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 around. The first thing to understand is what the sketch profile should look like in order to create a revolve.
Take a look at the example below.
If you were to take a quarter section of your completed part, the resultant cross section outline is what the sketch profile for the revolve should look like. This is shown by the red hatched area.
Rules to Follow
There are certain rules that should be followed when creating a revolve.
- A centreline, axis, sketch line or linear edge must be specified as the axis of revolution
- The sketch must not cross the axis
The above shows an acceptable sketch for a revolve. All solid sketch geometry is to one side of the axis/centreline.
The above shows an ‘unacceptable’ sketch for a revolve. The solid sketch geometry exists on both sides of the axis/centreline.
