Creating revolves in SOLIDWORKS can be achieved in a few simple steps. This article discusses what geometry is required to create a revolve as well as how to visualise the required sketch profile. In order to create a revolve in SOLIDWORKS, you need a sketch from which the revolve can be created as well as an axis for this sketch to be revolved ... right click on cut-plots and select insert. Select the front plane as reference, and leave the default display choice of contours. Under contours, select velocity (x) and slide the slider all the way to the right for maximum steps between the minimum and maximum velocity.
Probably there is a method to get by using Solidworks.I will work on 3D modelled human leg, I want to get centerline of it to use in analysis as reference. It depends on which plane you are working in. Once you understand the concept of planes it will be easy to draw the centreline.
