You can define the model’s geometry quickly if there is a CAD file (with .dwg or .dxf filename extension) available to use as a background. You trace the CAD drawing with object tools to facilitate the finite element mesh generation. You can also use the CAD drawing to locate other objects such as loads. Snap tools make tracing the imported CAD drawing easier.

It is not necessary, however, to use a CAD file. If the floor is straightforward, or there is no drawing available, you should skip this chapter. For strip-like models that do not warrant the use of a CAD file, it may be better to use Strip Wizard.
