Does anyone have any good tips or videos when creating a revolve that can pivot on a change angle. The application is I am creating a pipe elbow with a mechanically jointed end and the mechanical joint is a revolve and the axis is tied to the arm that can potentially be at different angles such as a 90 degree elbow, 45 degree elbow, etc... The revolve needs to pivot with the arm of the elbow. Every way I have tried to create this I get errors. If anyone has creating something like this already and knows the 'trick' to get it to work please let me know. Thanks.
