ACAD is a full featured 3D wireframe, surface and solid modeling package with many design and analysis capabilities specifically tailored for aircraft design.
The system is capable of modeling highly complex surfaces. Its geometry engine is based on cubic Rational B-Splines. The hybrid B-Rep and CSG facetted solid modeling engine is fully integrated with the surfacing package. The surface mesher provides a high degree of control over mesh quality and density. ACAD's meshes are used extensively for CFD and RCS analysis.
ACAD offers a wide variety of tools for interfacing with other CAD and analysis packages. Output formats include IGES, Nastran, Patran, STL and a facet fileformat that has been adopted by the EMCC.
