I guess the combined projection failed as there was an ovelapping intersection (a line in a view represented as a point in another orthogonal view).
Frankly speaking i tried it myself and could not get the model in less steps than yours.
One other option could be to utilize the bend points co-ordinates for creating the pipe.
We do not do this much, but this is how we used to do it in I-Deas years ago.
We put points at the start and at all of the theoritcal sharp corners.
Then we put a point between these points.
Then we put a coordinate system at each thoeritcal sharp corner. Align the X and Y axis from Orgin point to mid points.
We sketch on each coordinate system draw a line from orgin to mid points.
We add our fillet in these sketches.
This kind of long and drawn out, but this is how we did it years ago.
See Example NX11
I made many tube like this when I worked with companies that made kitchen...
I do as well as in the attached file.
p.s. the value 5x3/2 is the bend radius usually 3/2 of the tube radius.
Many of you may have access to NX Routing Mechanical with your Mach bundles. NX12100, NX13100, and NX13300 include a routing base license that allows you to use basic routing functionality.
While there's several ways to create this using routing, I used a simple way that didn't require me to do any math, just use the dimensions on the pdf directly. (Okay, I did change the default bend radius to 20 by adding half the stock diameter to the inner bend radius. )
I've attached a video.
