Before finalizing a design, it can be smart to take a final look at your pipe segments, pipe cuts, and welds. You may be able to optimize manufacturing costs by reducing the number of pipe cuts.
To make the process easier, Creo includes the Remove Pipe Segment tool. This feature allows you to easily investigate alternative routing paths to minimize the number of pipes and subsequent cutting and welding operations.
