Profile
The profile is defined by a set of nodes selected by the user.
The shape of the face is defined by a polygon using the selected nodes in a sequence.
This feature allows the sweeping of the profile.
Once a profile is created, it can be saved and imported for latter use.
Bolts, liners, valve seats can be defined using a profile and stored.

Profile
Using the Start / End / Restart buttons, select a set of nodes.
Specify the angle of revolution and the axis about which the profile is to revolve.
Enter the number of elements and the mesh size.
