AI copilot for mechanical design

MecAgent: the AI CAD copilot that automates repetitive CAD work

Type what you need and MecAgent does it in your CAD for you. Parametric parts from a text description, automation of repetitive steps, bulk drawing exports and checks against standards – without writing macros.

How it works

From prompt to finished work in three steps

MecAgent runs as a panel right inside your CAD and works through its API. It takes over routine, time-consuming tasks so designers can focus on real design work. Decisions stay with the engineer.

01

Describe the task

In plain language in the MecAgent panel: “For every sheet metal part, create a drawing with the flat pattern and export it to PDF and DXF.”

02

Let the CAD do the work

MecAgent turns the prompt into CAD operations and macros and runs them itself. You watch the progress right in the model.

03

Save it as a button

Save a successful automation to your buttons and share it with colleagues. Next time it takes a single click.

Text → CAD

Creates a simple, editable parametric part from a description or a sketch.

Example prompt“Flange DN50, 4 × M12 holes on a 125 mm bolt circle.”

Automation

Turns the prompt into a macro via the CAD API, runs it and maintains it.

Example prompt“Add material and mass to the properties of every part in the assembly.”

Drawings and GD&T

Adds PMI/MBD annotations to ASME Y14.5 and ISO; the drawing stays associative with the model.

Example prompt“Dimension the part and add tolerances relative to datums A, B, C.”

Bulk exports

Walks through an assembly or folder and exports drawings and models.

Example prompt“Every sheet metal part: flat pattern on the left, view top right, export to PDF and DXF.”

Search your data

Finds parts and assemblies by keywords or a sketch, even in unorganised folders.

Example prompt“Find the motor bracket we designed last year for line 3.”

Purchased parts

Finds standard and catalogue parts online and inserts them into the model.

Example prompt“Insert a 6205 bearing and ISO 4762 M6×20 screws.”

Compared with manual CAD work

Leave the routine to MecAgent

Manually

  • The same steps again on every part
  • Macros need a programmer and maintenance
  • Exports and renaming take hours

With MecAgent

  • Run the whole sequence with one click
  • Describe the automation in plain language
  • Bulk operations across the whole assembly
Supported CAD. SOLIDWORKS and Autodesk Inventor. CATIA, Fusion 360, NX, Solid Edge, Onshape and Creo are in preparation.
Outputs. Editable parametric parts · drawings in native format · PDF, DXF, STEP · reusable automations.
