Aeronautical design requires precision, accurate geometry, detailed documentation, and the ability to develop both 2D engineering drawings and 3D models. Aircraft components can range from relatively simple brackets and panels to complex aerodynamic surfaces, structural members, engine components, landing-gear parts, and interior assemblies.
xCAD is a general-purpose CAD platform that can support many aeronautical-design workflows through its precision 2D drafting, 3D solid modeling, surface modeling, dimensions, layers, constraints, assemblies/components, visualization, and CAD file interoperability. xCAD describes its products as general-purpose CAD software for drafting, modeling, mechanical engineering, product design, and 3D visualization.
Important: xCAD should be positioned as a general-purpose CAD solution for aeronautical design, rather than as a dedicated aerospace/aircraft engineering suite. Specialized aerospace functions such as aerodynamic CFD, aircraft-load analysis, certified stress analysis, advanced composite simulation, or dedicated aircraft systems engineering may require complementary specialist software.
1. What Is Aeronautical Design?

- Covers
- Panels
- Equipment
A 3D CAD assembly allows designers to examine the relationship between components before manufacturing.
27. Interference and Clearance Checking
One benefit of creating a 3D aircraft component or assembly is the ability to inspect spatial relationships.
Designers can examine:
- Component clearances
- Equipment spacing
- Mounting locations

Array and copy tools can speed up repeated geometry.
29. Pattern and Array Tools
Repeated components are common in aircraft structures.
Arrays can be useful for:
- Rivet locations
- Fastener holes
- Ventilation openings
- Mounting holes
- Repeated brackets
- Structural patterns
Instead of creating each element independently, the designer can establish a pattern and replicate it.
30. Fillets and Chamfers
Edge treatments are important in mechanical and aircraft component design.
Fillet
Creates a rounded transition.
Useful for:
- Removing sharp edges
- Improving transitions
- Refining mechanical components

This workflow is useful for components such as:
- Brackets
- Mounts
- Panels

- Interior components
- Structural concepts
However, composite laminate definition, ply optimization, material analysis, and certification require dedicated composite-engineering and analysis tools.

Visualizing an aircraft component before manufacturing can help designers and customers understand the design.
xCAD supports 3D visualization and product-design workflows.
Rendering can be used to present:
- Aircraft components

- Other CAD platforms
43. Importing Existing Aircraft Geometry
Aeronautical projects often begin with existing CAD geometry.
Imported models can be used as:
- Design references
- Assembly components

For example:
Existing Component → Import → Modify → Add Features → Document
44. 3D Printing Aircraft Prototypes
xCAD can also support prototyping workflows. Its official site identifies 3D-printing tools and formats such as 3MF/STL within its product ecosystem.
This can be useful for producing prototypes of:
- Aircraft brackets
- Fairings
- Interior components
- Mounting concepts
