Mechanical Design & 3D CAD
Precision Engineering Design
Our mechanical design services bridge the gap between creative concepts and physical reality. Using industry-standard Fusion 360 software, we create robust, fully parametric 3D models that capture your design intent while maintaining the flexibility for future iterations.
We don't just "draw" parts; we engineer them. Every component is designed with its function, material properties, and manufacturing method in mind. Whether you need a complex mechanism, a consumer product enclosure, or a rugged industrial fixture, we deliver production-ready data you can trust.
Core Capabilities
- Parametric 3D Modeling: Intelligent models that update automatically when dimensions change.
- Assembly Design: Large-scale assemblies with interference detection and motion analysis.
- Technical Documentation: Comprehensive 2D drawings (ISO/ASME) with full geometric dimensioning and tolerancing (GD&T).
- Simulation (FEA): Stress, strain, and thermal analysis to validate performance before prototyping.
- Rendering: High-quality visualizations for marketing and stakeholder presentations.
Specialized Visualization
For high-end architectural rendering and advanced marketing visuals, we partner with IAVisual to bring your products to life in photorealistic environments.
Mechanical Design Deliverables
A mechanical design package can include the files and documentation needed for engineering review, prototype builds, supplier quoting, and production release.
3D CAD Package
Native Fusion 360 parts and assemblies, STEP or IGES exports (they open in SolidWorks), STL or 3MF prototype files, and organized revision folders.
Manufacturing Drawings
2D drawings with dimensions, tolerances, materials, finishes, notes, critical dimensions, and supplier-facing manufacturing information.
Engineering Notes
Design assumptions, material rationale, tolerance strategy, prototype recommendations, and open risks to validate before production.
What We Design
IAEngineering supports mechanical design work for products and subsystems where form, fit, function, material selection, and manufacturing route need to be considered together.
Product Enclosures
Plastic and metal housings for electronics, sensors, tools, fixtures, handheld products, and industrial devices.
Mechanisms and Assemblies
Moving parts, brackets, mounts, pivots, fastening strategy, clearance checks, and assembly sequencing.
Production Parts
Machined, molded, printed, cast, or sheet metal parts designed with the target process in mind from the beginning.

Mechanical Design FAQ
Can you work from sketches?
Yes. A sketch, rough model, photo, requirements list, or existing prototype can be enough to begin concept development.
Do you provide production drawings?
Yes. Drawings can include dimensions, tolerances, materials, finish requirements, GD&T, and supplier notes.
Can you improve an existing design?
Yes. We can review existing CAD for manufacturability, strength, assembly, tolerances, or supplier feedback, then update the model and drawings.
See the engineering communication, not just the service list
Ignas Anskaitis, IAEngineering’s founder and principal engineer, publishes the following visuals in his personal portfolio. They are portfolio visuals, not a claim of a completed IAEngineering client project, tested performance or production approval.
Internal layout: feeder mechanism and enclosure
Public portfolio visualization of an internal product layout. Useful for discussing component fit, assembly access and the interfaces a CAD brief must define.
Exploded assembly communication
Public portfolio visualization showing separated assembly components. Useful for discussing assembly order and the information needed in a supplier-facing documentation package.
For your project, the paid scope can specify native CAD, STEP exports, manufacturing drawings, revision notes and an assembly BOM. Those deliverables are not included in the free initial review.
