You find here a step by step video series about using MFis Wire for modelling your wire bond layouts in 3D. It starts with importing a geometry of an example power module. You learn the basics for sketching and using object snaps. Creating a bond wire layout is explained on an example and a 2D drawing is derived.
1. Importing and Preparing Geometry
After a quick intro to the Rhino user interface, a geometry is imported and organized in layers. Methods for selecting objects are presented.
