Variational Sweep in NX is a tool that has improved over time and is, to date, a very powerful tool in many situations - including those areas which have been overlooked where traditional modeling techniques are utilized.
The following demonstrates a small sample of the powerful functionality contained in Variational Sweep:
Multiple Section Strings as well as Individual Section Strings in a multiple cross section string defined sketch
The command supports a wide range of workflows while designing various complex system of parts where the sectional interpart relationship needs to be specifically controlled and maintained, such as a vehicle door to bodyside system of parts.
Have a look at the video below to follow the process steps of the multi-step workflow of sculpting a multiple interpart rocker area.
