In this myPIPE tutorial, “How to Use Part Nesting in myPIPE,” we walk through the Nesting feature, which arranges multiple identical cutouts evenly along a single tube automatically, instead of positioning each one by hand.
The tutorial starts with configuring a single cutout, then shows how the Nesting panel is used to repeat that cutout along the tube, and finishes by loading the completed part into the myCNC machine control interface.
What Happens in This Tutorial
- 1Configure a single cutout’s parameters in the CAD3D Cutout panel — connection angle, diameter, rotation, corner radius, and position on the tube.
- 2Open the saved tube part file, ready for nesting.
- 3Switch to the Nesting panel and set the nesting length, part count, and the distance between each repeated cutout.
- 4Generate the nested layout, which arranges the cutout pattern evenly along the full length of the tube.
- 5Inspect the finished part in the 3D viewer, rotating the tube and reviewing a cross-section of the cutout profile.
- 6Load the completed, nested part into the myCNC machine control interface, ready to run on the CNC machine.
What You’ll Learn
In this tutorial, we demonstrate:
- How to configure an individual cutout’s position and parameters in myPIPE
- How to open and use the Nesting panel
- How to set nesting length, part count, and spacing
- How to generate a nested cutout pattern along a full tube
- How to inspect a nested part in the 3D viewer, including a cross-section view
- How to load a nested part into the myCNC control interface for cutting
Why This Is Useful
When a production run needs several identical cutouts spaced along the same tube, positioning each one manually takes time and creates more opportunities for error.
Part nesting in myPIPE removes that repetitive setup work. Once the nesting length, part count, and spacing are defined, myPIPE lays out the full pattern automatically and keeps every cutout consistent, so the design can be adjusted quickly without repositioning each feature by hand.
Because the completed part loads directly into the myCNC control interface, the same nested layout carries straight through from design to the machine, without re-entering the geometry.
Using This in Real Tube-Cutting Workflows
This workflow is well suited to tube fabrication jobs that call for repeated features along a length of stock — for example, components with a series of mounting holes, slots, or other openings spaced at regular intervals. Defining the pattern once and letting myPIPE nest it along the tube helps keep production runs consistent while cutting down the setup time needed for each part.
