At the International Engineering Fair in Brno, we’ll be demonstrating MecAgent – an AI assistant that works directly inside SOLIDWORKS and Inventor. See how a 3D model becomes a manufacturing drawing with dimensions and tolerances, how a description in Czech turns into a macro, and how the AI answers technical questions with source citations.

Bring a part with you (STEP, SLDPRT or IPT). MecAgent generates a manufacturing drawing from it with dimensions, tolerances and GD&T to your chosen ISO or ASME standard. How AI drawing generation works.
Describe the task in Czech or English and MecAgent turns it into a macro directly in CAD – batch exports, drawing preparation, property changes or standards checks.
Mechanical Expert answers questions on standards, calculations and design using verified technical sources – and adds a citation to every answer so you can check it.
MecAgent has passed a SOC 2 audit; in Privacy mode your data is not used to train AI, and Enterprise customers can also deploy MecAgent on-premise. 4CAD is the authorized partner for the Czech Republic and Slovakia.
All demos run in live SOLIDWORKS. You’ll learn the most with your own part – bring a 3D model and we’ll try it together.

An uploaded part becomes a fully dimensioned manufacturing drawing, including tolerances and GD&T to ISO 1101 or ASME Y14.5. Export to PDF and native CAD, linked to the 3D geometry.
Jak funguje AI Drawing
Macro AI turns a text prompt into automation directly in CAD – for example, batch export of sheet metal parts to DXF and PDF. Save the automation and run it with a single click.
Více o MecAgentu
Actions directly in the model from a text prompt, batch renaming of parts and properties, or a 3D part in STEP or STL from a description alone. Features in development (R&D).
Všechny funkce MecAgentuYou’ll find stand 015 in Pavilion F at the Brno Exhibition Centre. The fair is open from Tuesday to Friday: 9:00–17:00 Tuesday to Thursday and 9:00–16:00 on Friday.
The International Engineering Fair takes place on 6–9 October 2026 at the Brno Exhibition Centre. It is open 9:00–17:00 Tuesday to Thursday and 9:00–16:00 on Friday.
In Pavilion F, stand number 015. The nearest public transport stop is Výstaviště – hlavní vstup (main entrance).
All you need is a 3D model of a part in STEP, SLDPRT or IPT format – on a USB stick, for example. We’ll generate a drawing from it and show you how MecAgent could speed up work for your team.
Currently with SOLIDWORKS and Autodesk Inventor. CATIA V5, Fusion 360 and PTC Creo are in development. 4CAD provides licenses, Czech-language support and training.
Let us know in advance when you’re coming and which CAD you work with. We’ll prepare a demo on your type of parts and set aside time for you, so there’s no waiting.
