Multiple options should be available (node handles that can be manipulated, a match slope to conduit option in properties, a degree value that can be keyed-in, etc). This should allow for simplified placement of cell nodes that serve as pipe fittings.
@Guest You can rotate a node in plan or type in a rotation using the manipulators, so I think the only thing that's missing is the ability to match the slope to a conduit. Or do you mean the ability to rotate a node in profile?
