I've looked at the Solidworks help, and it plainly says that you can define loads and view stresses relative to a local coordinate system

2016 SOLIDWORKS Help - Coordinate Systems

## Local Coordinate Systems

Local coordinate systems are coordinate systems other than the global coordinate system. You can specify restraints and loads in any desired direction. For example, when defining a force on a cylindrical face, you can apply it in the radial, circumferential, or axial directions. In this case, you need to select an axis as a reference geometry.

Similarly if you choose a spherical face, you can choose the radial, longitude, or latitude directions to apply restraints.

**When viewing results, you can also use reference planes and axes. For example, you can view stresses on a cylindrical face in the radial direction**.

Fair enough. Just how do you do this? I see I can define loads relative to a cylindrical system, if those loads are defined as irregular. I don't see anything regarding stress plots relative to a cylindrical coordinate system, or any way to define a cylindrical coordinate sytem.

Any help?
