor NX Solid Edge
Hide and show components, bodies and reference planes without deleting or suppressing anything. Each change is read back entity by entity, so the reply counts what really changed, not what was attempted.
Try Hide every component except the pin
Covers Inventor NX Solid Edge
Lines, arcs, blocks, xrefs, layers, annotation and drafting symbols, layouts and plotting, always in millimetres. AutoCAD is not a feature-based modeller, so a request for a solid is refused by name rather than approximated.
Try Create a layer called DIMS, colour 3, linetype CONTINUOUS, and make it current
Covers AutoCAD
Move a design between CAD systems with its history, or give an imported solid a history it never had.
Extract a part's history to a plain JSON file in one CAD system and rebuild it feature by feature in another, so the target has real sketches and features you can edit - not the single dumb solid a STEP file gives you. The rebuild report lists every operation's outcome, and you compare volume and bounding box against the source.
Try Recreate the part from C:\transfer\bracket_tree.json and save it as C:\transfer\bracket_copy
Covers Inventor NX Solid Edge
Imported a STEP or Parasolid file with no history? Refeature Solid analyses the solid and rebuilds a feature tree - extrudes, revolves, fillets, chamfers, holes and patterns - and checks the result against the original's volume, bounding box and hole count. A rebuild that does not match is reported as a mismatch, not as a success.
Try Recognise the features on this solid and rebuild them

A family of sizes from one master, and dimensions driven towards a target - each result measured, not assumed.
Capture the values that drive a design - dimensions, parameters, properties, feature suppression, material - and fill in a grid of named instances. Generate writes each instance, reads every value back, saves it as its own file and puts the master back; an instance whose values do not hold is named and not saved.
Try Capture a variation template called "Bracket" from this part, including dimensions, parameters, properties and material
Covers Inventor NX Solid Edge AutoCAD
Declare which dimensions may change, the limits and the goal, and the study runs: AI-driven, full factorial, Latin hypercube, gradient descent, NSGA-II for several objectives, the CAD system's own design of experiments, or topology optimisation. You apply the winner deliberately, then re-measure.
Try Make the rib thickness a design variable between 4 and 12 mm, keep von Mises stress under 180 MPa, and minimise mass

Set up, solve and report a study by chat, inside your CAD system's own simulation environment.
Say what the part is made of, what is held and what pushes on it. The study is created in the CAD system's own simulation environment, meshed and solved, and you get displacement, stress, factor of safety and reaction force. Faces are picked by geometry - the minX face, the largest face - and each pick is reported with its area and normal, so you can check the setup before you believe the result.
Try Run a linear static stress analysis on this steel bracket: fix the minX face and apply 300 N in -Z on the maxX face. Report displacement and von Mises stress.

Work with the data-management system your CAD is already connected to - no second sign-in, and every rule of your vault still applies.
When NX runs in Teamcenter managed mode, parts are items and revisions. Create a part as the item type you name, attach a dataset as Master, Specification, Manifestation or Altrep, save as a new item, and list an item's datasets and relations. Clone whole assemblies out of or into Teamcenter from an Excel plan - dry run first, then a report of what each part became, read back rather than assumed.
Try Export assembly 000123/A from Teamcenter to D:\work\clone using D:\work\clone-plan.xlsx - dry run first

Check files in and out, search the vault, read and update properties - with a dry run for bulk changes - move files through lifecycle states, revise them, attach them to change orders and export the vault BOM. It uses the vault connection Inventor already has and never asks for a password in the chat.

Run the scripts your team already has, record the jobs you repeat, and replay them without paying for an AI conversation each time.
Import macros, rules, journals and compiled .NET assemblies into the Automation Hub once, and anyone can run them by name with parameters. Importing never runs anything. Every run is judged by reading the document before and after, so a script that returned cleanly but changed nothing is reported as exactly that.
Try Import every script in C:\team\scripts into the Automation Hub
Covers Inventor NX Solid Edge AutoCAD
Record a job while you do it; the recorder keeps only the steps that finally worked and offers parameters. Run it over a folder of parts or the rows of a spreadsheet as one approved operation. A macro run calls no AI model, so the ninetieth part costs no more tokens than the first: none.
Try Run the "Enlarge holes in a folder" macro on C:\Projects\Frame with delta 2

A design-rule corpus ships with the product: 1,076 machine-checkable rules across thirteen engineering domains. Ask whether a dimension is allowed and the answer names the rule, what it requires, the failure mode, the remedy and the standard it comes from. A rule whose inputs you have not given reports that it could not be evaluated - it never passes quietly.
