Autodesk Alias is often used for design and styling in the automotive, marine, aircraft, sporting equipment, electronic enclosure, children's toy, and fashion accessory markets. Alias .wire data reads directly into Autodesk Inventor, Showcase and 3DsMax and It exports into several other 3D engineering packages via IGES or STEP such as SolidWorks, Pro/ENGINEER, CATIA, and Unigraphics. The program has two types of modelers within it: NURBS and polygons. As the product is sold specifically as CAID rather than CAD, its tools and abilities are oriented more towards the "styling" aspect of design - that is to say, the product's housing and outer appearance. It does not go into mechanical detail to anywhere near the extent that CAD programs such as Catia, Siemens NX, Inventor, Pro/ENGINEER and SolidWorks do, but has a much more powerful set of tools for the creation of precisely sculpted curves and surfaces.
